Does the Job
Easy to install, great quality thick durable plastic as described, and the alarm if activated; will get your attention.It’s not a “one size fits all” fire alarm pull stations; we made some modifications and made it work in the space we had.This is a great cover to use in the prevention of false alarms happening, a great investment for commercial properties!

Stop people from falsely pulling fire alarm
Excellent way to stop people from falsely pulling the fire alarm. Working in Long Term Care, we had a situation where someone was pulling fire alarm multiple times daily. Easy to install, loud alarm startles

The alarm is extremely loud but mounting clearance can be difficult in tight spaces.

Great false alarm preventer
Made of thick clear plastic. Easy to Install over existing fire alarm pull stations to give a pre-alarm before actual pull station is activated. Makes loud noise that will get noticed and deter someone from pulling fire alarm.

Awesome
Great product. Someone mentioned the magnet is very strong….. there are no magnets in this device. It snaps into place using nothing more than friction. Loud, for kids looking for the effect of an alarm in the school, this does it for them without alerting the fire department. This is a great product and prevents many false alarms.

These work!
These are excellent deterrents that help to cut down on false alarms. We used them in our 400 room property to help prevent kids from pulling the alarms. The initial noise when the plastic front is lifted tends to send the kids running. Well worth every penny spent
