- Complies with the requirements of GB17945-2010 Fire Emergency Lighting and Evacuation Indication System;
- Modular design with hot-swappable capability to ensure reliable and continuous operation of the system;
- Redundant design for stable performance and high reliability;
- Chinese LCD display showing working status for convenient user maintenance;
- Equipped with reliable protection functions such as output overload protection, short-circuit protection, overheating protection, and battery over-discharge protection;
- Audible and visual fault alarm to indicate fault types, with real-time clock and historical event recording functions;
- Communicates with the system host, uploading its working status to the host to enable centralized monitoring;
- Features fire linkage function, capable of direct linkage with on-site FAS (Fire Alarm System) and BAS (Building Automation System) signals;
- Equipped with mains detection function: when the power in the surrounding fire compartment is cut off, it can automatically switch to emergency working status and upload the information to the host.
Cable Selection and Routing for Centralized Emergency Lighting Power Supply
(1) For output branches of centralized emergency lighting power supplies and control lines of centralized control systems routed in shafts: if there is no fire separation from cables with a combustion performance lower than Class B1 in the shaft, cables with Class A combustion performance shall be selected; if there is fire separation, cables with Class B1 combustion performance may be selected.
(2) For output lines of emergency lighting distribution devices and control lines of centralized control systems: if cables with Class B1 combustion performance are selected, they shall be protected by metal conduits; they may also be routed in cable trays or trunking with the same combustion performance rating; if cables with Class A combustion performance are selected, they may be exposed.
(3) For lighting fixtures installed on the ground or in humid environments, both power supply lines and control lines shall use corrosion-resistant rubber cables, and cable joints shall be treated for corrosion and moisture resistance.
(4) Cables of different voltage levels shall not be routed in the same protective conduit; if they share the same trunking, metal partitions shall be installed in the trunking for separation.
(5) Power distribution branches of the system shall use copper-core conductors, and control lines shall use multi-strand copper-core conductors.

Notes
During power-on, in addition to user-conducted testing according to procedures, random inspections and the following points shall be noted:
- The emergency switching time of the EPS shall be less than 5 seconds.
- When the phase voltage of the main power supply is within the range of 187~242V, the emergency power supply shall not switch to emergency status.
- When the main power supply is under-voltage, the emergency power supply shall automatically switch to emergency output.
- Confirm that the displayed status is consistent with the actual operating status.
- Check the battery pack voltage, main power voltage, output voltage, and their display status when the emergency power supply system is in both main power and emergency working modes.
