The biggest problem with Mechanical Sirens is not the ability to make sound, Itís the ability to control them. If you fix that you tame the monster.
Our Mechanical controller was designed by us, made by us and sometimes installed by us. It is a proven technology that has been in the field for over 15 years. Since the beginning there has been only 2 failures and not one false activation.
It takes only 5 wires to wire the controller in. These are; 2 for power in, two for the controller and one for earth ground. It is supplied in 110 or 220 volt operation.
The standard model uses HIGH SPEED Whelen protocol for operation and is easily interfaced into Whelen systems. Other protocols for control are available.
