Emergency Lighting Automatic Test Timer

Time ranges between 10 min, 30 min, 60 min, 90min, 2 hours & 3 hours
Bright green colour makes it easily distinguishable from other components on the Electrical switch board
Pressing the integrated test key forces the output relay to switch into on-position, so the emergency lights are disconnected from the mains and the set interval begins. After the interval has expired the output relay switches into off position and the emergency lights are reconnected to the mains.
