Self-Powered Models
Manual testing
Press test switch. Legend will flicker, but remain lit, AC pilot lamp will
extinguish. On release, pilot lamp will illuminate, and automatic charger
will restore battery to full charge.
Automatic testing and diagnostic
All models have automatic testing and diagnostics which includes a
micro-controller that exercises, self-tests, the unit on a monthly basis and
identifies and displays failures of the electrical components: battery, bat-
tery charger, lamps, LEDs.
Self-test
The self-test is performed every 30 days for 30 seconds, every 60 days
for 30 minutes, and annually for 90 minutes.
Diagnostic function
The diagnostic function uses three red LED indicators: one external,
near AC pilot lamp, and two internal, inside the unit. The unit has to be
opened to read the status of the internal indicators.
External: Service Required. Blinks if any alarm condition is detected
(See fig. 8).
Internal: Battery Alarm, Charger Alarm. Steady ON if alarm condition
exists (See fig. 9).
Normal operation, No fault — Service Alarm is OFF and one of the two
internal LED blinks, showing that the micro controller is active.
Faulty operation — Service Alarm blinks.
Battery Alarm ON, Charger Alarm OFF: Check battery or replace battery.
Battery Alarm ON, Charger Alarm ON: Check LED strip.
Battery Alarm OFF, Charger Alarm ON: Check charger circuit.
Nexus models
Nexus models use two local indicators. One is a green LED for AC pilot
lamp. The other is a tricolor LED (Service) which identifies and displays
the Nexus status. The table below describes each status:
