THX_3hrs: three hours emergency duration for switch start ballasts.
THX_1/3hr/E: one/three hour emergency lighting duration for all ballasts
(switch start, electronic control gear and dimming circuits).
THX_1/E HP(40W): for 40W 4 ft fluorescent lamp 50% for 4 ft lamp for electronic control gear
THX_1/E HP(65W): for 65W 5 ft fluorescent lamp 50% for 5ft lamp.
Suitable for switch start and electronic control gear
THX 40/65W 100% E 100% light output for a 4ft or 5ft fluorescent tube, can also give off 50% for a
duration of 2 hours for a 4ft or 5ft fluorescent tube

> 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).

> The unit may be installed without the buzzer connected if necessary.
> Only connect the batteries after a permanent power supply is established i.e., do not switch the unit on and off with the batteries connected during installation as this may cause damage and false error reporting.
> Faults may be cleared by switching off the permanent mains supply and temporarily disconnecting the batteries. This action will reset the internal computer chip.
> After corrective action i.e. replacing faulty lamp or batteries, faults should automatically clear after the next scheduled test.
> Never attempt to replace the lamp during a self test or whilst the unit is in emergency mode. This action may cause damage and false error reporting.
> Whilst the battery is disconnected normal mains function of the emergency lamp is not possible.
