Important Notice

Stopper II is intended to be used in areas where the incidence of false fire alarms from manual pull stations is high or has proven to be a serious problem. Any disadvantage of this device is more than balanced when one considers the consequences of false fire alarms, especially if fire service personnel and equipment are responding to a false fire alarm when they are needed for a real fire somewhere else. Add to this the disruption to the facility when false alarms occur. If you have, or may have, a problem with false fire alarms or physical/weather damage to your fire alarm activation devices, the

Stopper II could prove invaluable.

Installation Notes

1. When used outdoors, the manual pull station must also be rated for outdoor use.

2. The relay contacts on Model STI-1100RC, STI-1130RC, STI-1150RC and STI-1155RC, UL

Listing does not permit connection to fire alarm or a life safety function.

3. According to UL Listing, models powered from an external power source cannot be supplied from the fire alarm panel.

4. When properly installed the operation of this cover will not interfere with the function of your life safety system.

5. A backplate and gaskets must be used to achieve NEMA 3R integrity.

6. Horn must be tested annually for proper operation. Battery replacement is recommended annually dependent on use and battery expiration date.

7. If mounting to an uneven surface STI recommends the use of the STI-1280 backplate to ensure proper sealing. If wire access or screw mounting holes are needed, backplate may be drilled as necessary.

Installation Instructions

1. Separate cover and frame leaving cables attached. Slide power switch, on back of horn housing, to “OFF” position (see Fig. 5). Using frame or optional backplate (recommended with all Weather Stopper models) as a template, mark mounting holes on wall taking into consideration

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 9.

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. See Fig. 2.

6. Slide power switch, on back of horn housing, to “ON” position (see Fig. 5).

When power is connected to unit horn should sound.

NOTE: If external power source is used horn will not sound until power is turned on at source.

7. Push switch in to silence horn while tightening switch locking screw (see Fig. 5 for location of screw). This prevents slide switch from being shutoff during unauthorized use.

Gasket Installation

Use of gaskets is necessary to ensure a proper seal in weatherproof applications.

Weather Stopper models ship complete with all necessary gaskets and should be used accordingly. For flush mount weather applications, one STI-3002 must be used between the cover and wall or backplate (see Fig. 3). In surface mount applications, one STI-3002 must be placed between the spacer and wall, while another STI-3002 must be placed between the spacer and cover (see Fig. 4). An STI-3003 or STI-3004 gasket must be used around all entering conduit. For surface mount applications, it is also recommended that the SUB-315 grill be installed in the bottom knockout of the conduit spacer. This helps prevent excessive condensation buildup. STI recommends gasket replacement every five years. (UL requires listing of pull station to be UL Listed for outdoor installations ).

Battery Replacement Instructions

1. Remove the cover from the frame. It is not necessary to remove the cables from the frame.

2. Use a 3/32” allen wrench to loosen the button head screw located next to the switch far enough to slide the switch to the “off” position.

3. Holding the horn housing and cover in one hand, remove the button head screw located on the top of the cover with the same allen wrench.

4. Set the clear cover aside and remove the horn housing cover.

5. Replace the battery with a 9 Volt battery only. Be careful to keep the wires away from the slide switch and the micro-switch.

6. Reassemble the unit making sure that the horn housing fits into the tabs on the horn housing cover; and that this assembly is mounted evenly into the clear cover.

7. Replace the button head screw through the top of the clear cover and into the top of the horn.

8. Slide the switch to the “on” position. The horn should sound.

9. Push the switch in to silence horn while tightening the “on” position locking screw.

10. Replace the cover onto the frame and test by removing the cover from the frame.

The horn should sound when removed and silence when cover is replaced. If unit does not operate correctly, contact Safety Technology International, Inc.
