Installation Instructions

1. Turn off AC power.

2. Route AC unswitched circuit of rated voltage into electrical box and
leave 6” of wire length.

3. Remove the exit door by inserting a coin or a screwdriver in a notch at
the top or bottom of the door.
Note: back plate is screwed to the housing.

4. Remove plastic frame with everything attached on the plastic housing.

5. Determine the mounting position (end, wall or ceiling).
Note: canopy is required for end or ceiling mount.

6. Our system can accept input voltages of 120 VAC or 277 VAC.
Therefore, connect the Black (120 VAC) or Orange (277 VAC) and
White (common) leads to the building utility.
Connect the green wire to the ground.
Note: for dual curcuit option, there will be two sets of wires.

Unused primary wire must be insulated to prevent shorting.

b. Remove appropriate hole plugs according to mounting position and

screw canopy on to the frame.

c. Feed AC supply leads through hole and make the proper connection

(See step 5 and Fig.5)

d. Feed the excess wire into the junction box and secure the canopy to

the cross-bar using the canopy housing screws.

7. When required, lift the tip of the diffuser panel (3) to access the chevron
to remove. Support the door around the chevrons with two blocks of
wood. Strike chevron from the inside with a hammer and screwdriver
(See Fig. 4).

8. Connect the battery.

9. Reinstall exit door(s). It is important to direct the green ground wire,
installed in the lower right corner of the unit, before clipping the front
door to the frame.

10. Energize AC. Sign will illuminate.

AC/DC Models

Refer to Fig. 5 for AC & DC wiring.
For DC portion Wire the Red lead (+) to the positive DC input voltage and

the Blue Lead (-) to the negative DC input voltage. Note: DC input voltage
range is 6 volts to 48 volts.

Manual testing

Press test switch. Legend will flicker, but remain lit. On release, external
green LED will illuminate, and automatic charger will restore battery to full
charge. For models equiped with diagnostic function the LED will blink to
indicate an alarm (see table below).

Automatic testing and diagnostic (optional)

The models with the automatic testing and diagnostic option include a
micro-controller which self-tests the unit on a monthly basis and identifies
as well displays failures of the electrical components: battery, battery
charger, lamps, LEDs.

Self-test

The self-test is performed every 30 days for 1 minute, every 6 months
for 30 minutes, and annually for 90 minutes.

Automatic Diagnostic function

The diagnostic function uses an external green LED indicator. The DEL
normally green turn red when an alrm condition is detected; that mean
service is required (See Fig. 6).
