INSTALLATION AND SERVICE INSTRUCTIONS

FOR MODEL AV1ST AUDIO VISUAL LIGHTS

SAFETY MESSAGE TO INSTALLERS,

USERS AND MAINTENANCE PERSONNEL

It is important to follow all instructions shipped with this product. This device is to be
installed by a trained electrician who is thoroughly familiar with the National Electric
Code/Canadian Electric Code and will follow the NEC/CEC Guidelines as well as local
codes.

The selection of mounting location for the device, its controls and the routing of the wiring
is to be accomplished under the direction of the facilities engineer and the safety engineer.
In addition, listed below are some other important safety instructions and precautions you
should follow:

• Read and understand all instructions before installing or operating this equipment.

• Disconnect light from the power supply before any installation or maintenance is

performed.

• After installation, test the light system to ensure that it is operating properly.

• After testing is complete, provide a copy of this instruction sheet to all operating

personnel.

• Establish a procedure to routinely check the light installation for integrity and proper
operation.

• The product nameplate, which may contain cautionary or other information of
importance to maintenance personnel, should not be obscured in any way.

Failure to follow all safety precautions and instructions may result in property damage,
serious injury, or death.

I. INSTALLATION

A. Unpacking

After unpacking the light, examine it for damage that may have occurred in transit.
If the equipment 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.

B. Mounting

The Model AV1ST lights are designed for mounting on a flat horizontal surface, a
4” octagonal electrical box, or on a 1/2” NPT pipe. Mounting on a vertical surface
can be accomplished using a separately purchased Model LWMB2 (wall mounting
bracket) or LCMB2 (corner mounting bracket) mounting kit. For weatherproof
installation, lights must be mounted vertically with the lens facing upwards.

1. Pipe Mounting

a. Attach light to pipe by turning clockwise.
b. Refer to section C for information on making electrical connections.

-1-

2. Surface Mounting (See figure 1)
a. Remove the upper housing from the lower housing by removing the three

no. 8 screws.
b. Using the gasket as a template, or the dimensions shown in figure 2, scribe

three drill position marks on the mounting surface. Drill a 3⁄16” (4.8mm)
diameter hole at the two outside drill position marks for mounting. Drill or
punch 3⁄4” (19.1mm) diameter hole at the center drill position mark for wire
entry.

c. Remove the appropriate knockouts in the lower housing using a small punch.
d. Locate rubber gasket on mounting surface and set lower housing on top of

gasket. Secure light to the mounting surface using the provided mounting
hardware.

e. Refer to section C for information on making electrical connections.

C. Electrical Connections

The model AV1ST comes assembled from the factory with two color-coded leads
for wiring to a junction box. If desired, the factory leads can be removed and the
supply connections can be directly made to the terminal block located in the lower
housing as described below.

To avoid electrical shock hazards, do not connect to supply circuit when
power is applied.

If the light has not been disassembled previously for mounting, perform the
following steps:

1. Remove the three no. 8 screws and remove the upper housing.

2. Remove the factory field wiring leads from the terminal block.

3. Route supply wires (12 AWG to 16 AWG) into the housing through the conduit
entry.

4. Strip a maximum of .25” (6.4 mm) of wire insulation from the ends of the
power leads. Connect wires to terminal block by inserting the stripped ends of
the wire into the connector as far as they can travel and tightening the clamping
screw (max. tightening torque = 4.5 in-lb {.5 N-m}).

5. Re-assemble the light and test for proper operation.

II. MAINTENANCE

SAFETY MESSAGE TO MAINTENANCE PERSONNEL

Listed below are some important safety instructions and precautions you should follow:

• Read and understand all instructions before operating this system.

• Any maintenance to the light system must be done with the power turned off.

• Any maintenance to the light system must be performed by a trained electrician in

accordance with NEC/CEC Guidelines and local codes.

• Never alter the unit in any manner. Safety may be endangered if additional openings
or other alterations are made to units.

-2-

• The nameplate, which contains cautionary or other information of importance to
maintenance personnel, should not be obscured.

• After performing any maintenance, test the light system to ensure that it is operating
properly.

A. Lamp Replacement

After extended operation, occasionally check for flash tube degradation. Should
the flash tube misfire, have a noticeable decrease in light output, glow continuously
or darken- replacement is necessary.

High voltages are present inside the light assembly. Wait at least 5 minutes after

shutting off the power before servicing the unit.

1. Remove the lens by loosening the locking screw and turning the lens one­quarter turn counterclockwise.

2. Remove the old lamp by grasping the connector and lifting upwards.

3. Replace lamp with Federal Signal part number K149130A. Install new strobe
tube by fully seating it into the receptacle on the printed circuit board.

4. Attach lens to housing by aligning pins on housing with detents on lens and
turning the lens one-quarter turn clockwise while applying a slight downward
pressure.

5. Tighten locking screw on lens.

6. Test light for proper operation.
