ULTRA-LOUD BUZZER OPTION

The model SA-1 piezo buzzer is EXTREMELY LOUD.  This is the loudest buzzer that can be operated from 9-12VDC power.   It can be used as an accessory to our other products, or a stand-alone annunciator with buzzer + beacon light.

Because the SPL is 110dB at two feet distance, it is not for every day exposure to the sound. Mounting it up high will keep it away from ears and also broadcast the sound over a wider area.

SOUND LEVEL COMPARISON

Our standard warble buzzer on most of our products is comparable to a smoke detector.  Conversation is almost impossible, and people try to silence the buzzer without delay. The SA-1 Siren by comparison, is in a different league: it is painful to endure, and people will immediately clamp hands over their ears, and /or move away from the siren. 

MODELS

Both models require power and respond to an external contact close.

The SA-1 consists of a piezo-buzzer and strobing LED only. (must be shut off by removing the contact close, or cutting power) 

The SA-2 includes a remote shutoff box so it can be silenced at a bit of distance, and the piezo-buzzer and LED can be located up high. The SA-2 includes a circuit that allows a person to shut off the piezo-buzzer for 30 minutes, while the LED continues to strobe.  We refer to this feature as our “snooze alarm”.
