Installation Instructions
1. Separate cover and frame leaving
cables attached. Slide power switch,
on back of horn housing, to “OFF”
position (Fig. 5). Using frame or optional
backplate (recommended with all
Weather Stopper models) as a template,
mark mounting holes on wall taking into
consideration placement of pull station
or refer to Fig. 1 for dimensional hole
placement from center of clear opening.
NOTE: Be sure cover will not interfere
with operation of the pull station when
installed.
2. If drilling into masonry or drywall use provided anchors. Drill four 1/4” (6.3mm) holes
approximately 1 1/4” deep. If drilling into wood, drill four 5/32” (3.9mm) holes 1 1/4”
deep. Do not use anchors if drilling into wood.
NOTE: When gaskets are used, install
gasket provided by peeling off backing paper and apply with adhesive facing wall.
Align holes in gasket with holes drilled and stick on mounting surface.
3. If using STI-1280 backplate, refer to Fig. 3 and 4 for install instructions depending
on your application.
NOTE: When drilling hole in backplate NEMA 3R integrity is
compromised.
4. Align frame and put screws through frame holes, into anchors and tighten (if used,
through spacer, gaskets and optional backplate). For STI-1200, continue to Step 8.
NOTE: When using STI-3100 spacer, be sure to install conduit knockout (2 provided),
any additional ventilation (sub-315 grill and sub-316 louver kit), and gaskets before
you tighten to the wall. When using conduit gasket (use STI-3003 with 1/2” conduit
and STI-3100 spacer or use STI-3004 with 3/4” rigid conduit and STI-3104 spacer)
place gasket around conduit in proper location and tighten frame over spacer. For
added protection a bead of silicone may be applied to conduit fitting and between
STI-1280 backplate and wall (Fig. 2). Refer to exploded view of flush and surface
mount installation options Fig. 3 and 4.
