The emergency lighting and evacuation sign system software of the emergency lighting distribution device can be divided into centralized control system and non centralized control. EPS emergency power supply can be completed based on centralized and non centralized power supply.
Advantages of centralized power supply and control system:
1. Complete the transition from nearest evacuation to safe evacuation.
Based on the connection of the fire alarm system, the location information of the fire scene can be quickly and accurately obtained. Electronic computers can automatically generate evacuation plans and operate evacuation routes with excellent emergency lighting markings.
2. Working voltage switch power supply.
The emergency lighting distribution device's emergency lighting is powered by DC24V. The software of the DC24V power supply system is called the dead power system software. Compared to traditional emergency lighting, choose a 220 volt switch power supply. The safety factor has been further improved.
3. Low risk of safety accidents and low maintenance costs.
There is a risk of common faults in the power supply system software of the charging battery terminal equipment of the emergency lighting distribution device; The maintenance and replacement of batteries for emergency lighting lights with backup switch power supply is inconvenient, and the operating cost is relatively high. The competitive advantage of decentralized power supply is significant.
Install emergency sign lighting fixtures for emergency lighting distribution devices.
(1) When installing at the top, do not install at the top. The distance between the lamp top and the ceiling should exceed 200mm; When lifting, metal suspension rods or transmission chains should be used, and the suspension rods or chains should be stable above the engineering building components.
(2) When installed at the bottom in evacuation corridors and corners, it should be installed on a wall 1 meter below the ground level. The surface of the sign should be parallel to the wall, and some raised walls should not have oblique angles or raised fixtures;
(3) When the lighting fixture is installed on the ground, all metal components should be corrosion-resistant or rust proof. The connection of switch power supply and control wire should be sealed with sealant. The surface of the lighting fixture should be parallel to the ground, with a slope not exceeding 3mm and a contact edge not exceeding 1mm with the ground;
(4) During installation, the angle indicated by the arrow symbol or the correct direction for guiding the flow of light should be consistent with the evacuation direction, and should be set on the evacuation routes and critical evacuation safety routes in crowded large and medium-sized rooms.
Installation of fire safety emergency lighting machinery and equipment:
(1) Fire safety emergency lighting fixtures should be uniformly arranged and installed on roofs or side walls at a distance of more than 2 meters from the ground;
(2) When installed on the top of the guide wall, the distance between the bottom and the ground shall not be less than 2 meters. When installing side walls within 1 meter of the ground, embedded parts should be installed. The horizontal distance from the raised wall shall not exceed 20mm. The lighting effect should be below the installation line of the lighting fixtures; Side walls shall not be installed on the ground or between 1-2 meters;
(3) When lifting, metal suspension rods or transmission chains should be used, and the suspension rods or chains should be stable above the engineering building components.
The above are some knowledge points about emergency lighting distribution devices, hoping to be helpful to everyone.
