China Emergency Light Manufacturers – Emergency Lighting System Type Features
China Emergency Light Manufacturers : One way to classify emergency lighting system types is based on how emergency lights are powered. The advantages and disadvantages of the two types of emergency lights will be explained:
The emergency light can contain a power source in the form of a battery, which is called self-contained or single point.
Similarly, power can be supplied from a central battery where the battery is located somewhere within the house and power is supplied to the emergency light through the cable.
Often, the decision to use a central battery or stand-alone system may be cost-determined. If the installation has a long life and low maintenance as a priority, the higher cost of the central battery may be acceptable in very large projects. Often, luminaire costs and installation costs are a major consideration, especially in smaller jobs, and it is this standard that makes stand-alone luminaires the most popular choice.
Self-contained or single point
benefit:
Faster installation and lower cost because no additional power cords need to be run
Standard wiring materials can be used instead of the fire resistant cable required for the central battery source
The power cord cable will automatically meet the lighting requirements of the fixture
Low maintenance costs – regular testing and general cleaning required
Low cost of hardware equipment – no need for extended wiring, extra ventilation, etc.
Higher system integrity because each luminaire is independent of other luminaires
Easily expand your system with additional fixtures
No special subcircuit monitoring required
Disadvantages:
The environmental conditions of the entire system may vary and the battery may be affected by relatively high or low temperatures.
Battery life is limited to 2 to 4 years, depending on the application
Testing requires separate isolation and observation of each fixture
Central battery
benefit:
Maintenance and routing testing is easier, just consider a location
Battery life is between 5 and 25 years, depending on the model
Keep the environment stable in a protected environment. Lamps can operate at relatively high or low temperatures without affecting the battery
Large batteries are cheaper per unit of power and lamps are usually cheaper
Disadvantages:
High capital equipment costs
Installation and wiring are costly because of the need to provide a fire resistant cable such as MICC or Pirelli FP200 for each luminaire
Poor system integrity – any failure of the battery or wiring circuit can cause most of the system’s failure
Requires “battery room” to accommodate battery and charging circuits, as well as potential requirements for ventilation systems
Local power failures in the area of the building may not trigger emergency lighting operations in the area
