Extremely loud piezo-buzzer for unusual situations when maximum volume is necessary.
ULTRA-LOUD BUZZER OPTION
The Siren alarms piezo are 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 from damaging 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 extremely difficult, 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
The Siren alarms can be either line powered, or battery powered. (designated with the suffix ‘B’ ) The standard enclosure size is 5×5 inches for all models.
The SA-1 consists of a piezo-buzzer and strobing LED in a 5×5 enclosure. The alarm is triggered by a contact close, and must be shut off by removing the contact close, or cutting power. If powered by 9V battery, then there is a circuit board inside that gives a low battery alert.
The SA-2 includes a remote shutoff box so it can be silenced at a distance. And the remote shutoff button box allows the piezo-buzzer and LED box to be located up high away from people. 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”.
