NHP Emergency Lighting Test Unit

Thursday, 18 March, 2010 | Supplied by: NHP Electrical Engineering Products Pty Ltd


The Emergency Lighting Test Unit has been redesigned to make testing emergency and exit lighting more time-efficient. Building codes require that emergency and exit lighting be inspected and tested every six months.

The test unit allows the power to be removed so the emergency lights runs on battery power and can be inspected for operation. It also ensures that charging power is automatically restored after the test.

Two versions are available: the ELTS (manual operation via spring-return switch) and the ELTK (manual operation via a key-operated, spring-return switch).

With the test switch in the normal position, the emergency and exit lights are connected to the supply, which allows their batteries to charge. When the test switch is momentarily switched to the test position, a timer begins to operate and a contactor cuts supply to the emergency and exit lights so that they run on battery power for inspection. The inspection time continues until either the timer times out or the test switch is switched momentarily to the reset position, which will cancel the test and restore supply to the lights.
