A. Introduction.

Both the AC and the DC Models are installed in identical housings. As a result, all of the installation
instructions in this sheet apply equally to both models.

In all installations, it is recommended that the electrical wiring to the installation site be completed
before the horn is mounted. Installations are subject to local electrical and fire codes.

B. Audibility and Electrical Ratings.

Voltage Current (Amps) Hz dB* dB**
120 0.18/0.22 50/60 100 94

230-240 0.09 50/60 100 94
* Measured on-axis at ten feet/3Meters in an anechoic chamber.
** Underwriters Laboratories ominidirectional sound pressure level rating at ten feet.

C. Basic Installation.

The basic horn installation consists of mounting the horn on an existing 4" x 4" outlet box.

Do not connect wires when power is on.

Connect the horn electrical leads to the power source with user-supplied wire nuts.

To minimize entry of foreign materials and moisture into the housing, ALWAYS install the two

10-32 x 1/2" Phillips head Taptite screws in the holes opposite the mounting screws.

NOTE

The Model 450 contains two red and two black wires. One set of wires (one black and one red) is used for

the incoming power. The other set should be used for the outgoing power. If the outgoing wiring is not

required, the remaining set of wires should be properly terminated. (Diagram A).

Mount the horn on the outlet box using the 8-32 x 1-5/8" screws provided, as indicated in the figure.
(Diagram B).

1. Surface Mounting.

Refer to the introduction, warning message to installers, and basic installation instructions

above before installing horn.

To mount the horn on a wall or other flat vertical surface, mount a Model NB Knockout Box with
four #10 x 1" wood screws (not supplied). Connect the horn’s electrical leads to the power source
with user-supplied wire nuts. Mount the horn on the NB Knockout Box with the two 8-32 x 1-5/8"
screws provided. (Diagram C).

above before installing horn.

A vibratory horn can be semi-flush mounted to a wall with a 4" x 4" electrical junction box when a
Model SF Wall Plate is used. If semi-flush mounting is used, a plaster ring (raised cover) may be
required. A plaster ring is not provided because the depth requirements usually vary from
installation to installation.

Connect the horn’s electrical leads to the power source with user-supplied wire nuts.
Use the four 6-32 x 1/4" slotted head screws to attach the SF Wall Plate to the plaster ring. Use the
8-32 x 1-5/8" screws included with the horn to mount the horn on the plate. (Diagram D).

3. Weatherproof Mounting.

Refer to the introduction, warning message to installers, and basic installation instructions above before

installing horn.

Weatherproof mounting of a vibratory horn requires the use of a Model WB Weatherproof Box,
when a NEMA Type 4X rating is required. The WB is gasketed and has two (2) 3/4" and one (1) 1/
2" tapped openings to accomodate 3/4" and 1/2" conduit. When mounting the horn on the WB, use
the 8-32 x 1-5/8" screws included with the horn. (Diagram E).

4. Flush Mounting.

Refer to the introduction, warning message to installers, and basic installation instructions above before

installing horn.

In order to flush mount the horn, a Model FB Wall Box must be installed in the wall. Use four #10
x 1" screws for mounting the box. Before installing the horn in the box, use the two 10-32 x 1/2"
Phillips head screws to attach the Model FG Grille to the horn. Connect the electrical wiring to the
horn with user-supplied wire nuts and install the horn and grille assembly in the wall box using the
two 8-32 x 2" slotted head screws provided. When installing the horn in the Model FBL Wall Box,
