The BS-413 alarm siren is of robust design and can be used with conventional burglar alarm panels such as the BS-468. It has a red beacon that blinks when the siren is activated and a piezo speaker that produces a sound level of 115dB at 1 meter.
The incorporated tamper mechanism protects the siren from unauthorized access when the cables are cut, the cover is removed or when the siren is unmounted from the wall.
BS-413/DM is an external siren cover.
