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, the siren housing and into the

siren driver. They will replace 3 of the 4 shorter bolts (“A”) that secure the siren driver to the
speaker housing. Your speaker is shipped with 2 of the shorter bolts installed. A short bolt
must be used in the 2 holes that do not go through the bracket so they 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
