SELF-TESTING EMERGENCY KIT
The indicating lamp reports the status of the batteries and the lamp by flashing at different intervals. An audible alarm emits a beep every hour of five seconds duration if a system fault is detected. The built in computer establishes whether the lamp is old, the lamp connections are sound, the battery voltage is low (shorted cell), the battery voltage is too high (old batteries) and if the batteries have lost capacity due to ageing.
The user can now be aware of any problems with the emergency lighting system before power failures and not during them. The periodic use of the batteries also prolongs their life. The built in computer also prohibits deep discharging of the batteries. This type of inverter is now becoming mandatory in Europe because users’ needs some guarantee that the emergency lighting is fully functional at all times.
The inverter satisfies the requirements as defined in SABS 598-1 (Luminaries: General requirements and tests) and will satisfy SABS 1464 PART 22 (Safety of luminaires: Luminaires for emergency lighting).
