About Stopper Covers & Alarm Guards

Protect your fire alarm, thermostat, keypad or security alarm from unintended tripping, vandalism and accidental damage with a stopper cover or alarm guard. Busy warehouses, plant floors and office spaces can often be the scene of an unexpected traffic jam, which just might lead to accidental contact with these important consoles and devices. Don’t risk the fallout should someone fall into the alarm or unknowingly reset the thermostat—not only will you lose all kinds of productivity, in the end, it will hurt the bottom line. Tough metal cages and strong, transparent plastic and Plexiglass covers are available. For more safety and protection, shop for safety alarms, horn strobe alarms and fire alarm components like smoke and carbon monoxide detectors.
