The surface mounting enclosure houses an ‘intelligent’ DALI/Self-Test LED driver and a Lithium Iron Phosphate (LiFe) battery. A Nichia ‘3Watt’ high power white LED is mounted in the fascia plate in conjunction with a choice of wide angle, narrow angle or ‘corridor’ distribution lens.
The Lithium Iron Phosphate 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 AccessIP unit can be connected to any approved DALI control system. When the mains supply is initially connected, the AccessIP 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 AccessIP 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 a fully interoperative DALI mode.
Incorporating tried and tested emergency driver technology, the AccessIP downlight offers self-contained, non-maintained operation emergency lighting with integral automatic Self-Test or DALI controlled testing from a single product.
The polycarbonate enclosure houses the Lithium Iron Phosphate battery and charger/driver circuit and the appropriate lens is ultrasonically welded into the cover ensuring the IP65 rating (the cover can be rotated through 90° allowing the Corridor lens to be correctly aligned with the escape route). The AccessIP is robust but remains both discreet and attractive.
