Fire alarm system, fire control room, leakage fire alarm system detection

（1） Appearance inspection

1. The category, model, quantity, setting location, installation position, spacing, etc. of fire emergency lighting and evacuation indication signs meet the design requirements. The surface should be free of mechanical damage, and the fastening parts should not be loose. Key points for emergency lighting and evacuation indication signs detection in power inspection. Beijing's designated fire safety inspection enterprise is a designated fire safety inspection institution responsible for electrical inspection in Xicheng District. It can accept fire safety facility inspection and electrical fire prevention inspection for various types of buildings in Xicheng District, as well as fire safety inspection services for various types of large-scale activities and temporary buildings

2. The connection between the lighting fixtures and the power supply line must not be made using plugs, but must be made inside the embedded box or junction box

3. The installation of lighting fixtures should be firm and should not affect the normal passage of personnel. There should be no obstructions or easily confused other sign lights (signs) around, and evacuation indication signs with evacuation direction arrows should be consistent with the actual evacuation direction

4. The status indicator lights for fire emergency lighting and evacuation signs should be normal

Fire emergency lighting and evacuation indicators for built-in power supply and sub bus power supply

The signs should be equipped with main power, charging, and fault status indicator lights, with green for main power status, red for charging status, and yellow for fault status.

Centralized power supply type fire emergency lighting and evacuation indication signs. The emergency power supply should be equipped with main power, charging, fault, and emergency status indicator lights in green, fault status in yellow, and charging and emergency status in red

(2) Basic function inspection

1. Cut off the normal power supply

① Check whether the status and display of the fire emergency lighting and evacuation indication sign system are correct

② Check if there are switches that affect emergency functions

③ Check whether the fire emergency lighting and evacuation indicator signs automatically switch to the lit state within 5 seconds

④ When conditions permit, the duration of the emergency working state can be detected (for emergency lights with batteries, their working time should be ≥ 90 minutes)

2. Check whether the illumination meets the design requirements and relevant national standards

① Use an illuminometer to check the illumination of the ground center between two evacuation lights Whether the illumination of the ground at the center of the passage in front of the light evacuation indicator sign meets the design requirements, and if conditions permit, the illumination when the specified emergency working state duration is reached can be detected.
