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.
