SJ-BLJC-Ⅱ1LE3WB2Central controlled fire emergency indicating luminaire powered by centralized battery
Key features
- It can be controlled and powered by two bus with non-polar signal to save installation cost.
- Green LED as light source to lower consumption, longer work life, and easier for replacement.
- Powered by constant current source makes brightness of lights more stable.
- It can be used in most of environments with its resistance of high temperature and corrosion.
1.DC24V safe voltage power supply.
2.Built-in CPU, with independent coding, can correctly report the lamp communication fault, optical circuit fault and running state information.
3.Sampling ultra-bright green LED light source, low power consumption, long life, strong light penetration ability, uniform brightness.
4.Through four bus (RS485 signal bus +DC24V power supply) and the host, the design and construction is simple, convenient, safe and reliable.
5.No battery set, power supply by the system, energy saving, environmental protection, easy maintenance.
6. light source:
6.1Sampling Φ 3 led super bright green, light source models: HH-H52WC-S；
6.2If the fault of the light source is confirmed, remove the LED light source plate and press the new LED light source on it and fix it；
7.daily maintenance:
Every other month, the main power is switched off on the controller, and then the lamp is installed to observe whether the lamp is lit. If it is lit, the lamp is normal. If the light is not on, check whether the connection line is normal. If the connection line is normal, the light source fails and needs to be repaired.
8.Illumination 1.0Lx, suitable for all kinds of places.
