HUBBELL LIGHTING Dual Lite EZ-2 Series Installation, Operation And Service Instructions page 2

General Instructions
This unit is designed for surface mounting on a wall with or without an outlet box. KO's provided for single gang,
4" octagon and 4" square outlet boxes. A breakout on the top of the unit accepts approved surface wiring
equipment or conduit (see Fig. 1). Provide each unit with a single unswitched supply from a 120VAC or 277VAC
branch circuit used for normal lighting in the area to be protected.

Installing The Unit
1. Fasten mounting plate to wall or junction box (Fig. 2).
2. Attach housing to mounting bracket with hinge straps (Fig. 2).
3. Make AC supply connections using approved wire connectors. Select either black lead (for 120VAC) or red
lead (for 277VAC). Cut back and insulate unused lead (Fig. 2).
4. Connect red positive (+) battery lead to positive (+) battery terminal on charger module. See Fig.3 or Fig. 4 on
back cover for terminal location.
5. Swing chassis up and tighten retaining screws (Fig. 1).
6. Energize AC input power.
7. Adjust emergency lamps to desired angle.
Caution: Damage to the battery may occur if the battery is left connected for a long period of time without
AC power.

PLATE
When the AC circuit is initially energized, the status lamp on standard units will typically stay at full brilliance for
several hours before fading to a "dim" state, indicating the battery has charged to its normal float level. On Spec-
tron® equipped models, the green Status LED is iluminated when AC power is present.
NOTE: All models are supplied with an AC Lockout circuit, which prevents the emergency lights from
illuminating when the battery is connected and no AC power is present.
NOTE: All models are supplied with a Low Voltage Disconnect circuit, which prevents damage to the
battery from deep discharge during prolonged emergency operation.
NOTE: Batteries are often shipped in a discharged state – this is normal. The battery will require charging. Allow
several hours of charge before testing the unit.
Models With SPECTRON® Self-Testing/Self-Diagnostic Circuitry
Models equipped with the Spectron self-testing/self-diagnostic electronics system provide:
■ Visual indication of AC power status
—Visual indication of any unit malfunctions including—
■ Battery fault ■ Transfer fault
Spectron equipped units also include:
Brownout protection: unit will automatically transfer to emergency operation upon detection of low AC power
(approximately 80% of nominal line).
Time Delay Retransfer: upon return of normal AC power, unit will remain in the emergency mode for an additional
15 minutes to allow AC power to stabilize.
LED Status Indicators
Two status indicators, one green and one red, are
provided on the control panel of all models equipped
with the Spectron option.
Green Operating Status LED
The green Operating Status LED serves as both an
AC power and a self-test indicator. During normal
operation, the green Operating Status LED will be
illuminated, indicating the presence of AC power. Dur-
ing all automatic or manual self-test cycles, the green
Operating Status LED will blink at a 1 Hz. rate.
Red Service Alert LED
Under normal operating conditions, the red Service
Alert LED indicator will remain "off". In the event the
Spectron controller detects a malfunction, the red
Service Alert LED will blink at a 1 Hz. rate, based on
the following table:
Red Status LED Code Description
One blink ON/pause Battery not connected
Two blinks ON/pause Battery fault
Three blinks ON/pause Charger fault
Four blinks ON/pause Transfer circuit fault
Five blinks ON/pause Emergency Lamp fault
OPERATION
■ Visual indication of self-diagnostic test cycles
■ Charger fault ■ Emergency Lamp fault
Automatic Tests
The unit will automatically initiate a self-test/self-diagnos-
tic cycle based on the following table:
Testing Period Duration of Test
Once a month 1 minute
Once every 6 months 30 minutes
Manual Tests
Using the unit test switch, users can initiate
different duration test cycles based on the
following table:
Initiating Action Test Cycle
Press test switch once 1 minute
Press test switch twice 5 minutes
Press test switch three times 30 minutes
Press test switch four times 60 minutes
Pressing the test switch at any time after a test cycle has
begun cancels the remainder of the test and returns the unit
to normal operation.
