The surface or recessed mounting enclosure houses an ‘intelligent’ proSeries DALI/Self-Test LED driver and a Lithium Iron Phosphate (LiFe) battery. A Nichia ‘3 watt’ high power white LED is mounted in the fascia plate in conjunction with a choice of wide angle or ‘corridor’ distribution lens.
The Lithium Iron battery technology ensures long life without the thermal concerns associated with the more common Nickel Metal Hydride battery technology.
Fully integrated components and the latest software ensure that the Access luminaire can be connected to any approved DALI control system. When the mains supply is initially connected, the Access circuit initiates the Self-Test commissioning mode and then activates the weekly and annual test routine starting at random times to ensure tests do not get carried out simultaneously in the same areas. Faults such as charge failure, battery failure, etc. will be indicated locally by a bi-colour LED. The Access luminaire will continually be prepared for a DALI signal even when operating in Self-Test mode. If a DALI signal is received the Self-Test mode will be disabled and the circuit will adopt full DALI mode.
