The THX LED OMEGA provides constant current of 20 - 200 mA to any LED requiring from 10 to 100 V. It uses a 7.2V nickelcadmium battery pack or 7.4V Lithium to provide a minimum of 1 hour emergency lighting duration, depending on the wattage of the lamp. The light output will also vary depending on the wattage of lamps used. The unit complies with SANS-1464-22.

This unit can only be used on LED lamps that have external constant current drivers.

This emergency lighting control unit incorporates a self-testing facility that exercises the batteries and establishes lamp condition on a regular basis. Automatic tests are conducted on monthly basis with full functional tests every 6 months. The monthly tests, of two minutes duration, establish battery and lamp condition whilst the 6 monthly tests last 40 minutes in order to remove battery memory effects. System faults are reported via both audible and visual means.

The self-test feature also removes battery “memory” through regular discharge cycles.

FEATURES:
> Automatic tests reduce maintenance requirements.
> Single unit construction for reduced wiring requirements.
> In a multi lamp fitting only one lamp is affected during tests.
> Satisfies SABS 1464 Part 22.

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 (Luminaires: General requirements and tests) and will satisfy SABS 1464 PART 22 (Safety of luminaires: Luminaires for emergency lighting).
