Alarm Controls System Accessories - TS-42 Mounted Wall Buzzer

The TS-42 runs on 12 VDC and draws 25 mA. That load is small enough to run off the same 12 VDC supply feeding most access control panels or door strikes, but size the supply for the strike's inrush plus this 25 mA.

Yes. The TS-42 is an LA32 buzzer factory-mounted on a single gang wall plate, so it drops onto any standard single gang box or mud ring. Nothing is cut or drilled on site; the plate is the finished cover.

Sound output is 80 dB measured at 3 feet. That carries well at a reception counter, a nurse station, or a small back office where someone is within a few feet of the plate. For a noisy loading dock or a long corridor, pick a higher output sounder instead.

It comes terminated with 12 inch wire leads, so you splice to your 12 VDC feed and switched leg inside the gang box. Leave enough service loop behind the plate; 12 inches is short if the box is deep and crowded with other conductors.

Choose based on where it goes. The TS-42 is the LA32 already mounted on a single gang stainless plate, which is what you want for a finished wall location at a desk or entry. If the sounder is going inside a cabinet, panel enclosure, or a door frame where you just need a hole for it, a loose sounder is the better fit since you are not paying for a plate you will not show.

Yes. It is a 12 VDC, 25 mA load with flying leads, so any dry contact relay output on an access panel, timer, or door position switch can switch it by breaking the positive leg. The current draw is well within a typical panel auxiliary relay rating.

The wall plate is stainless steel, which lines up with the brushed stainless single gang plates used on most commercial push buttons and request-to-exit stations, so it blends into a run of existing devices on the same wall.

It is a commercial-rated device, built for access control and entry annunciation in offices, schools, healthcare, and multi-family entries rather than as a residential doorbell.
