Don't let burglars sneak in through your windows! The 95dB Window Alert is an easy-to-install window security system that alerts you instantly with a loud, 95dB alarm if windows are bumped or broken, sounding the window alarm for 45 seconds before resetting automatically, ample time to frighten away even the bravest burglar. You'll appreciate the added security this window alarm provides from window tampering and breakage. The 95dB Window Alert installs easily using the included mounting tape. Just slide the glass-break sensor's switch to the ON position for instant security. The battery is pre-installed. A 95dB Entry Alert is also available. This battery-operated door alarm sounds a loud 95dB tone when its magnets separate. If you prefer a motion detector-triggered alarm, the 105dB Motion Alert with Keypad acts as a programmable burglar alarm that has a built-in motion sensor that triggers the extra-loud alarm when someone passes through it.
