Discuss Emergency lighting question in the UK Electrical Forum area at ElectriciansForums.net
HiUnder loss of power the door should unlock, is this the case? This is a safety feature as if the door remains locked under loss of power people would be unable to escape during an emergency.
HiIf the emergency lights are non maintained (only illuminated under mains failure) they should be powered from the local general lighting circuit. Maintained emergency lights (illuminated at all times) this is not so critical. What was there first the emergency lighting or the door entry systems.
