Emergency or dangerous situations can be avoided by ensuring that the exit lighting system is in proper working condition so as to provide an easy escape route. NHP Electrical Engineering Products has re-designed its emergency lighting test unit in such a way that it is cost-effective, reliable and also meets the standards according to AS/NZS 2293.1 2005 and AS/NZS 2293.2 1995.
Emergency lighting must be inspected and tested regularly to meet the relevant AS 2293 standards. 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.
The two new versions available are:
- ELTS (manual operation via spring return switch)
- ELTK (manual operation via a key operated spring return switch).
When the emergency lighting test switch is in the normal position, lights are connected to the supply, which charges the battery. 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. 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 emergency and exit lights.
