Safety and Security β FAQ
How long do door alarm batteries typically last?
9V batteries provide 6-12 months in standby mode, activating 20-30 times before depletion. Rechargeable units last 3-6 months per charge depending on alarm frequency. Remove batteries during extended non-use.
Will these alarms damage my floors or doors?
Quality rubber and silicone bases prevent scratching on all floor types. The wedge design distributes pressure evenly, leaving no marks on doors when used correctly. Avoid dragging the unit across delicate surfaces.
Can pets trigger false alarms accidentally?
Pets under 40 pounds rarely generate enough pressure to activate properly-calibrated sensors. Place wedges in low-traffic areas or use bar-style alarms for pet-friendly homes to minimize accidental triggers from play.
Are door alarms effective against determined intruders?
120dB+ sirens create immediate attention and panic, deterring most opportunistic burglars. They provide 10-30 seconds of warning for escape or calling 911. Combine with physical barriers for maximum entry delay.
Do these work on sliding glass doors?
Standard wedge alarms fit some sliding doors but bar-style designs like Securityman work better. Measure your track gap before purchasing. Most effective when placed in the sliding track itself to block movement physically.
Can I use multiple alarms on one door?
Yes, placing two wedges at different points increases security redundancy. One at the bottom and a bar-style unit mid-door creates dual-layer protection. This ensures one activates even if another is discovered and disabled.
