3、 Automatic fire alarm system

Leakage area of fire alarm system

1. The indoor residents of super high-rise buildings are not equipped with detectors.

2. Install detectors in strong and weak electric wells.

3. Detectors are installed in the water pump room, fire control center, and various equipment rooms.

4. Floor displays are not installed in public areas.

5. There is no combustible gas detector installed in the kitchen.

fire line

1. All exposed steel pipes related to fire protection have not been coated with fireproof coating or the fireproof coating is unevenly applied.

2. The metal hose connected to the device is not in place.

3. The wiring boxes in the exposed and suspended ceilings are not covered with cover plates.

4. The internal distribution wires of the suspended ceiling are not threaded through pipes.

The linkage control and related functions are incomplete

1. The access control system has not implemented power-off control.

2. The normally open electric fire door is not linked and controlled.

3. The one-way escape lock is not linked and controlled.

The logical relationship of the fire linkage control system is chaotic

1. The detector in the corresponding area has triggered an alarm, and the positive pressure air supply fan in the corresponding area has not started.

2. When a wind turbine is responsible for multiple smoke prevention zones, the detectors in the smoke prevention zones will sound an alarm and all air vents will be opened.

3. Manually open the smoke exhaust outlet and positive pressure air supply outlet, but the corresponding fan has not started.

4. Non fire power outages and emergency lighting forced switching are not included in the linkage relationship.

5. When the alarm was triggered in the atrium area, the rolling shutter doors on each floor did not activate.

6. When large space detection devices such as dual band, cross section, and linear detectors alarm, they are not linked to the relevant conventional fire alarm system.

7. The fire-fighting air supply fan is not included in the linkage relationship for starting in case of fire.

8. The smoke exhaust valve at the entrance of the smoke exhaust fan is not interlocked with the smoke exhaust fan.

control center

1. The wires introducing the fire alarm controller are not tied into bundles and are not labeled with numbers.

2. The grounding branch of the control equipment is less than 4mm ²;.

3. The distance from the back of the control device to the wall operation is less than 1 meter.

4. The CRT is not yet complete, and there is no response on the CRT interface after an external device alarm.

5. The fire control host has shielding and fault points.

Fire telephone system

1. The host cannot make extension calls.

2. The fire outside telephone is not set up.

3. The elevator machine room and important non equipment rooms related to fire protection are not equipped with telephone extensions.

4. The installation of the fire telephone extension is not secure, and the installation position of the telephone extension is unreasonable.

4、 Other possible reasons

1. The civil engineering and decoration work within the scope of acceptance is not yet completed.

2. The mechanical and electrical installation related work within the acceptance scope is not yet completed.

3. Municipal power supply and water supply are not in place.

4. The diesel generator cannot start or its automatic switching function has not been achieved.

5. The fire elevator button and three-way communication have not been completed.

6. Failure to produce signage in accordance with the relevant requirements for fire safety identification.

7. The PVC pipe passing through the floor is not equipped with a fire-resistant ring.

8. The building fire extinguishers, fire hoses, water guns, etc. are not properly arranged.

9. Failure to install escape door locks in accordance with relevant requirements.

10. Some equipment rooms and elevator machine rooms are not equipped with emergency lighting, and the emergency lighting illumination in the fire control room and important equipment rooms is insufficient.
