The SA315 Siren Speaker mounting kit comes with 3 long bolts (1/4-20 X 1-1/2” Hex Head SS). The longer bolts are
necessary to go through the mounting bracket, through the siren housing and into the siren driver. They will
replace 3 of the 4 shorter bolts (“A”) that now secure the siren driver to the speaker housing. Your speaker is
shipped with 2 or more of the shorter bolts installed. A short bolt must be used in the hole that does not go
through the bracket so it will properly secure the driver to the housing. If you need to remove all 4 bolts at once be
sure to hold the driver securely in place.
IMPORTANT: For drainage purposes, the speaker must be oriented so that the wire passage hole is in the “6
o’clock” position (closest to the road). This is also the drain hole for the siren. Improper mounting will result in
premature driver failure and void the product warranty.
Mounting Location:
BAIL
BRACKET
The mounting location should be as flat as possible and allow the siren to project its tone
parallel with the road. The rear of the mounting area must be accessible.

2. Position the bail bracket in the exact mounting location and mark off the
