Nexus models

Refer to figure 5 for the wiring of Nexus models.
These units can accept an input voltage of 120 or 277 VAC:

120 VAC — Connect the black (120 VAC) lead and white (neutral) lead
to the building utility. Insulate the red wire.

277 VAC — Connect the orange (277 VAC) lead and white (neutral) lead
to the building utility. Insulate the black wire.
Feed excess wire into the junction box.
Leave as much space as possible between the live voltage cabling and
the unsheathed low voltage data cabling.
Run the double insulation of data cables past the line cabling section and
only strip back the last 30mm of the data cable sheathing.

Automatic Diagnostics (Self-Powered Models)

There are three diagnostic indicators: one external and two internal. Unit
must be opened to gain access to internal indicators.
External: General alarm, “Service Required”. The LED will blink if any
alarm condition is detected (see fig. 6).
Internal: Battery Alarm & Charger Alarm. Steady ON if alarm condition
exists (See fig. 7).

Normal operation, No fault — “Service Required” is OFF and one of
the two internal LED blinks, showing that the micro controller is active.

Faulty operation — “Service Required” 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:
