Enclosure Installation (optional)
2.3.1 Installing the Detector on the Swivel Mount (SM2) or SS Extra Duty (SM4) Swivel Mount
a. Select fasteners for the swivel mounting such that they will secure it to the type of material at the
enclosure location.
b. Mount the swivel-mount to the wall assuring correct orientation.
c. Install the mounting bracket onto the Model SS4-A/-A2 Detector enclosure using the #¼-20 or #6
mm screws and nuts provided. If oriented correctly, the outside contours of the mounting ears on
the Detector enclosure and the ends of the bracket will match. The large diameter of the threaded
insert should face the enclosure.
d. Screw the enclosure/bracket assembly onto the ball or swivel stud. Turn the Detector until the stud
bottoms against the enclosure. Do not tighten. While holding the enclosure, tighten the jam nut
against the bracket.
e. While holding the enclosure, loosen the socket head screw on the SM2 swivel-mount or swivel
release bolt on the SM4. Position the enclosure in such a way that the conduit openings are located
horizontally at the bottom. Point the enclosure in the desired direction and tighten the appropriate
hardware.
