What is an addressable fire alarm center?<\/span><\/em><\/figcaption><\/figure>\nAddressable fire alarm centers are devices that are installed on a signal line with different addresses and on the same signal line, how many devices can be installed, depending on the type of fire alarm cabinet supporting. How many devices can be supported on one signal line?<\/span><\/p>\nThe addressable fire alarm system is more flexible than the conventional fire alarm system, we will know exactly where a fire has occurred because the heat detector smoke detector has a separate address.<\/span><\/p>\n<\/span>Main features of the installation of an addressable fire alarm center<\/span><\/span><\/h2>\n\nThe system determines the point capacity by the number of loops or its signal circuit<\/span><\/li>\nPower and communications will be provided through the loop. At the same time, the loop circuit will monitor all devices connected to it.<\/span><\/li>\nDepending on different manufacturers, the loop circuit can connect over 100 addressable devices. Each loop can contain many different addressable devices. As for the non-addressable devices will be connected to the loop circuit through the address module.<\/span><\/li>\nWhen setting up the address: each address will be connected to a single point on the loop<\/span><\/li>\nThe control cabinet conducts monitoring to all devices in the loop.<\/span><\/li>\nThis system allows people to quickly find the location of a fire. Thanks to the point fire alarm function<\/span><\/li>\nThe system allows multiple systems to support flexible input\/output programming.

Addressable automatic fire alarm system has 3 working states<\/span><\/p>\nWorking principle of automatic addressable fire alarm system<\/span><\/em><\/figcaption><\/figure>\n<\/span>1. Permanent status<\/span><\/span><\/h3>\nIn this state, the system always sends test signals to the base devices. At the same time, attached devices are also programmed to respond to these signals to report working status.<\/span><\/p>\n+ About maintenance and maintenance. In the system will be installed according to a specific period of time to print the operating status of the whole system. Also displays equipment that needs maintenance and replacement.<\/span><\/p>\n<\/span>2. Fire alarm status:<\/span><\/span><\/h3>\n+ When a fire occurs, abnormal factors such as smoke and heat will appear in the environment. When these anomalies reach the set threshold. At this time, the fire detectors will detect and transmit information to the control center cabinet.<\/span><\/p>\n+ At the control center cabinet, the transmitted information will be processed according to the pre-programmed scenario. The cabinet will display the fire alarm signals transmitted at the LCD screen. On the screen will show the full location where the fire is happening. At the same time, the cabinet will transmit signals to peripheral devices so that they can emit warning sounds to humans.<\/span><\/p>\n+ If the fire alarm center is programmed with additional monitoring functions for other devices. In case those devices have problems, the system will notify the supervisor that the device needs to be monitored. This information is displayed on the LCD screen. Once these devices have been monitored and tested, the system will automatically return to its normal state.<\/span><\/p>\n<\/span>3. Malfunction status.<\/span><\/span><\/h3>\nIf in this state, the center receives error signals or does not receive response signals from devices. The system will automatically go into trouble mode. Detailed information about the problem is displayed on the LCD screen. The information will clearly show where the problem occurred. When the problems are fixed, the system will automatically return to the normal working state.<\/span><\/p>\n<\/span>Instructions for installing standard addressable fire alarm centers<\/span><\/span><\/h2>\nNormally, to install an addressable fire alarm system, we follow the following 4 steps. However, during the construction process, depending on the actual situation, the order of steps can be changed.<\/span><\/p>\n<\/span>1. Step 1: Check the drawings, make the construction plan<\/span><\/span><\/h3>\n– Check the investor’s fire alarm requirements and plans<\/span><\/p>\n\u2013 Check the calculation of the overall number of devices on the drawing and the number for each Loop by Loop<\/span><\/p>\n\u2013 Connections, communication with other devices (PA, Elevator, pressure fan \u2026)<\/span><\/p>\n\u2013 Calculate the power used for devices (bells, lights, whistles\u2026) and peripheral devices including control devices, if any, if not enough, an auxiliary power supply must be used for the fire alarm center.<\/span><\/p>\nCheck drawings, make construction plans<\/span><\/em><\/figcaption><\/figure>\n\u2013 Calculation of battery capacity (operating time after power failure \u2013 normally 1 hour normal and 5 minutes fire alarm)<\/span><\/p>\n\u2013 Make the most optimal wiring plan (loop and branch circuits)<\/span><\/p>\n<\/span>2.
