Extremely loud 12 VDC car alarm siren. Distinctive siren pattern cycles through six different sounds every thirty seconds. Overall dimensions: 3.20" x 2.85 x 3.75" high including mounting bracket. Two 66" wire leads. 2.55" mounting centers on adjustable metal base.
There is more than likely Machinery running that drowns out our Heavy Duty 24 VAC Clapper type Door Bell. I purchased one of these Alarms and inserted a Diode and a Capacitor to create a Half Wave 12 VDC Power Supply. When the 24 VDC Door Bell rings, the Alarm now sounds at the same time. The sound is loud enough now to even be heard in the Office with the door shut and the AC running. Perfect!

Awesome LOUD speaker for any alarm usage. Operates as low as 2Vdc but not as loud, though still loud!

Alert Alarm for pump operation and plumbing malfunction.

This is an excellent alarm. I used it with a 12 V power pack connected to the line going to a submersible water pump in a well pit for a farm house. It goes on for a few seconds every time the pump goes on to fill the pressure tank and you can even hear it through the heavy covers under 3 feet of snow in the winter! If there's a problem with a water leak, the pump will run often and the changing sound will alert you to this. There was an issue where a pipe nipple was failing and it was spraying water out causing the pump to cycle on and off over and over 24 hours a day. This will never happen again with this safeguard which saves the thousand dollar plus expense of having to replace an underground pump.
