Safety Technology International STI 1102 – Frequently Asked Questions

1) What exactly comes in the STI-1102 Stopper II horn kit?
The STI-1102 is a replacement sounder unit for the Stopper II, and the housing shell comes with it. One piece, packed one to a kit, so a single order covers one Stopper II unit. If you have several Stopper II covers on a building and want to swap the sounders across all of them, order one per device.
2) Will the STI-1102 sounder fit any STI stopper cover, or only Stopper II?
Only Stopper II. The 1102 is built as the replacement sounder for the Stopper II line, and the housing shell that ships with it is matched to that unit. If the cover on your door is a different STI model, this horn kit is not the part for it.
3) My Stopper II cover still works but the alarm stopped sounding. Do I replace the whole unit?
No need. The sounder is the serviceable part, and the 1102 kit is the audible alarm module with its housing shell. If the polycarbonate cover itself is intact and the only fault is that the horn went silent on lift or tamper, this kit puts the alarm back in service without pulling the whole assembly off the door.
4) Is the STI-1102 an audible-only alarm, or does it flash as well?
Audible. The 1102 is the sounder portion of the Stopper II, so what you get back after the swap is the horn, not a visual signal. If your facility needs a visual notification on that opening, that is handled by a separate device, not by this kit.
5) Is the STI-1102 replacement horn red, so it matches the Stopper II already on my doors?
Red, same as the standard Stopper II appearance, so a swapped unit on one door won't stand out against the others in the building. That matters on a corridor of exit doors or pull stations where the covers are meant to read consistently.
6) What is the STI-1102 horn kit made of and how heavy is it?
Polycarbonate housing, 0.6 lbs for the kit. Light enough that the existing Stopper II mounting on the door or wall carries it without any change to the fastening, and polycarbonate is the same impact-resistant material used through the Stopper line.
