Sign Light Specify Jun 13, 2017

Fire emergency lighting evacuation sign lamp control "Building Design Fire Code", "high-rise civil Building Design fire Code" to the public buildings closed staircase, smoke-proof staircase and its front room, Spectator hall, exhibition hall, multi-function hall, Sign Light restaurant and commercial hall, such as crowded places,Sign Light public buildings in the evacuation corridor, should be set up emergency lighting and evacuation instructions marked light made clear.

For emergency lighting and evacuation lights control requirements, in the "Fire Automatic Alarm system Design Code" 6.3.1.8 states: Fire control room after the confirmation of fire, should be able to cut off the relevant parts of the non-fire power supply, and access to alarm devices and fire emergency lights and evacuation signs.

How to meet the requirements of fire evacuation lighting, Sign Light in high-rise office buildings usually according to fire evacuation needs of public lighting combined with accident lighting, emergency lighting power supply is a dual power supply, and a dual power automatic input device, according to the different load levels of the battery set, Sign Light normal charging standby, the fire mains power supply, emergency battery group power supply, Sign Light and can maintain the power supply 20min above. The fire control center sends out the signal, automatically connects the emergency illumination circuit, guarantees the personnel's safe evacuation.

In the emergency lighting design, the usual use of dual-way power supply, with the local settings with Ni-CD battery lamps, this way there is a two-way power supply, the emergency battery can not be emergency work, Sign Light if the consideration of peacetime control, and to meet the fire in time to connect the accident lighting circuit also need to add a contingency control line, so that the control line is more cumbersome. And scattered, Sign Light a large number of emergency lighting with storage batteries, maintenance workload is larger, especially the replacement cost of battery maintenance is very high. As a result, it is easy to cause the accident lighting with the accumulator is only nominal.

In the design of the improved emergency lighting power supply mode, Sign Light the use of each layer to set up a dual power supply with standby battery distribution box, the distribution box has dual-channel power automatic input and standby battery automatic input function. This circuit can be centralized control open, Sign Light broken, when the fire by the fire control room signal forcibly connected to the emergency lighting and evacuation lighting role.
