  • What's Included
  • Keep your home safe from smoke and fire hazards with Universal Security Instruments' IoPhic Home Hardwired Smoke and Fire Alarm. This 2-In-1 alarm is a hardwired wall, or ceiling, mounted alarm system equipped with Microprocessor Intelligence temperature control, humidity control, and false alarm control technology to provide consistent alarm sensitivity and performance without interference from common nuisance alarms such as dust, debris, paint fumes, shower steam, cooking smoke, and household chemicals and cleaners.

    The 2-In-1 alarm system can also be interconnected with up to 24 other similar alarm systems--so when one alarm goes off on the other side of the house, all interconnected alarms will alert you to the presence of smoke or fire. When it comes to these hazards, small or big, false or true, early detection and warning can give you the few seconds needed to get to safety.

    The alarm that originally detects the presence of smoke and,or, fire can be found by simply silencing an alerting alarm and pressing the Test/Silence button to sound the original alarm. The alarm emits a loud 85 dB audible alert that can be heard easily and informs you where the danger is coming from within the home.

    The alarm's interconnectivity, false alarm control, temperature control, and loud sound offers you value and quality for protecting yourself, your home, and loved ones.
