Sign Light The Request Jul 07, 2017

How to meet the requirements of fire evacuation lighting, Sign Light in the high-level office space is usually based on the needs of fire evacuation and public lighting combined with accident lighting, emergency lighting power is a dual power supply, Sign Light and a dual power supply automatically into the device, according to the different load levels Equipped with a battery pack, the normal charge standby, the fire when the mains power supply, emergency battery power supply, and can maintain power supply more than 20min. Issued by the fire control center signal, Sign Light automatically connected to the emergency lighting circuit to ensure the safe evacuation of personnel.

In the emergency lighting design, the usual use of dual power supply, with the local set with nickel-cadmium battery lamp program, this way there is a way to double the power supply, emergency battery can not work emergency, if you can consider the usual control, and Meet the fire in time to connect the accident lighting circuit need to add an emergency control line, so that control lines more locks. Sign Light And scattered, the number of more with the battery emergency lighting, maintenance and repair workload is relatively large, especially the battery replacement cost is also high. Therefore, it is easy to cause the accident with the battery accident is just useless.

Design of the improved emergency lighting power supply, Sign Light the use of each set of centralized power supply with a secondary battery distribution box, the distribution box with dual power supply and automatic backup battery automatically put into the function. This circuit can be centralized control on and off, when the fire by the fire control room signal forced connection, Sign Light play the role of emergency lighting and evacuation lighting.

The control requirements of the different circuits drawn from the emergency power distribution boxes are different.

According to the design drawings will be directly from the axis of the bearing structure control axis, will need to be embedded in the metal components or fixed bolt installation dimensions marked clearly, with the civil construction will be embedded iron or bolts installed in concrete, Sign Light can also provide drawings To the civil construction, please civil construction in the construction of iron or bolts buried in concrete, Sign Light because the lampholder should be cast with the roof at the same time.

Lamp mounting plate on the positioning hole, the lamp with bolts plus flat pad and lock washers fixed firmly. Barrier lighting should belong to the primary load, Sign Light should be connected to the emergency power supply circuit. The opening and closing of the lamp should be controlled by an open-air optoelectronic automatic controller, and the outdoor natural environment illumination is used as a parameter to control the conduction of the photovoltaic element to open and close the obstruction lamp. Sign Light Can also be connected to the intelligent building management system, but also the use of time procedures to open and close the barrier lights, in order to have a reliable power supply, Sign Light two power switch should be in the obstruction light control panel.
