Safety and Security — FAQ
How loud is 120dB compared to everyday sounds?
120dB is equivalent to a thunderclap or chainsaw at close range—loud enough to cause immediate hearing damage with prolonged exposure. For context, normal conversation is 60dB, while a rock concert reaches 110dB. This extreme volume ensures you and neighbors hear the alarm instantly during a break-in.
Will these door alarms work on carpeted floors?
Most wedge alarms work best on hard surfaces like wood or tile. On carpet, the wedge may compress and reduce trigger sensitivity. The TECKNET's silicone base and Securityman's bar design perform better on carpet than basic plastic wedges. For carpeted bedrooms, place a thin rigid board under the wedge for reliable activation.
Can I use these alarms on sliding patio doors?
Standard wedge alarms only work on hinged doors with an under-door gap. For sliding patio doors, you need a bar-style alarm like the Securityman that braces between the door and wall. Some users creatively wedge standard alarms in the sliding track, but this reduces effectiveness and may damage the alarm.
Are door stop alarms legal in hotels and rentals?
Yes, portable door alarms are legal security devices in hotels, Airbnbs, and rental properties. They cause no permanent modification and are specifically designed for temporary installation. However, check lease agreements for any security device restrictions—some landlords prohibit devices that could damage door frames, though wedge alarms pose minimal risk.
How often will I need to replace batteries in non-rechargeable models?
With typical use (testing weekly), a 9V battery lasts 6-12 months. In standby mode, most alarms claim 1-year battery life, but our tests show 8-10 months is realistic. Heavy use or frequent false triggers drain batteries faster. Budget $3-5 annually per alarm for battery replacement, or choose the TECKNET rechargeable model to eliminate this cost.
Can pets trigger these alarms accidentally?
Yes, pets over 15 pounds can trigger pressure-sensitive wedge alarms when leaning against doors. The activation threshold is typically 2-3 pounds of pressure. For pet owners, consider mounting the alarm higher using a custom block, or opt for magnetic door/window sensors instead. The Securityman bar design is less susceptible to pet triggers.
