ELECTRONICS EMergency lighting
EMergency lighting EMergency is an electronic system capable of powering LED luminaires also in case of power failure. EMergency guarantees high illuminance levels for long periods of time thanks to a nickel metal hydride (Ni-MH) battery pack and a multi-level charging system. Technology The EMergency system is designed in compliance with the EN 60598-2-22 standard and allows:
• •
To recharge the battery pack in a maximum of 6 hours. To connect a switch for the passage from maintained lighting (emergency lighting on with normal mains voltage) to non-maintained lighting (emergency lighting off with normal
• • •
mains voltage) To supply a maximum power of 6 W during emergency operation. To switch on immediately in case of mains voltage failure To switch to the “Stand-by mode” by means of a N.O. button (which can also be used to switch off and on the LED luminaire during emergency operation; when mains voltage is resumed, the system will get ready for a new emergency event)
Battery The system is fitted with a high-temperature Ni-MH battery pack, compliant with the EN 61951-2 standard, having the following characteristics:
• • •
Over 1-hour duration Environmentally friendly as it does not contain cadmium Constant operation also at high temperature (50 °C) Guaranteed minimum life: 4 years with average use or after approx. 500 charge/discharge cycles
Complete protection The electronic system guarantees the following protections:
• • •
Surge protection Overtemperature protection Protections against overcharge and overdischarge of the battery pack to guarantee the battery life cycle
