Exit Stopper Door Alarm with 110dB Siren - Easy Door Alert

Our review of the Exit Stopper Door Alarm finds it best suited for facilities that need a simple, loud alert to prevent unauthorized exits or entries through emergency doors. The single biggest reason to buy is its uncomplicated, reliable alarm function: the unit emits a powerful 110dB siren that immediately notifies staff when a protected door opens, and the kit includes the battery and mounting hardware so it works out of the box. Installation is straightforward for anyone comfortable with basic mounting, and the compact design keeps the alarm discreet while remaining effective.

Key Features

• 110dB Alarm: Produces a loud siren level to alert personnel and deter unauthorized door use in busy or noisy environments.
• Adjustable Loudness: Allows tuning of the alarm sound level to match the environment while maintaining a clear audible alert.
• Easy Installation: Main unit mounts to the frame and the magnet attaches to the door, so setup is quick without special tools.
• Versatile Design: Flexible cable and compact footprint let the alarm be positioned on many door types including emergency and warehouse doors.
• Complete Kit: Ships with the alarm main unit, magnet, 9V battery and mounting hardware for immediate use.
• Battery Powered: Runs on a 9V battery for consistent operation without wiring to building power.

Who It's For

The Exit Stopper Door Alarm is ideal for small businesses, warehouses, bars, and offices that need a low-complexity solution to monitor emergency or back doors. Facilities with staff who need instant audible alerts when a door opens will appreciate the loud siren and the included mounting hardware that makes deployment fast.

It is less suited to environments that require networked monitoring, remote alerts, or integration with building access control systems; those users should look for a wired or smart alarm with logging and remote notifications instead.
