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!

It matched the ad. It was simple to install! And the horn was great as we expected!

No more prank alarm after installing this

This was great for the job. Less than having a professional install it was

When pulled deliberately or by accident, it sends a loud signal.
