wire with neutral; black (120Vac) or orange (277Vac) to line voltage. Unused primary wire must be insulated to prevent shorting. Con nect

green wire to the ground. b. Reconnect the lamps on terminal blocks (L1+/L1-). c. For units with remote capacit y , connect the remote head s DC+ to L1+

and DC- to L1-. d. Connect the battery to the charger board.

Manual Testing

Operate the magnetic “test switch” by holding the provided magnet where indicated near the LED display (see figure 5). This will initiate a one minute test. The DC lamps will illuminate for approximately one minute, then the unit will automatically return to stand by mode. Test can be cancelled by holding the magnet near the test switch again.

Automatic Testing

The unit will perform an automatic self-test of 1 minute every month, 10 minutes every 6 month and a 30 minutes self-test once a year.

Automatic Diagnostics

There are five diagnostic indicators: one externa l and four i nternal. Unit must be opened to gain access to internal indicators. External: Servicel alarm, “Service Required”. The LED will turn-on if any alarm condition is detected (see fig. 5). Internal: Battery Failure, Battery Disconnect, Charger Failure & Lamp Failure. Steady ON if alarm condition ex ists.

Normal operation, No fault — “Service Required” is OFF. Faulty operation — “Service Required” is ON.

(see AD charger owner manual for more details)

Nexus models

Nexus models use two local indicators. One is a green LED for AC pilot lamp. The other is a bicolor LED (Service) which identifies and displays the Nexus status. See Nexus addendum for details.
