When debugging the automatic fire alarm system, a large number of components are involved, and the response time of each component is a headache for us. The editor will summarize the time involved in this chapter to facilitate everyone to remember. 1.

fire automatic alarm system, a large number of components are involved, and the response time of each component is a headache for us. The editor will summarize the time involved in this chapter to facilitate everyone to remember.

1. Control and display device

4html l15

Device type	Action	Time
Fire alarm controller	Fault alarm	100s
Fire alarm priority/secondary alarm	10s
Area display	Receive and display the alarm signal of the detector	3s
Fire linkage controller	Issuing control signal	3s
Fault Alarm	100s
Graphic Display Device	Receive the signal of the fire alarm controller and fire linkage controller	3s

Gas fire extinguishing controller		Receive and display the feedback signal of the startup device	10s
Fault Alarm	100s
Fireproof Roller Shutter Controller	emits rolling shutter action sound and light alarm	3s

2. Detector

Device type	Action	time
line beam sensing fire detector	0.9dB	does not issue an alarm signal	/
1~10dB	Fire alarm	10s
11.5dB	Fire alarm or fault	100s
Pipeline Sampling style aspiration fire detector	fire alarm confirmation light lit	120s
point flame detector, image fire detector	fire alarm confirmation light lit	30s 3
Combustible gas detection alarm system	Combustible gas detector	Fire alarm confirmation lamp lit	30s
Fault indicator light lit	10 0s
Electric fire monitoring system	Remaining current type electrical fire monitoring detector	Fire alarm confirmation light lit	30s
Temperature measurement type electrical fire monitoring detector	Fire alarm confirmation light lit	40s
Fault arc detector	1s produces 9 and less than half cycle fault arcs	not alarm	/
	1s generates 14 or more half cycle faults Arc	Fire alarm confirmation light lit	30s

3. Fire alarm, fire emergency broadcast

Device type	Continuous working time
Fire sound and light alarm	8s～20s
Fire emergency broadcast	10s～30s

expansion: " Disaster Alarm Controller " fire alarm controller needs to receive two or more fire alarm signals from the same detector (area) to determine that the fire alarm signal is issued, the following requirements should also be met: (1) When the controller receives the first fire alarm signal, it should send out a fire alarm signal or a fault alarm signal and indicate the corresponding part, but it cannot enter the fire alarm state.(2) After receiving the first fire alarm signal, when the controller receives the required subsequent fire alarm signal within 60s, it should emit a fire alarm sound and light signal and enter the fire alarm state. (3) After receiving the first fire alarm signal and the controller still fails to receive the required subsequent fire alarm signal within 30 minutes, the first fire alarm signal should be automatically reset.
