Alarm Controls SC628 – Frequently Asked Questions

1) What size hole do I need to drill to mount the SC628 buzzer?
A 1-1/8 inch hole. The SC628 Sonalert buzzer is made to mount in a 1-1/8 inch hole on a single gang wall plate, so it drops into a blank stainless plate beside a request-to-exit button or door release station without needing a separate enclosure.
2) How loud is the SC628 buzzer, and is it loud enough for a door prop or forced-door alert?
Sound output is 68 to 80 dB, a medium level with a continuous tone. That carries across a lobby, corridor, or guard desk without being a full alarm horn, which is why it's normally used for door-ajar, request-to-exit acknowledgement, and entry annunciation rather than as a life-safety signal.
3) Does the SC628 come with a wall plate, or do I have to order one separately?
The SC628 is the buzzer element itself, sized for a 1-1/8 inch hole in a single gang plate. Plan on supplying the plate and the single gang box, plus your DC source in the 6 to 28 VDC range and whatever dry contact or relay output will trigger it.
4) Can I combine the SC628 buzzer with a request-to-exit button on the same wall plate?
That's the usual arrangement. Because the buzzer only needs a 1-1/8 inch hole in a single gang plate, it can share a plate with a push button or switch, and both are wired on the same low voltage run since the buzzer draws from the same 6 to 28 VDC band those stations run on.
5) Does the SC628 buzzer have screw terminals or flying leads?
Screw terminals. That means you land your two DC conductors directly on the buzzer with no splicing or crimping inside the gang box, which keeps the install clean when it shares a plate with a push button or key switch.
6) Is the SC628 Sonalert buzzer rated for commercial buildings?
It's a commercial-duty access control accessory. The SC628 is the annunciator Alarm Controls pairs with its door control stations, and it's specified for commercial openings rather than residential use, mounting in a standard single gang plate anywhere you already have a low-voltage box.
