Installation and Maintenance Instructions
Model 450E Electronic Horn
Safety Message to Installers and Users
People’s lives depend on your safe installation of our products. 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/or Canadian
Electrical Code and will follow the NEC and/or CEC Guidelines as
well as all local codes. This horn should be considered a part of the
warning system and not the entire warning system.
The selection of the mounting location for this horn, its controls
and the routing of the wiring are 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,
operating, or maintaining 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 horn. You should ensure that the
front of the horn is clear of any obstructions.
• All effective warning horns 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 mounting screws are
tightened.
• Establish a procedure to routinely check the signal system for
proper activation and operation.

Installation and Maintenance Instructions
Model 450E Electronic Horn
• Any maintenance to the unit MUST be performed by a trained
electrician in accordance with NEC Guidelines and local codes.
• Never alter the unit in any manner.
• The nameplate should NOT be obscured, as it contains
cautionary and/or other information of importance to
maintenance personnel.
• Provide a copy of these instructions to the Safety Engineer,
operator(s) and maintenance personnel.
• File these instructions in a safe place and refer to them when
maintaining and/or reinstalling the device.
Failure to follow all safety precautions and instructions may result
in property damage, serious injury, or death.
Unpacking the Horn
After unpacking the horn, examine it for damage that may
have occurred in transit. If the horn 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 discarding
them. Disposal of all shipping materials must be carried out in
accordance with national and local codes and standards. If any
parts are missing, please call Federal Signal Customer Support at
708-534-4756 or 877-289-3246.
An Overview of the Model 450E
SOUND RESTRICTION — Do not paint the horn. No finish or
coating is required. Paint may obstruct the sound output,
reducing the effectiveness of the horn. Failure to heed this
warning may cause serious injury or death.
The Model 450E is a polarized, high-output, continuous duty,
indoor/outdoor-rated, electronic horn suitable for use in re alarm
systems in public mode applications. It is capable of reproducing
coded blasts or sustained tones.

Installation and Maintenance Instructions
Model 450E Electronic Horn
In addition to re alarm system applications, the Federal Signal
450E horn is excellent for general alarm, start and dismissal, coded
paging, and process control signaling in areas of high ambient
noise levels.
The Model 450E can be used indoors or outdoors, depending on
the back box used. When used with the weatherproof Model WB
back box, it meets Type 4X and IP66 requirements.

Wiring the Horn
SHOCK HAZARD — To avoid electrical shock hazards, do not
connect wires when power is applied. Failure to heed this
warning may cause serious injury or death.
WIRING PRECAUTION — An uninsulated section of a single
conductor must NOT be looped around a terminal and used
as two separate connections. NFPA 72 requires that the wire
is severed to provide electrical supervision of the connection
if the wire becomes dislodged from under the terminal.
Failure to sever the wire may render the horn inoperable,
causing serious injury or death.
WIRING PRECAUTION — National Electrical Codes as well
as local codes must be adhered to in the installation of the
Model 450E horn. All electrical wiring must be routed through
approved conduit and fittings as specified. Failure to heed
this warning may cause an electrical shock or render the horn
inoperable, causing serious injury or death.
WIRING PRECAUTION — Refer to NFPA 70 and NFPA 72
(NEC) and CSA C22.1 Canadian Electrical Code, Part 1, Safety
Standard for Electrical Installation, Section 32. Failure to heed
this warning may cause an electrical shock or render the horn
inoperable, causing serious injury or death.
For power connections, use only wire sized 12 AWG to 18 AWG
(2.5 mm2to 1.0 mm2). Strip no more than 0.25"(6 mm) of
insulation from the ends of the power wires. Torque the terminal
screws to 4.5 in-lb (0.51 Nm) maximum.

Installation and Maintenance Instructions
Model 450E Electronic Horn
To wire the horn:
1. Connect the positive (+) lead from the power source to one of
the positive terminals of the connector plug.
2. Connect the negative (-) lead from the power source to one of
the negative terminals of the connector plug.
3. See Figure 3. Connect the remaining positive (+) and negative
(-) terminals on the connector plug to the next horn or an end-
of-line device.
NOTE: This device is polarized by a diode for use in
supervised systems. Refer to local re alarm codes if an
End-of-Line Device is necessary.

Mounting the Horn
SHOCK HAZARD — To avoid electrical shock hazards and
equipment failure, refer to the warning messages to installers
and the installation instructions before installing the horn.
Failure to heed this warning may cause serious injury or death.
There is no specic mounting orientation required for the horn. For
the required spacing between horns, refer to the local re alarm code.

Installation and Maintenance Instructions
Model 450E Electronic Horn
There are three mounting options: Non-weatherproof mounting,
weatherproof mounting, and weatherproof panel mounting.
Non-Weatherproof Mounting
See Figure 4. If weatherproof mounting is not required, mount
the horn on a 4" x 4" outlet box with the two supplied
#8-32 x 1-5/8" screws. Torque the mounting screws to a
maximum of 16 in-lb (1.8 Nm).
Use the two remaining 8-32 screws and Keps nuts to cover the
two unused holes in the horn grille.

Weatherproof Mounting
See Figure 5. For weatherproof mounting, use a Federal Signal
Model WB weatherproof box when a NEMA Type 4X or IEC
IP66 rating is required. The Model WB is gasketed and has
two 3/4"and one 1/2" tapped openings to accommodate 3/4"
and 1/2"conduit. When mounting the horn on the Model WB,
use the provided #8-32 x 1-5/8"screws. Torque the mounting
screws 12 in-lb to 16 in-lb (1.4 Nm to 1.8 Nm).

Weatherproof Panel Mounting
See Figure 6 on page 12. For horn installations that require a
watertight seal when mounted on panel, a at rubber gasket
is supplied.
IMPORTANT: For Type 4X or IEC IP66 applications the surface
must be at and smooth, and all four screws must be used.
To panel-mount the horn:
1. Detach the template (page 4) and place it against the
mounting surface.
2. Mark the locations of the four mounting holes.
3. Remove the template and a drill hole at each mark.
4. Use the dimensions in the template to mark the clearance
hole for the horn, and cut out the hole.
5. Remove burrs and smooth the edges of the holes.
6. Secure the horn and gasket to the panel with the four
supplied #8-32 x 1-5/8"screw and Keps nuts. Torque the
mounting screws 12 in-lb to 16 in-lb (1.4 Nm to 1.8 Nm).
