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!

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.
