Installation and Maintenance Instructions
Model eHorn
Safety Message to Installers
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 servicing this equipment.
• In accordance with FM requirement of 120 dBA maximum
sound level, this product shall be mounted at the minimum
hearing distance from the audible appliance of ten feet.
• For optimum sound distribution do not install this horn where
objects would block any portion of the front of the horn.
• Do not connect this horn to the system when power is on.
• Do not paint the horn. No finish or coating is required. Paint
may obstruct the sound output, reducing the effectiveness of
the horn.
• All effective warning horns produce loud sounds, which
in certain circumstances, may cause permanent hearing
loss. Take appropriate precautions such as wearing hearing
protection. Recommendations in OSHA‑Sound Level
Standard (29 CFR 1910) should not be exceeded.

Mounting the eHorn
The eHorn can be mounted on any relatively at surface with or
without the supplied mounting brackets The mounting surface
must be capable of supporting the weight of the eHorn. Four
installer‑supplied 1/4 in screws are required. Use screws that are
suitable for the mounting surface.

Mounting the eHorn with the Brackets
For dimensions, see Figures 2 and 3 on page 10.
NOTE: For trunnion (U‑bracket) mounting, the Model
EHORN‑TKIT is available as an accessory. Refer to instruction
manual 25500314 for bracket kit details.
To secure the eHorn to the mounting surface:
1. See Figure 1. Attach the mounting brackets to the eHorn
with the six supplied 1/4 in‑20 x 5/8 in screws. Tighten
them to 80 +/‑10 in‑lb.
Figure 1 Brackets attached to eHorn

2. Hold the eHorn against the mounting surface and use the
two mounting holes on the bracket as a template. Scribe
drill‑position marks on the mounting surface.
3. Remove the eHorn and drill a hole at each mark.
4. Secure the eHorn to the mounting surface using installer‑
supplied 1/4 in screws.

Mounting the eHorn without the Brackets
To mount the eHorn directly to the mounting surface:
1. Using the template included with the eHorn (doc. no
25500239), scribe the centers of the six mounting holes on
the mounting surface.
NOTE: For most applications, only four outer mounting
points are necessary.
2. Drill a 9/32 in hole at each of the four scribe marks.
3. Secure the eHorn from behind the surface with the installer‑
supplied 1/4 in x 20 screws. Choose an appropriate length
fastener. Note that the threads in the cover have a depth
of 0.5 in.
Opening and Closing the Housing
Depending upon the model, the factory‑supplied leads are strain‑
relieved to the housing or to the cover.
HOUSING DAMAGE: Use caution and support the housing when loosening
the cover screws. The housing is not supported by any means other than
the cover screws. Once they are loosened, the housing will separate from
the cover.
Opening the Housing
Tools required:
3/8 in socket
6 in extension
See Figure 4 on page 12. Loosen the four cover screws while
supporting the housing so it does not fall. (The cover screws are
retained in the housing.)

Cover Screws (4 Places)
Closing the Housing
1. Verify that the cover gasket is in the groove around the
perimeter of the cover.
2. Align the housing with the cover. Note that the FS logo on
the front of the eHorn needs to be oriented correctly with
the arrow on the inside of the cover or the two parts will
not t together.
3. Tighten the cover screws hand tight, then torque them to
60 in‑lb +/‑ 10 in‑lb.
Wiring the 24 Vdc Model
SHOCK HAZARD: To avoid electrical shock, do not connect wires when the
circuits are energized.
To extend wire for the power connections, use only 12 AWG
to 18 AWG (2.5 mm2to 1.0 mm2) wire. The external leads and
connector must be suitably protected to prevent damage. Use
grommets, bushings, and wires ties to protect them from abrasion.

13
Installation and Maintenance Instructions
Model eHorn
Wiring the eHorn with the Supplied Leads
The power connection is made via the external leads.
To wire the 24 Vdc Model eHorn:
1. Connect the positive (+) lead of the power source to the
red wire.
2. Connect the negative (‑) lead of the power source to the
black wire.
Wiring the eHorn with User-Supplied Leads
If you are not using the external leads supplied with the eHorn,
follow these steps:
1. Strip no more than 0.25 inch (6 mm) of wire insulation
from the ends of the power leads. If you are using stranded
wire, be sure that there are no loose strands outside the
connector plug that could touch the adjacent lead and cause
a short circuit. Torque the terminal screws to 4.4 in‑lb
(0.5 Nm) maximum.
2. Connect the power source positive (+) lead to the (+)
terminal of the connector.
3. Plug and connect the power source negative (‑) lead to the
(‑) terminal of the connector plug as shown in Figure 5 on
page 14.
4. Plug the DC power connector into the power input
connector on the printed circuit board.

SHOCK HAZARD: To avoid electrical shock, do not connect wires when
the circuits are energized.
To extend wire for the power connections, use only 12 AWG
to 18 AWG (2.5 mm2to 1.0 mm2) wire. The external leads and
connector must be suitably protected to prevent damage. Use
grommets, bushings, and wires ties to protect them from abrasion.
To wire the 120 Vac or 240 Vac Model eHorn:
1. Strip no more than 0.25 inch (6 mm) of wire insulation from
the ends of the power leads. If you are using stranded wire, be
sure there are no loose strands outside the connector plug that
could touch the adjacent lead and cause a short circuit. Torque
the terminal screws to 4.4 in‑lb (0.5 Nm) maximum.
2. Connect the power source hot, neutral, and earth ground wires
as shown in Figure 6.

Selecting the Tone
The eHorn is factory‑set to the 55/56 tone. To select the 52 eHorn
tone, move the jumper on the tone generator/amplier board
(Figure 5 on page 14).
Setting the Tone Volume
The volume of the eHorn is adjusted by tap selection on the tone
generator/amplier board.
Activating the Horn
To activate the horn, apply the appropriate line voltage to the horn
power input terminals. The horn remains active as long as line
voltage is present.
