The Main Display interface is the primary user interface in the EST3 Life Safety System. The main display interface focuses on the emergency user by putting information important to the user up front. Hands free, the first highest priority event is shown. The display always gives the last highest priority event. Arriving at the panel and without opening the door the first and last alarm is given. Simple to understand lights and switches help the emergency user execute system commands with confidence.
Ensuring information clarity the 3-LCDXL uses a backlit high contrast super-twist display. 24 lines of 40 characters provide the room needed to convey emergency information in a useful format.
The 3-LCDXL always displays the last highest priority event even when the user is viewing other message queues. Further message flexibility is provided with EST3’s message routing ability. Messages from a node can display at every node on the network or messages can route to specific nodes only. Routing can be initiated at a specific time/shift change. There is no need to have messages display in areas that are not affected by an event.
The EST3 system configures for Local or Proprietary operation in compliance with U.S. or Canadian marketplace requirements. The mode of operation is selected through the System Definition Utility (SDU) which may adjust the following operations slightly to fit the system operation selected.

TFT (Thin Film Transistor) LCD (Liquid Crystal Display) dominates the world flat panel display market now. Thanks for its low cost, sharp colors, acceptable view angles, low power consumption, manufacturing friendly design, slim physical structure etc., it has driven CRT(Cathode-Ray Tube) VFD ( Vacuum Fluorescent Display) out of market, squeezed LED (Light Emitting Diode) displays only to large size display area. TFT LCD displays find wide applications in TV, computer monitors, medical, appliance, automotive, kiosk, POS terminals, low end mobile phones, marine, aerospace, industrial meters, smart homes, handheld devices, video game systems, projectors, consumer electronic products, advertisement etc. For more information about TFT displays, please visit our knowledge base.
There a lot of considerations for how to choose a most suitable TFT LCD display module for your application. Please find the check list below to see if you can find a right fit.
It is the start point for every project. There aretwo dimensions to consider: outside dimension (width, height, thickness) and AA (active area or pixel area). Orient Display’s standard product line ranges from 1.0” to 32”. Our OLED size can go down to 0.66” which fit for wearable devices.
Resolution will decide the clearance. Nobody likes to see a display showing pixel clearly. That is the reason for better resolution, going from QVGA, VGA to HD, FHD, 4K, 8K. But higher resolution means higher cost, power consumption, memory size, data transfer speed etc. Orient Display offers low resolution of 128×128 to HD, FHD, we are working on providing 4K for our customers. For full list of resolution available, please see Introduction: LCD Resolution
Orientation of either landscape or portrait has to be taken into consideration. Beside Aspect Ratio is also very important. You might be satisfied with 4:3 in the past, now, you might be willing to trying wider screen like 16:9 or even 21:9.
TFT screen brightness selection is very important. You don’t want to be frustrated by LCD image washout under bright light or you drain the battery too fast by selecting a super brightness LCD but will be used indoor only. There are general guidance listed in the table below.
Orient Display offers standard brightness, medium brightness , high brightness, and high end sunlight readable IPS TFT LCD display products for our customers to choose from.
If the budget is tight, TN type TFT LCD can be chosen but there is viewing angle selection of either 6 o’clock or 12 o’clock. Gray scale inversion needs to be taken of carefully. If a high-end product is designed, you can pay premium to select IPS TFT LCD which doesn’t have the viewing angle issue.
It is similar to viewing angle selection, TN type TFT LCD has lower contrast but lower cost, while IPS TFT LCD has much high contrast but normally with higher cost. Orient Display provides both selections.
Normal TFT LCD displays provide wide enoughtemperature range for most of the applications. -20 to 70oC. But there are some (always) outdoor applications like -30 to 80oC or even wider, special liquid crystal fluid has to be used. Heater is needed for operating temperature requirement of -40oC. Normally, storage temperature is not an issue, many of Orient Display standard TFT display can handle -40 to 85oC, if you have any questions, feel free to contact our engineers for details.
Power consideration can be critical in some hand-held devices. For a TFT LCD display module, backlight normally consumes more power than other part of the display. Dimming or totally shutdown backlight technology has to be used when not in use. For some extreme power sensitive application, sleep mode or even using memory on controller consideration has to be in design. Feel free to contact our engineers for details.
Genetic Interfaces: Those are the interfaces which display or touch controller manufacturers provide, including parallel, MCU, SPI(,Serial Peripheral Interface), I2C, RGB (Red Green Blue), MIPI (Mobile Industry Processor Interface), LVDS (Low-Voltage Differential Signaling), eDP ( Embedded DisplayPort) etc. Orient Display has technologies to make the above interface exchangeable.
High Level Interfaces: Orient Display has technologies to make more advanced interfaces which are more convenient to non-display engineers, such as RS232, RS485, USB, VGA, HDMI etc. more information can be found in our serious products. TFT modules, Arduino TFT display, Raspberry Pi TFT display, Control Board.
Touch panels have been a much better human machine interface which become widely popular. Orient Display has been investing heavy for capacitive touch screen sensor manufacturing capacity. Now, Orient Display factory is No.1 in the world for automotive capacitive touch screen which took around 18% market share in the world automotive market.
Based on the above three types of touch panel technology, Orient Display can also add different kinds of features like different material glove touch, water environment touch, salt water environment touch, hover touch, 3D (force) touch, haptic touch etc. Orient Display can also provide from very low cost fixed area button touch, single (one) finger touch, double finger (one finger+ one gesture) touch, 5 finger touch, 10 points touch or even 16 points touch
Considering the different shapes of the touch surface requirements, Orient Display can produce different shapes of 2D touch panel (rectangle, round, octagon etc.), or 2.5D touch screen (round edge and flat surface) or 3D (totally curved surface) touch panel.
Considering different strength requirements, Orient Display can provide low cost chemical tampered soda-lime glass, Asahi (AGC) Dragontrail glass and Corning high end Gorilla glass. With different thickness requirement, Orient Display can provide the thinnest 0.5mm OGS touch panel, to thickness more than 10mm tempered glass to prevent vandalizing, or different kinds of plastic touch panel to provide glass piece free (fear) or flexible substrates need.
Of course, Orient Display can also offer traditional RTP (Resistive Touch Panel) of 4-wire, 5-wire, 8-wire through our partners, which Orient Display can do integration to resistive touch screen displays.
If you can’t find a very suitable TFT LCD Display in our product line, don’t be discouraged. The products listed on our website is only small part of standard products. We have thousands of standard products in our database, feel free to contact our engineers for details.
If you like to have a special display, Orient Display is always flexible to do partial custom solution. For example, to modify the FPC to different length or shape, or use as fewer pinouts as possible, or design an ultra-bright LCD display, or a cover lens with your company logo on it, or design an extreme low power or low cost TFT display etc. our engineers will help you to achieve the goals. The NER cost can start from hundreds of dollars to Thousands. In rare case, it can be tens of thousands of dollars.
A fully custom TFT LCD panel can have very high NRE cost. Depending on the size of the display, quantity and which generation production line to be used. The tooling cost can start from $100,000 to over $1M.
As you navigate through the various FAQ pages on our site, you’ll notice that we’ve provided handy pointers that highlight information which might be of special interest in the answers we’ve provided. Look for these symbols in the right hand margin:
Most definitely NOT! Some fire alarm systems employ the ability to remotely download an activity log (to aid in troubleshooting a problem) or make changes (or additions) to the configuration software. In the latter instance, the download must be initiated while a qualified technician is on site (to initiate the communication between the fire alarm panel and the remote site). Once the downloaded changes have been completed, the onsite technician"s responsibilities include resetting the system and ensuring the panel"s operation is properly tested/verified.
Why won"t my addressable fire alarm panel restore properly after the smoke detector has been cleaned? It continues to show that the detector is dirty (or obscured).
You are correct in the way you interpret the rules and regulations. When it comes to fire alarm system service, the BC Safety Authority (as do other provincial regulators) recognizes the difference between "installation" and "repair" (BCSA were, at one point, formulating plans to create a special class of FSR for individuals performing testing and verification of fire alarm systems). When the repair of a fire alarm system comprises a simple "replacement" of a LOW VOLTAGE component, I don"t think there is anyone more qualified than a properly trained fire alarm technician to facilitate the necessary troubleshooting and carry out the needed repair. When that technician also happens to be factory trained, he should be more than qualified to replace actual components in the fire alarm panel over that of someone with an electrical TQ and no formal training on the equipment (or access to the software if additional programming should become necessary as part of the replacement process).
There are many qualified electrical contractors, some of whom work almost exclusively on fire alarm systems. There are also a greater number of contractors who would have difficulty in performing some of the more complex terminations and interconnections required in, say, a Simplex 4100U with full evac (and then only the very foolish would take on the risk of blowing components through an accidental crossed connection). Simplex, Edwards, Notifier, and Mircom all render technical assistance in these endeavours that I don"t believe the Safety Authority would question. Granted, in this last example, such an installation would be completed under the supervision of a licensed electrical trades person (which would also involve an electrical permit). CFAA obtained a ruling in Ontario that I believe should form the basis of nationwide common practice when it comes to actual service on fire alarm equipment. Right or wrong, it"s something that no one here (in BC) has really bothered to challenge.
The Chubb Edwards EST-3 is a fully addressable fire alarm control that employs an LCD display (I think you"ll find this is a common feature of addressable systems). When a "trouble" is indicated, a glance at the main display will more than likely identify the source. If the green "AC" power light is not illuminated, chances are power has been interrupted to the panel. A system "ground fault" will illuminate a dedicated LED on the main display as well as provide an indication on the LCD screen. For other "troubles", use the up and down "scroll" buttons to the right of the display to view individually identified "troubles" on the system. Keep in mind that a "trouble" indication is a very serious condition and that certain key elements of the life safety system could be compromised. Please ensure you notify appropriate service personnel to deal with the situation. You can view a list of common trouble indications HERE!
That depends on what kind of "work" you"re performing. To service, maintain, install, or repair a fire alarm system, you should be qualified if you are a licensed electrical contractor with a valid Provincial TQ. Some jurisdictions will insist that individuals servicing (specifically programming) fire alarm systems be "manufacturer trained" (or employed) to do so (and some require valid CFAA registration). Ontario will allow CFAA Certified Technicians to service and repair fire alarm equipment as long as the work doesn"t involve running new (or replacing) cable and the system they"re working on meets the definition of "low voltage". Alberta is still issuing "P" numbers and many jurisdictions there require a valid "P" ticket, AFSA or CFAA Membership in order to perform service or repair. Most provincial jurisdictions require valid CFAA membership, while many in the Lower Mainland (B. C.) have adopted By-Laws that require only ASTTBC registered technicians, to perform annual testing of fire alarm systems and related life safety equipment.
It goes without saying that you have to be suitably educated with qualified experience to perform service on a fire alarm system. Our best answer? Check with your local AHJ before you commence any "work" on fire alarm or life safety equipment!
You don"t! Unless you"re a trained fire alarm technician capable of performing the required Verification on the affected circuit, you cannot perform service of any kind on a life safety system. While the hookup might appear "easy", it"s best to contact the building"s fire equipment service provider through your property or building manager. If you happen to be the individual that disconnected the speaker in the first place, you could face some very serious repercussions. Tampering with life safety equipment could result in criminal charges or a hefty fine (depending on the mood of the local authority). At the very least, the building"s management could require you to pay the cost of repairing the equipment.
This refers to when the interconnection between the individual fire alarm panels on a networked system is broken (or interrupted) so that the panels are functioning in "stand alone" mode. This is a key test to ensure that the fire alarm panel servicing an area of the building will still perform its programmed functions (sound local signals, home elevators, shut down fans, etc.) should an interruption of the intercommunications loop occur. If a Class "A" circuit is employed this test will ensure that the individual fire alarm panels on the network are still able to communicate with each other on "both sides" of the loop.
I can"t speak to the second question because I don"t represent ULC, but I can speak to the issue of employing parts harvested from a fire alarm panel for use in another (of similar model and manufacture). There are several provisos that we must address in order to properly answer this question. First of all, you must realize that it is illegal for anyone other than manufacturer trained personnel to make board level repairs. In other words you cannot under any circumstances replace soldered components that form (or make up) a common control mother board or any plug-in modules, rail expanders, or chassis. Such repairs can only be conducted at the factory under the strictest supervision and control. There are many instances where fire service providers can successfully harvest plug-in modules and circuit boards from an old system for re-use in another - the most obvious being where a building owner has elected to upgrade to a new system and scrap the existing unit. Many plug in modules may in fact still function adequately and the prudent service provider will stockpile those parts. The difficulty here is that replacing one non-functional part with a previously used FUNCTIONAL module could also entail providing the customer with a warranty on the repair (this is where YOU assume some risk as well). How much of one and what cost to charge is often predicated on what a new (or factory reconditioned) part is worth. You certainly can"t charge the cost of a new part for an old! In some instances, failure of one module on an old system will often be followed by more and at some time the service agency must make a determination as to what"s in the customer"s best interests. Remember also, that replacement of a module (whether it"s old or new) often entails other expenses that might involve additional labour for Verification and related testing.
The debate over smoke detector technologies continues to rage, but in most instances at the time the building is constructed it all comes down to one thing. Ionization detectors are the most prevalent ones you"ll find because, historically, they"ve been the cheaper alternative that meet the requirement of the Building Code for "automatic detection". Are they always the best choice? I don"t believe so, and the evidence that supports this opinion is almost overwhelming.
To provide the "best practice" answer, however, there are several things to consider that will help you to make an informed decision as to which technology to choose. You have to be familiar with the building"s construction. You have to survey the interior fittings and finishing in order to be able to determine what kind of smoke particulate is going to be generated in a potential fire situation. That means you"re going to have to be pretty knowledgeable about the "chemistry" of a fire and how the two detection technologies cope with the vastly different products of combustion.
Now, if, after careful consideration, you"ve determined the best choice is "photo-electric" and the predominant technology in the building is "ionization", the building owner may be looking at expending considerable financial resources for the kind of "upgrade" you"re proposing. Even doing it piecemeal (replacing one or two detectors at a time) may not be an option because you also have to keep in mind that many fire alarm manufacturers specify that you can"t mix technologies on the same conventional input circuit.
In Canada, the suitability of an individual to perform “work” on (or service of) a fire alarm system isn’t as tightly regulated as you might think. If you happen to work for a manufacturer, it’s widely accepted that you have received training sufficient to enable you to identify a defective component and replace it. “Certification” by some jurisdictional authorities may be required as a means to help identify an individual as having met certain educational and experience levels and demonstrate a professional association with an organization that maintains technical oversight over a recognized Standard of Practice. If you can’t demonstrate suitable technical ability, it’s best to check with your local AHJ before commencing any service on a fire alarm system.
In Canada, any fire alarm device connected to a supervised circuit of a Listed fire alarm control must be ULC Listed for the purpose (reference this FAQ for a complete list). Conventional devices that derive power from the control panel in order to function properly (ie. smoke detectors, beam type combination smoke and heat detectors, and flame detectors) must be cross-listed to the specific control panel model as well. On an analogue type system, such as the Chubb-Edwards EST-3 which is the subject of this question, you can interface conventional devices to various initiating modules, but where a conventional smoke detector is involved, it must still meet the cross-listing requirement for the module being used. You cannot, however, use a Notifier analogue module (or active field device) on another manufacturer’s control, even though they may share the same communication protocol as one Surrey based service provider accidentally discovered (and decided to exploit primarily because the Mircom modules were cheaper than those available from the local Notifier rep).
Does current programming certification allow a manufacturer’s technician to program a system that is no longer being produced and which his current training/certification didn"t specifically address? (The real question submitted was: Can a technician with prior experience with Notifier fire alarm systems program an AIM-200?)
Interesting question, and one that came up recently on a job in which an electrical contractor is adding an addressable relay module to an existing (and long obsolete) Notifier 5000 that happens to employ an AIM-200 addressable control module. The good news is that there are a few of us old Dinosaurs still alive and programming (believe it or not). The straight answer is that current manufacturer training does not automatically qualify you to program a panel which you"ve never worked on (let alone seen). Some manufacturers reps will tell you differently, but from my perspective an affirmative answer would then have to work both ways (i.e. if you have training on the older systems you should be able to program the newer ones as well - something I would definitely disagree with). If you’ve never seen an AIM-200 (and never worked on one), you would be in the same category as any other uncertified technician and shouldn’t touch it!
The H355 series heat detectors are designed to operate down to -20 degrees Celsius (according to the specification sheet). The problem is that in areas of high humidity you may wind up with problems due to condensation. My advice would be to first find out how cold “too cold” really is. If it’s below the rated temperature of the detector, then you will have to find another solution to your problem.
There are only two legitimate reasons an installer can block access to the master programming level of ANY system. The first is if the equipment is leased to the end-user (in other words, if the end user didn’t BUY or doesn’t OWN the system). A number or security alarm providers will also restrict access to installer level programming if there is a service agreement in place in order to protect certain programming information that may be proprietary to a central monitoring station or facility.
There are times when a fire alarm system may “latch” into an alarm condition. This is usually caused by an exterior source (such as water ingress into a smoke or heat detector). If you can’t silence the alarm through normal means, it might be helpful to try and identify the source of the alarm and physically disconnect (or remove it) from the system first. If there is no zone indication (the common control may be damaged by water or a power surge), we must first provide some additional words of caution. You may also have a system that incorporates multiple power supplies and sets of batteries. You must be familiar with their location as well as the locations of all of the circuit breakers. This information should be identified on the main fire alarm common control. If it’s not, then please have your service technician do so when he’s next scheduled in to perform service or testing. Have him list the locations of ALL of the panel disconnects.
NOTE: IF THE FIRE ALARM SYSTEM HAS NO AC POWER (the system is running on batteries), and you cannot identify the source of the alarm, it is suggested that you disconnect the notification appliance circuits first (if you cannot silence the system via the normal means). Once the load on the batteries has been reduced, you may be able to reset the system and restore it to a semblance of “normal”. Once the signals are silenced, you’ll have to incorporate a fire watch for your building until such time as the power is restored and you are able to reset the system and reconnect the signalling circuits.
(ANS: “B” is the “correct answer” that was required by the exam from which this question was submitted, as well as this additional commentary in support of the answer).
“This is a class A circuit in fire alarm which means the end of line (EOL) resistor is in the fire alarm panel. The question indicates that the EOL developed a short circuit which means that it short circuited the fire alarm panel. The circuit over-current device will operate which means the circuit breaker protecting the panel will trip.”
“ANS: B” is actually only partially correct. The question actually features two correct answers (either “A” or “C”) and could use some editing to further clarify the the examiner’s intent. ULC tests fire alarm panels to a Standard called the “Standard for Control Units for Fire Alarm Systems” (CAN/ULC-S527). A SHORT on a conventional input or output circuit CAN NOT affect the normal operation of another input or output circuit regardless of whether it’s wired in a Class “A” or a Class “B” configuration. This operational requirement is articulated in CAN/ULC-S527-11 (Amendment 1) Section 4.6 “Input Circuit Operation” and Section 4.8 “Output Circuit Operation”. A SHORT across a conventional input circuit will result in an ALARM (or a latching SUPERVISORY event if the circuit is monitoring a sprinkler valve) on the system. A SHORT on a conventional signalling (output) circuit will result in a TROUBLE condition on the system. Fire alarm panels are designed to ensure that a shorted output circuit will NOT switch from the supervisory condition, but if it’s been programmed to power signals in suites protected by signalling isolators (or the SHORT occurred on the panel while it was sounding an ALARM), the circuit is protected by an self-restoring MOV (which would also only trigger if the short was imposed ahead of the suite sounder isolator). This is where “ANS: B” is only partially correct. Once the SHORT is removed, the circuit will return to normal operation (if it’s an output circuit or Data Communication Link circuit). A SHORT on a conventional input circuit would require a system-wide RESET once the circuit was returned to normal operation.
Note: Initiating a short condition on conventional and addressable input/output circuits of a fire alarm control panel is one of the required tests performed ANNUALLY on fire alarm systems in Canada (as part of our testing Standard, CAN/ULC-S536). It is important to note that a short condition on any alarm input or output circuit will NOT result in the circuit breaker (circuit disconnecting means) protecting the fire alarm control to trip.
SEOUL (Reuters) - Samsung Display plans to spend 13 trillion won ($11 billion) to upgrade a South Korean liquid crystal display (LCD) plant so it can manufacture more advanced screens, Yonhap news agency reported on Tuesday.
Samsung Display, a unit of Samsung Electronics Co Ltd and an Apple Inc supplier, will announce the investment next month, Yonhap said, citing unidentified industry sources. It did not mention a timeframe for the investment.
A spokeswoman for Samsung Display, which operates two LCD production sites in South Korea and one in China, said nothing had been decided on its future investment plans.
South Korea’s panel makers have been struggling to cope amid slower LCD demand for TV and smartphones as well as rising competition from Chinese rivals and a shift by major clients to organic light emitting diode (OLED) panels.
