Unpacking the Model AV1-LED
After unpacking the Model AV1-LED, examine it for damage that
may have occurred in transit. If the product has been damaged, do
not attempt to install or operate it. File a claim immediately with the
carrier stating the extent of the damage. Carefully check all envelopes,
shipping labels and tags before removing or destroying them. If any
parts are missing, please call Federal Signal Customer Support at
708-534-4756.
Introduction to the Model AV1-LED
The Model AV1-LED combination audible/visual signal features a
100-percent polycarbonate housing that is rated for Type 3R rain-
tight applications. The Fresnel lens provides superior visibility in all
directions. Available lens colors include amber, blue, clear, green, and
red. Jumper settings enable you to select a fast or slow ash rate and
whether the buzzer and/or LED operate intermittently or continuously.
The AV1-LED design provides three mounting congurations. The
black base will accommodate mounting to a 1/2-inch NPT pipe, a
4-inch octagonal electrical box, or any at surface. The surface-mount
gasket serves as a template for preparing a at surface with appropriate
mounting holes.
All Model AV1-LED units feature a unique twist-and-lock lens to enable
tool-free access to the LED light. The integrated buzzer provides 85 dB
output at 10 ft (95 dB at 1 m). Two voltage variations are available:
24 Vdc and 120 Vac. Each Model AV1-LED is factory-assembled with
two color-coded leads for wiring to a junction box. If necessary, installers
can remove the leads and connect the power supply to the Model AV1-
LED directly to the terminal block located in the base of the unit.
Mounting the Model AV1-LED
This section describes how to pipe-mount and surface-mount the light. To
mount the light on a vertical surface, use a separately purchased Model
LWMB2 (wall mounting bracket) or LCMB2 (corner mounting bracket)
mounting kit (Table 1 on page 18). For weatherproof installation, the
light must be mounted vertically with the lens facing upwards.

Pipe Mounting
To mount the Model AV1-LED on a 1/2-inch NPT pipe:
1. Attach the light to the pipe by turning the light clockwise.
2. To make the electrical connections, refer to “Wiring the Model
AV1-LED” on page 9.
Surface Mounting
To mount the Model AV1-LED on a at mounting surface:
1. Remove and retain the three #8 screws securing the upper
housing to the lower housing. Remove the upper housing.
(Figure 1 on page 8).
2. Using the gasket as a template or the dimensions shown in
Figure 2 on page 9, scribe three drill-position marks on the
mounting surface.
3. Drill a 3⁄16-inch (4.8 mm) diameter hole at the two outside
drill-position marks for mounting.
4. Drill or punch a 3⁄4-inch (19.1 mm) diameter hole at the center
drill-position mark for wire entry.
5. Use a small punch to remove the appropriate knockouts in the
lower housing.
6. Center the mounting holes in the rubber gasket over the
mounting holes in the mounting surface.
7. Center the mounting holes in the lower housing over the
mounting holes in the gasket.
8. Secure the light to the mounting surface using the two mounting
screws.
9. Refer to “Wiring the Model AV1-LED” on page 9 to complete
the installation.

Wiring the Model AV1-LED
The Model AV1-LED comes assembled from the factory with two color-
coded leads for wiring to a junction box. To connect the Model AV1-
LED directly to a power supply, simply remove the factory leads and
make the power connections to the terminal block located in the lower
housing.
SHOCK HAZARD—Do not connect the light to the system while
the power is on. Failure to heed this warning may cause serious
injury or death
Single Power Supply for Light and Sounder
Required for the installation are supply wires of the appropriate size
(12 AWG [3.0 mm2] maximum thickness).
To wire the light to a single power supply for the unit:
1. Turn off power to the system.
2. Remove and retain the three #8 screws securing the upper
housing to the lower housing. Remove the upper housing.
3. Remove the factory eld-wiring leads from the terminal block.
4. Route supply wires of the appropriate gauge into the housing
through the conduit entry.

■ Installation and Maintenance Manual
5. Strip a maximum of 0.25 in (6.4 mm) of wire insulation from
the ends of the power leads.
6. See Figure 3. To connect the wires to the terminal block, insert
the stripped ends of the wires into the connector as far as
they can go, then tighten the clamping screw. The maximum
tightening torque is 4.5 in-lb (0.5 N•m).
7. Reassemble the Model AV1-LED, restore power, and test the
unit for proper operation.

Separate Power Supplies for Light and Sounder
In some applications it may be benecial to control the light
independent of the sounder. If this is the case, separate power
supply wiring for each of the devices can be connected to the
terminal block. Required for the installation are supply wires of
the appropriate size (14 AWG [2.0 mm2] maximum thickness).
SHOCK HAZARD—Do not connect the light to the system
while the power is on. Failure to heed this warning may cause
serious injury or death.
To wire the light and sounder to separate power supplies:
1. Turn off power to the system.
2. Remove and retain the three #8 screws securing the upper
housing to the lower housing. Remove the upper housing.
3. Remove the factory eld-wiring leads from the terminal block.
