C. SIRENS
Models A-120, L-120 and L-240 sirens are intended to be mounted to a rigid surface. Securely
attach siren to the mounting surface by using bolts and washers (user supplied) through the
mounting frame. (After the siren is securely attached to the surface, loosen the hex nuts at the
sides of the siren and adjust the unit to the desired position. Retighten the hex nuts.

SUITABLE ELECTRICAL BOX SUPPLIED BY THE INSTALLER!
The Model A and L sirens are provided with a 1/2-inch threaded conduit opening and 18-inch field
wiring leads. The user supplied electrical box should be mounted as close as possible to the siren
using suitable flexible conduit for connecting them.
