Addressable fire alarm system, installation instructions
Addressable fire alarm system is one of the fire alarm systems that projects need to have. Is the installation complicated? What should I pay attention to when installing? .... The article will explain to you.
Addressable fire alarm system is a modern fire alarm system, essentially a network control system. Installing an addressable fire alarm system is usually not complicated and includes the following 4 basic steps: Addressable fire alarm system
- installation instructionsStep 1: Check the drawing, make a plan to install the system

- Before installing the fire alarm system, it is necessary to check the installation requirements and fire alarm plan of the investor. - Check and recalculate the number of necessary equipment to match the drawings and the number of each Loop.
– Calculate battery capacity (operating time after power outage
– usually 1 normal hour and 5 minutes of fire alarm)
– Calculate the power used for devices (bells, lights, sirens, etc.) and peripheral devices, including control devices, if any. If not enough, use an auxiliary power supply for the fire alarm center.
– Plan the most optimal wiring (loop circuit and branch circuit)

– Pull the wires according to the drawings and proposed plans. In the addressable fire alarm system, there are 2 wires:
+ Signal wire (Signal wire for loop or branch circuit, signal wire from monitoring modules, normal detectors, input of modules)
+ Power cord (Power for the module, power for the bell and light, control power line through the Relay Module)
– Install and arrange equipment according to the determined location plan
– Check the correct installation in the negative (-) positive (+) direction of the signal and source.
– Measure and check continuity, short circuits and other wiring errors.

Step 3: Program the addressable fire alarm system.
– Give fire alarm system cabinet an address or device, receive devices mounted on the loop (this command has different names depending on the type of cabinet)
– If the cabinet has received equipment but is missing the actual equipment, we will handle it as follows:
+ Measure and check the source at the non-receiving device: there are the following two cases A : There is a regular loop source of more than 24 V (check again
– + the cabinet will accept it) B: No Loop source (check the wires may be broken due to wiring errors)
– During the process of the cabinet automatically recognizing the device, if the system reports many unclear errors or hangs, turn off the power to the wire measuring cabinet again.
– There are also some other errors when installing an addressable fire alarm system with the received device:
+ Loss of DC 24V power (recheck the power supply)
+ Open circuit on the input of the monitoring resistors at the Module (Recheck the resistors attached to the module according to requirements)
– Programming controls for other devices as required.
– Program names for commonly placed devices (Location – Floor – Area).
– Connect the program to the addressable fire alarm panel. – Connect the barn door directly on the cabinet or through the bell control module
– Wait for the cabinet to run but check again for errors that arise. Normally, if there is no error, the cabinet will only light up a single power indicator light.
Step 4: Check and accept the addressable fire alarm system.
– Test activation of input devices that affect pre-programmed outputs, check control inputs
– Activate fire alarms in some areas to check the bell signal display name
– Check for errors that may arise on the cabinet
– Handover and Acceptance.
