SAFETY NOTICES
WARNING
Failure to follow all safety precautions and instructions may result in property damage,
serious injury, or death to you or others.
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 Electrical Code and will follow
the NEC Guidelines as well as local codes.
This device may be considered a part of the signalling system and not the entire signalling system.
The selection of the mounting location for the device, its controls and the routing of the wiring is to
be accomplished under the direction of the facilities 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.
• Do not connect this unit to the system when power is on.
• Optimum sound distribution will be severely reduced if any objects are in front of the speaker.
You should ensure that the front of the speaker is clear of any obstructions.
• All effective warning speakers produce loud sounds which may cause, in certain situations,
permanent hearing loss. You should take appropriate precautions such as wearing hearing protection.
• All effective warning speakers produce loud sounds, which may cause, in certain situations,
permanent hearing loss. The device should be installed far enough away from potential listeners
to limit their exposure while still maintaining its effectiveness. The OSHA Code of Federal
Regulations 1910.95 Noise Standard provides guidelines which may be used regarding
permissible noise exposure levels.
• After installation, ensure that all screws and threaded joints are properly tightened.
• After installation, test the unit 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 unit installation for integrity and proper operation.
A. General.
The Federal LSH Sound Module is an audible signalling device, designed for use as the top
module on the LiteStak. It contains a volume controllable piezo alarm. The desired sound
level can be set by adjusting the piezo's built-in shutter-type volume control. The solid state
piezoelectric design offers low power consumption, no R.F. interference, no moving parts for
high reliability and long life. The Federal Sound Module is available in 24VDC, 120VAC,
and 240VAC Models LSH-024, LSH-120, and LSH-240 respectively. This device is UL
(Underwriters Laboratories) Listed for indoor use.
B. Unpacking.
After unpacking the Sound Module, examine it carefully for possible damage that may have
occurred in transit. If the equipment has been damaged, immediately file a claim with the
carrier stating the extent of damage. Carefully check all shipping labels and tags for special
instructions before removing or destroying them.

C. Power Requirements.
Load consisting of 1 Sound Module: 0.07A, 24VDC
0.04A, 120VAC
0.04A, 240VAC
Load consisting of 4 Light Modules and 1 Sound Module: 2.07A, 24VDC
0.84A, 120VAC
0.44A, 240VAC
D. Electrical Connections.
WARNING
To avoid electrical shock hazards, do not connect wires when power is applied.
The Sound Module is a plug-in unit completely wired at the factory and does not require
any additional wiring. The Sound Module is controlled by the white/black wire in the Base
(Model LSB). See Table 1. Since the white/black wire also provides control to the Clear Light
Module, a Clear Light Module cannot be installed in a LiteStak which contains a Sound
Module. The control wire for the Sound Module and each Light Module in the LiteStak must
be connected to a control device. See figures 1 through 3 for examples of wiring the modules
to a control device. Control device rating must be capable of handling the power requirements
shown in paragraph C. above. For additional information on Base and Light Module installation
and electrical connections, refer to the appropriate instruction sheets.
E. Sound Module Installation.
CAUTION
Do not install the Sound Module, or any of the Light Modules, when power is on.
NOTE
The Sound Module must be the top module on the LiteStak.
After wiring of the base is complete, any Light Modules to be installed are assembled to the
Base in the color sequence determined by the user. To install the Light Modules, refer to the
appropriate instruction sheet. The Sound Module is designed to be plugged-in as the top
module on the LiteStak. Up to four Light Modules (LSL’s) may be assembled on the Base
with the Sound Module (LSH) installed on top of the uppermost Light Module. The Sound
Module can be assembled directly on the Base provided it is the only module installed.
See figures 1 through 3 for examples of mounting the Sound Module. To install the Sound
Module, proceed as follows:
1. Observe the orientation of the two 3-pin connectors. Position the Sound Module on top
of the Base if it will be the only module, or on top of the uppermost Light Module.
Make sure that the male and female connectors are properly oriented. Align the connectors,
and press the Sound Module until it snaps into place.
2. See figure 4. There are four holes located near the edges of the Sound Module’s clear
bottom plate which align with the holes in the Base or Light Module beneath it. To secure
the units together, fully install one snap rivet (supplied with grille kit) in each of the 4
holes. Press the head of each rivet until it snaps in place.
CAUTION
Damage to the LiteStak can occur if the modules are improperly secured. Check that all four
snap rivets are completely installed in the Sound Module and in each of the
Light Modules on the LiteStak.
NOTE
The snap rivets may be pried out with a flat blade screwdriver.

3. Retain the four plastic pins that come with the cap (supplied with the Base unit). Install the
cap on top of the Sound Module by aligning the two split pins on the cap with the snap
rivet holes in the Sound Module’s top plate. Press down on the cap until it snaps in place.
See figure 4. Secure the cap in place by fully inserting one plastic pin in the center of each
of the cap’s split pins through the hole in the circuit board.
NOTE
Two (2) of the four (4) plastic pins provided with the cap are spares.
4. Included with the Sound Module is a grille kit. Position a grille on the widely spaced pins
with the slots on the grille facing downward. Push the grille over the slanted pins until the
grille snaps in place. Repeat with the other grille.
NOTE
For proper sound output, ensure that the grille is installed correctly.
5. Test the LiteStak to ensure that it operates as intended.
F. Service.
The Sound Module contains no user serviceable parts inside.
Federal Signal will service your equipment or provide technical assistance with any problems
that cannot be handled locally.
Any units returned to Federal Signal for service, inspection, or repair must be accompanied
by a Return Material Authorization. This R.M.A. can be obtained from the local distributor
or manufacturer’s representative.
At this time a brief explanation of the service requested, or the nature of the malfunction,
should be provided.
