FAQ OF FIRE ALARM SYSTEM
How can the conventional regional alarm host or combustible gas control sub-system be connected to the centralized control alarm host?
Use centralized control alarm system input module to connect it. It can monitor the fault and alarm information.
Isolation module outgoing line is disconnected and it is still active, how to solve the problem?
Remove and re-wire the input wire. If it is still active, the diode or resistor inside the isolation module has been broken down and the isolation module should be replaced.
How does the gas extinguishing system start the extinguishing agent bottle without the starter bottle?
You can use a solenoid valve to start the extinguishing agent bottle.
Can the smoke exhaust fan be used as an exhaust fan at ordinary times?
Need to use a two-speed fan, high speed exhaust smoke, low speed exhaust air.
Electric fire detector leakage alarm, how to deal with?
Find the leaking cabinet, unplug the device's signal cable, and then re-register the host. Reconnect the wires after repair and re-register it on the host.
The gas fire extinguishing control panel reported the fire, but the centerized fire control unit did not show fire alarm, what is wrong?
1. Please check whether or not the network is ok. 2. If the network is ok, please check the setting of fire and fault etc.
If a fire occurs in the data room, will spraying IG54 or HFM-227E gas damage the running server after the gas extinguishing system is started?
1. IG54 is a gas extracted from the air that does not harm the equipment. 2. HFM-227E gas may pollute the atmosphere, but it does no damage to equipment.
When the fire alarm host is connected at two points, should the exhaust valve be opened and the fan be started at the same time?
The exhaust valve is opened by the two-point linkage of the main panel, and the feedback signal of the exhaust valve is connected to the conventional alarm panel at a single point to start the fan.
