Product Overview
This protective cover has been helping to stop false fire alarms around the world for
more than 30 years, without restricting legitimate alarms. All models offer excellent
protection against physical damage (both accidental and intentional) and several
against severe environments both inside and out. It is ideal for schools, colleges,
hospitals, nursing homes, stores, hotels and public buildings of almost every kind
where there is a threat of false alarms.
how it works
Stopper II consists of a clear, tamperproof, tough polycarbonate shield and frame, but
the line includes models with the option of a piezo horn, spacer, Form “C” dry relay
contact and gaskets. The cover accommodates most manual pull stations. When the
Stopper II with horn is lifted to gain access to the protected alarm, a piercing selfcontained 95 or 105 dB warning horn (at one foot) sounds. Immediate attention is
drawn to the area and a prankster will either run or be caught. The cover is connected
to the frame by a cable. When the cover is lifted, it drops off of the frame and a horn
will sound (models with horn) until the cover is snapped back onto the frame or for the
life of the battery.
