Know from Anywhere: When one smoke detector is triggered, all wireless smoke detectors will sound, so you and your family can hear the alarm from anywhere in your home; an intelligent locating function allows you to quickly locate the source of the fire, giving you every extra life-saving second to control the fire or evacuate

Wide Coverage for Full Home Protection: Featuring a relay function that extends transmission range, this radio-interlinked smoke detector can be interconnected with up to 24 wireless alarms to create a smart home network with no blind spots, even on different floors or in the basement and garage

Easy to Install, Interconnect, and Operate: This mini smoke alarm can be quickly installed onto any wall or ceiling without hardwiring; simply press the test/silence button to interconnect your wireless smoke detectors (the alarms in one multi-pack have already been interconnected); easy to test the alarm regularly or silence false alarms (e.g., cooking fumes) with a simple push

5-Year Replaceable Battery & Self-Check: The battery operated smoke detector supports 5-year continuous use and can be easily replaced by yourself; a low-battery warning to let you clearly know when it’s time to replace the battery for safety

Fits Right In: Mini size alarm measuring just 3.1 × 1.9 in (78 × 48 mm) and with hidden mounting bracket; low-profile design makes it an unobtrusive addition to any home décor
