Construction and installation of fire emergency lighting and evacuation indication system

Fire emergency lighting and evacuation indication system is divided into centralized control and non-centralized control according to the control form. The realization of emergency power supply includes centralized power supply and non-centralized power supply. So there are four types of systems: At present, we advocate a fire emergency lighting and evacuation indication system with centralized power supply and centralized control, which has great advantages compared with the other three types.

Realizing the Transition from "Near Evacuation" to "Safe Evacuation"

The fire alarm linkage can quickly and accurately obtain the location information of the fire point. The computer can automatically generate the evacuation plan, control the fire emergency sign lamp, and indicate the evacuation route. Fire emergency lights use DC24V power supply. DC24V power supply system is called "dead system". Compared with the traditional emergency lighting, the lamp uses a 220V power supply. Security is greatly improved. The battery station power supply system has the risk of power failure, the maintenance and replacement of the self-powered fire emergency light battery is inconvenient, and the operating cost is high. The advantages of decentralized centralized power supply are obvious.

Q: How to build a centralized power supply centralized control fire emergency lighting and evacuation indication system?

A: According to the drawing. Necessary technical documents such as system diagram, equipment layout diagram, wiring diagram, installation diagram and fire linkage logic description shall be provided before construction. During the construction process, the construction unit shall make records of construction (including acceptance of concealed works), inspection, debugging and design changes. After the construction process is completed, the construction party shall check the installation quality of the system. After completion, the construction unit shall complete the as-built drawing and as-built report.

The drawing, viewing and statistics of this product system are relatively simple and convenient. Look at the system legend clearly and pay attention to the parameter configuration.

(1) When installing on the top, it is not necessary to install with the ceiling. The distance between the upper edge of the lamp and the ceiling should be greater than 200mm; Metal hanger rod or chain should be used for hoisting, and the upper end of the hanger rod or chain should be fixed on the building structure;

(2) When the low place is installed on the evacuation passage and its corner, it should be installed on the wall 1m below the ground (floor). The sign surface shall be parallel to the wall surface, and the protruding part of the wall surface shall not have sharp corners and protruding fixing parts;

(3) When the lamp is installed on the ground, all metal parts of the lamp should be corrosion resistant or anti-corrosion treatment. The connection between the power supply and the control line shall be sealed with sealant. The surface of the marker lamp shall be parallel to the ground, the height difference between the surface and the ground shall not be greater than 3mm, and the contact edge with the ground shall not be greater than 1mm;

(4) When setting fire emergency sign lights that maintain visual continuity on the evacuation passages and main evacuation routes of densely populated large indoor public places, the direction indicated by the arrow or the flow of light flow should be consistent with the evacuation direction.
