1. The centralized fire alarm controller can directly or indirectly receive other input signals from fire alarms and fault signals, and send out regulatory alarm sound and optical signals that are significantly different from the fire alarm signals. For linkage fire alarm controllers, the signals transmitted by pressure switch , water flow indicator, signal butterfly valve , etc. are sometimes set as regulatory signals.

2. When the centralized fire alarm controller and fire linkage controller receive the fire alarm information, the location information of the fire will be displayed on the screen, the fire alarm indicator light will be turned on, and the fire alarm sound will be emitted, but the sound and light alarm, fire broadcast and the controlled on-site fire equipment will not be activated in a linkage manner.

3. Centralized manual:

(1) display screen status, display "manual";

(2) indicator light status, manual indicator light;

(3) will not start the sound and light alarm in a linkage;

(4) light the fire alarm indicator light.

4. A centralized fire alarm controller (linkage type) can set , multiple html, 2 bus control panels.

5. Fiber Optical temperature sensing:

(1) Petroleum storage tanks except liquefied petroleum gas;

(2) Flammable and explosive places where linear temperature sensing fire detectors are required;

(3) Highway tunnels, railway tunnels and urban tunnels with power cables are laid, etc. (Fiber Optical temperature sensing: liquefied , tunnel )

6, cable temperature sensing:

(1) Cable tunnel, cable shaft, cable mezzanine, cable bridge;

(2) Mixture and stuffy tops of point detectors that are not easy to install;

(3) Various belt conveyor devices;

(4) Other places that are not suitable for point detector installation due to harsh environment.

7. Test the fire alarm and fault alarm functions of linear beam-sensitive fire detector:

(1) Select a filter with a light reduction value of 0.4dB;

(2) Place the filter in the light path of linear beam-sensitive smoke and get as close to the receiver as possible, and use a stopwatch to count;

(3) The fire alarm in 30S should send a fire alarm signal, and the detector alarm confirmation light is lit;

(4) Select a filter with a light reduction value of 11.5dB. (0.4 Fire , 11.5 Fault )

8. The unrecoverable linear temperature sensing fire detector uses the line to simulate .

9. When protecting cables, stacking and other similar protection objects, the linear temperature sensing fire detector should adopt the contact layout. (Stack: Contact)

10. Increase (stable) pressure facilities:

(1) Capsule: Gas and water separation ;

(2) Gas replenishment: Gas and water coexist ;

(3) No negative pressure.

Make a little progress every day, I hope it can help everyone, and I will encourage you!
