FunctionalSpecification
Normal(ACmains)operation
LEDs always on at 6W level
Occupancy sensed – LEDs on to Max power with adjustable timeout.
RF system (Microcontroller) broadcasts occupancy sensing to all fixtures on same
channel code – all fixtures respond to all occupancy events.
Battery charging
Microcontroller monitors battery, applies maintenance trickle charge when
fully charged.
Test switch
Momentary switch
Test controlled via Microcontroller
Test lasts at least 30 seconds, but longer if switch is held down longer
Internal relay interrupts DC side of PSU for test
Test LED – bi-color Red/Green
Test LED function RED GREEN
Diagnostic FAILED ON OFF
Diagnostic PASSED OFF ON
Diagnostic in progress Alt-flash Alt-flash
Status LED – bi-color Red/Green
Status LED function RED GREEN
AC Good, battery charged OFF ON
AC Good, battery charging OFF Flash
AC off, on good battery ON OFF
AC off, battery low Flash OFF
Battery FAULT Alt-flash Alt-flash
Battery fault can be:
Battery is failing to charge. Determined by microcontroller that
battery voltage is too low and not increasing at all or fast enough
Battery voltage is too high, indicating an open circuit or bad cell or
disconnected battery pack
Battery Temp too high or too low.
If battery fault continues for more than one minute, it’s assumed
there’s no battery in the fixture (non-backup version) and the Test
light is turned off.
On‐Batteryoperation
LEDs always on at 6W
Occupancy sensed – LEDs on at 50% power level with variable timeout.
