Mounting the electrical box
Figure 1 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 tone
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 4 below.
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.
Tip: Save the jumper by sliding it onto a single pin.

Maintenance
Note: Do not change the factory-applied finishes.
This unit is shipped from the factory as an assembled unit; it
contains no user-serviceable parts and should not be
disassembled.
Perform a visual inspection and an operational test twice a
year or as directed by the local authority having jurisdiction.
