Stopper ® II is intended to be used in areas where the incidence of
false fire alarms from manual pull stations is high or has proven to
be a serious problem. Any disadvantage of this device is more than
balanced when one considers the consequences of false fire alarms,
especially if fire service personnel and equipment are responding to
a false fire alarm when they are needed for a real fire somewhere
else. Add this to the disruption of the facility when false alarms
occur. If you have, or may have a problem with false fire alarms or
physical weather damage to your fire alarm activation devices, the
Stopper II could prove invaluable.
