  • What is a fire alarm panel?

    A fire alarm panel is a safety device that commercial buildings typically need to communicate a number of firefighting equipment that can save lives and minimize property damage.

    The purpose of the fire alarm panel is to enable rapid emergency response in the event of a fire so that everyone in the building has the opportunity to evacuate safely. Different fire fighting panels available in the market have different features, so the capabilities of this product can be different. For example, a main fire panel may sound an alarm to alert everyone of danger. Some firefighting panels also communicate with the firefighting center when a fire occurs, and some even activate the building’s sprinkler system to extinguish the fire quickly.

    If you’re not familiar with how a fire alarm panel works, note that when a fire breaks out, the fire alarm panel receives a signal from smoke detectors, a fire sprinkler system, a fire alarm chassis, or a switch in the building. This means that the panel alone cannot detect fire, but it can respond to signals from systems that detect smoke. At that point, the fire panel’s response is activated, which may include making a loud sound and lighting up to warn people of the fire, and then may send a signal to the fire department to send firefighters. Quickly deliver to the place. There are different types of fire alarm panels, the most important and most used of which is the addressable fire alarm panel. This system uses modern technology, as it has a microprocessor that not only sends data from devices in the building to the panel, but also detects changes in electrical currents. Each device in the building’s fire detection system has its own address, so the addressable fire panel can identify which device the signal is coming from. This makes it possible to determine the location of the device that sent the signals to the fire panel.

    Addressable central panel
    What is an addressable fire alarm panel?

    Addressable central panel are fire extinguishing systems that can quickly detect and change the atmosphere and pinpoint the exact location if a problem occurs. These panels are modern systems that operate digitally instead of analog like conventional systems.

    How does the addressable fire alarm panel work?

    The addressable fire alarm panel gets its name from the fact that each signaling device has its own address. An addressable fire alarm system works with a set of networked devices that transmit information directly to a central addressable panel. Basically, a mini computer inside the panel receives these notifications and can identify which signal device the information is coming from. By addressing the active signal device(s), firefighters can quickly identify that a fire is suspected, often before even arriving at the scene. The technology in the addressable fire alarm control panel can automatically notify the emergency services of the fire and its location so that the response can begin immediately.

    These types of central panels are used for fire control in centers with more rooms and spaces than usual. And based on the number of loops, the number of placement of devices in each loop, the length that can be supported in each loop, the ability to detect defects and the technology of code and addressing in detectors and other devices and types of brands are divided and selectable.

    Coded

    Coded panels were the earliest type of central fire alarm control and were developed during the 1800s through the 1970s. An encrypted panel is similar to a regular modern panel in many ways. except that each zone is connected to its own code wheel (ie the alarm in zone 1 sounds the code 1-2-4 [via bells or horns in the building], while zone 2 sounds 1-2- 5), which, depending on how the panel is set, performs sets of four rounds of code until the starting pull station is reset. Large panels can take up an entire wall of a mechanical room with dozens of code wheels. Smaller panels usually only cover one area, so they only have one code. These panels are not common today, but can sometimes be found in older buildings such as university buildings or hospitals.

    Conventional central panel

    Conventional fire control central panels will give you the ability to detect the location of a fire in a zone (one floor) with a reasonable number of spaces (units). In this type of panels, by displaying the zone of the fire, only the area of ​​the fire can be recognized, and the user should be able to find a more accurate location of the fire by being in the desired zone and using the remotes (lights) at the door of each space (unit). Detect fire. Of course, the necessity of the floor zoning guide board next to every conventional central panel is always felt. This type of panel can be selected according to the number of zones, the number of detectors placed in each zone, etc.

    Hamiyar Energy Company, the representative of different brands in this type of panel, will provide you with special services in the field of choosing the best brand with the best price.

    Wireless panel

    Wireless panel

    When we want to install the fire alarm system in a place that is already in use or where there is no built-in wiring, we can use a wireless or wireless fire alarm system. The wireless fire alarm panel has created this capability by communicating with other equipment such as detectors, chassis, sirens, etc. without wires, so that it is possible to use this device when it is not possible to carry out wiring (either built-in or surface-mounted). . Only at the time of buying and installing this device, you should pay attention to the equipment board and the wireless central panel to be in constant communication with each other.

    Fire alarm panel

    Today, the control panel of the fire alarm system is one of the most important components of centers and large projects such as hospitals, medical centers, buildings, factories, hotels, large offices and commercial complexes with multiple units, so that the control panel of a system Fire alarm is one of the integral parts of the mentioned cases. In a control panel, all tasks are performed by microprocessors. Also, the wiring in these systems is in the form of a ring or loop. In this way, the wiring starts from the output terminal of the loop in the control panel and after passing through the equipment, it enters the control panel and the input terminal of the loop again. In the wiring control panel, all the fire alarm items, i.e. detectors, power sources, and sound warning devices are connected to the central part of the control panel.

    These centers are equipped with fault finding circuits, and when a problem occurs, such as one of the batteries being weak, the detector failure, and the fuse burning at some point, it is activated and notified to the control panel center, and the area on fire or malfunction is reported.

    There are different types of control panels, including the following:

    Addressable central panel
    Graphic panel
    Conventional central panel
    Wireless panel

    Below is a description of each of the mentioned items:

     

    Fire alarm panel

    Addressable central panel

    The addressable control panel is an automatic warning system that is created by the combination of open circuit and closed loop system.

    Fire Alarm Panel is the heart of the system where all the devices are serially connected to it. A maximum of 99 to 254 devices can be connected to the control panel in any combination.

    Isolation Module helps to accurately identify the position and location of devices, which is very useful in case of fire.

    The control module controls fire alarm devices such as sounders and hooters.

    In this type of panel, a code has its own identifier, and for that identifier, an address is registered so that its exact location can be registered and reported. If one of the fire detection equipment, for example, a detector, is reported in a fault or error state, detailed information such as the ID, address of the defective part and the type of part can be seen on the addressable control panel screen.

    Identifying the addressable fire alarm equipment, there are two types of hardware and software, which are different in different brands.

    By using the Repeater Panel, the end user can see all the events that happened on the fire control panel, this panel is placed in remote areas or at the entrance of the building to protect the alarm panel from damage.

    The relay module acts like an on and off switch in emergency situations, such as closing the fire door or turning off the air conditioners or turning off other audio systems so that people can hear the alarm.

    The monitor module is usually connected to switches that are the input of alarm devices, while the control module is the output.

    Also, when the MCP glass is manually broken, the hooter or speaker will automatically alarm.

    Using all these parameters, the exact location of the fire can be identified immediately. It protects people by creating alerts. It is applied in all kinds of buildings and places. In fact, in addressable fire control panels, in case of a fire in a part of the building, the exact location is reported so that you can get there as soon as possible and prevent the fire from spreading, and in fact, this is the reason for its name. are “addressable” panels. One of the advantages of an addressable control panel system is that if the loop circuit is accidentally disrupted and as a result cut off, the equipment will not fail and will be fed from the other side of the loop.

    It should be noted that the addressable control panels have a wide range of features and settings, including changing the sound of the siren and changing the sound level, changing the sensitivity of the detectors, creating a night mode and a day mode, categorizing the sirens, etc. as desirable features. have in themselves

    Also, in the addressable control panel, there is no need for a separate route for each of the fire alarm equipment, and all the equipment, including detectors and sirens, can be placed on the loop and next to each other.

    Graphic panel

    In the graphic panel, the status of the parts under control and the report of the occurrence of errors are available. In fact, this panel has made it easier to analyze and connect to other intelligent control systems by displaying graphs of changing status. Most of the graphic panels available in the market are addressable and conventional.

    Conventional central panel

    Conventional fire control central panels will give you the ability to detect the location of a fire in a zone (one floor) with a reasonable number of spaces (units). These panels have been used by many people for many years and still have their fans, despite the small changes in them. These panels include interconnected circuits, all of which are connected to a central panel. Each of these circuits introduces a region or zone. So, in this type of panel, we cannot determine the exact extent of the fire. In fact, in this type of panels, by displaying the zone of the fire, only the area of ​​the fire can be recognized, and the user must be able to find the exact location by being in the desired zone and using the remotes (lights) at the door of each space (unit). To detect the occurrence of fire. Of course, the necessity of the floor zoning guide board next to every conventional central panel is always felt. This type of panel can be selected according to the number of zones, the number of detectors placed in each zone. Because this system does not specify the exact location in a precise display, its price is lower and more affordable, so people still welcome it to some extent and it can be used in small and medium-sized buildings and projects. .

    Wireless panel

    As their name suggests, these panels work without the need for cables and wires, and instead of relying on the power of cables, they use the power of waves. When we want to install the fire alarm system in a place that is already in use or where there is no built-in wiring, we can use a wireless or wireless fire alarm system.

    The wireless fire alarm panel has created this capability by communicating with other equipment such as detectors, chassis, sirens, etc. without wires, so that it is possible to use this device when it is not possible to carry out wiring (either built-in or surface-mounted). Only at the time of buying and installing this device, you should pay attention to the equipment board and the wireless central panel to be in constant communication with each other.Among its advantages:

    being wireless
    Easy installation without wiring
    Keeping the appearance of the building without changing, adjustable
    and high flexibility
    reduction in costs
