Installation
WARNING: Electrocution hazard. To avoid personal injury or
death from electrocution, remove all sources of power and
allow stored energy to discharge before installing or removing
equipment.
To install the temporal horn:
1. Select and install a suitable electrical box. See “Mounting
the electrical box” on page 2 for details.
Note: Outdoor installations require a weatherproof
backbox.
2. Set the tone and pattern. See “Selecting the volume and
pattern” on page 2 for details.
3. Bring the signal circuit field wiring into the electrical box.
4. Position the mounting plate on the electrical box with the
hook flange up and facing outward as shown in Figure 2.
Fasten the plate using the screws provided.
5. Connect the signal circuit field wiring. For the unit to
function properly, observe polarity. See Figure 1.
For additional wiring details, see the installation
instructions for the signaling modules or circuits used in
the fire alarm control panel.
6. After completing the connections, attach the unit to the
mounting plate, as noted below.
a. The grille has tabs (at the top of the inner face) that
engage with the hook flange on the mounting plate.
Angle the bottom of the grille out slightly, and then
slide the unit into place so that the tabs engage the
flange.
b. Seat the grille by pressing the bottom in.
c. Fasten the bottom of the grille to the mounting plate
by tightening the captive locking screw.
7. Apply power and activate the unit to verify that it is
operating properly.
Figure 1: Typical wiring diagram
Note: Electrical supervision requires the wire run to be broken
at each terminal. Do not loop the signaling circuit field wires
around the terminals.
Install this product in accordance with applicable requirements
in the latest editions of NFPA 72 National Fire Alarm and
Signaling Code, CSA C22.1 the Canadian Electrical Code, Part
1, Section 32, CAN/ULC-S524 Installation of Fire Alarm
Systems, and in accordance with the local authority having
jurisdiction.

Mounting the electrical box
Figure 2 shows mounting details for:
• Standard box. When using a 4 in. square box, use an
extension ring for additional wiring space, if needed. If
using a double-gang electrical box that is 2-1/2 in.
(64 mm) deep, locate the conduit only at the rear of the
box.
• Weatherproof box. Peel off the adhesive backing from the
gasket and adhere to the box.
• Surface mount box.
Selecting the volume and pattern
The horn has a jumper for selecting a high or low volume
output level. The default is high volume. To set the output to
low volume, remove the output jumper from the circuit board
on the rear of the unit. See Figure 3.
The horn has a jumper for selecting either a temporal or steady
tone. The default is temporal tone. To set the output to steady
tone, remove the tone jumper from the circuit board on the rear
of the unit. See Figure 3.
Tip: Save the jumper by sliding it onto a single pin.
