Window Door Siren

Notifies you if unauthorized doors or windows are opened by emiting a loud siren.

With the alarm switch in the "ON" position, the unit will alert you by emitting a loud siren whenever the speaker unit and the smaller magnet unit are separated by about one inch or more. The unit will continue to sound until you switch the unit to the "OFF" position or return the two units to a side by side position. Batteries are included and the unit is ready to use when you receive it.
