1.Program Overview
Fire emergency lighting and evacuation indicator system of centralized control type is able to test the lamps, circuits and the state of back-up battery of current terminal fire emergency lighting and indicator lamps. When any one of the lamps fails, the control panel should send out a sound-light signal and indicate the fault state.
The system can set the controlling area, evacuation route, evacuation plan, system parameters, working states of lamps (including on/off, timing switch, direction, language, strobe etc.) and other devices flexibly and conveniently according to the changing situation of building’s fire compartment and fire fighting access. When a fire hazard happens, the controlling system will link all the fire emergency lamps to emergency state based on the information passed by fire alarm system and the back-up power will be provided by EPS which is centralized set by system. Evacuation indicator lamps always indicate the nearest safety exit and light on all the fire emergency illumination lamps rapidly in the building to make sure they are visible continuously in the exit passageway. The system can lead people to escape from the smoke and dangerous area quickly and safely.
2.Technology Overview
SANJIANG company intelligent evacuation system adopts centralized control type of centrally supplied evacuation system.
1. System power supply mode
Independent distributive electrical device receives the power supply by EPS, distributive electrical device supplies DC24V to fire emergency lamps without accumulator and the crash time of EPS comply with the requirements in GB17945-2010.
1.System communication mode
By adopting four-wire RS485 signal bus communication, communication bus is non-polarity which can branch out, connect any lamps and achieve the communication function as per request.
2. Lamps control mode
Each fire emergency lamp has its independent addressable code, which can finish the command given by the host and report the information of work status independently. The built-in CPU of lamp can control the lamp for changing direction, strobe and light-off of arrow and it can also monitor work and fault state of the lamp in real time.
3. System load capacity
The system has hierarchical network capability, which can connect 16 control panels at most; each control panel can connect multiple fire emergency powers; each power distributive electrical device can output multiple branch circuits; each branch circuit can connect multiple fire emergency lamps, and the maximum capacity of each control panel can connect 4032 addressable points.
3.Special Solution
Technical advantages of the intelligent evacuation system products of SANJIANG company compared with other products in the market:
1. EPS emergency power is less than 240W and can be put in electrical well separately.
1) zoned applicable
2) layered applicable
2. The system has hierarchical network capability, which can connect 16 control panels at most; each control panel can connect multiple fire emergency powers; each power distributive electrical device can output multiple branch circuits; each branch circuit can connect multiple fire emergency lamps, and the maximum capacity of each control panel can connect 4032 addressable points.
3. By adopting four-wire RS485 signal bus communication, communication bus is non-polarity which can branch out, connect any lamps and achieve the communication function as per request.
