Alarm Controls AI-624 – Frequently Asked Questions
1) What size hole does the Alarm Controls AI-624 audio alert indicator need in the wall plate?
The AI-624 buzzer drops into a 1-1/4 inch hole on a single gang wall plate. If you would rather not cut a plate, it can also be flange mounted to a flat surface. Plan the 1-1/4 inch opening before you commit to a plate.
2) How loud is the Alarm Controls AI-624 and is it enough for a lobby or corridor?
Rated at 92 dB with a continuous tone. That is loud enough to be heard across a lobby, a corridor, or a guard station, but there is no pulsing or warble option, so if you need a distinguishable pattern for different alarm conditions, use separate devices rather than relying on tone changes.
3) Does the AI-624 come with wiring, or do I need to supply terminals?
The buzzer ships with wire leads already attached, so you splice it into your circuit rather than landing wires on screw terminals. Budget for wire nuts or crimps and a single gang plate or flange location in your rough-in.
4) Can I mount the AI-624 buzzer without cutting into a gang plate?
Yes. Besides the 1-1/4 inch hole in a single gang wall plate, the AI-624 can be flange mounted, which lets you fix it to a panel wall, the inside of an enclosure, or a bracket where no device box is available.
5) Is the AI-624 audio alert indicator a piezo sounder or a mechanical buzzer?
It is a mechanical buzzer, not a piezo. That gives it the lower, harsher continuous tone people associate with door-ajar and request-to-exit annunciation rather than the high pitched chirp of a piezo sounder.
6) Is the Alarm Controls AI-624 suitable for commercial building installs?
Yes, the AI-624 is a commercial grade accessory intended for electronic access control systems, typically wired as the audible annunciator for door position switches, request-to-exit devices, or delayed egress and alarm circuits.
7) Is there more than one version of the AI-624 to specify when ordering?
No options to sort out. The audio alert indicator is a single model, AI-624, with no finish or voltage variants to pick, so the only decisions left are your mounting method and how you splice the leads.
