Autonomy Siren Beacon with Battery BS-413 12V 1.3Ah 921413000
The BS-413 alarm siren is a sturdy construction used in conjunction with conventional wiring alarm panels, such as the BS-468 panel.
It has a red light that flashes when the siren is activated and a piezoelectric membrane, which produces sound with an intensity of 115dB at 1 meter.
Inside the device there is a mechanism (Tamper) which activates the siren if someone tries to cut the wires or remove the cover or take it off the wall.
If the battery is not connected then the siren produces a one tone sound every 1 second while if the battery does not work properly then every 12 hours the siren produces a 3 ton sound.
