Kidde Firex Hardwired Smoke Detector with Ionization and Photoelectric Dual Sensors

The Kidde PI2010 is a 120-Volt AC, wire-in smoke alarm with 9-Volt battery backup. This smoke alarm functions as a stand-alone unit or in an interconnected system. The Kidde PI2010 features Hush, allowing you to quickly silence nuisance alarms and also includes a tamper resist features that deters tampering and theft. The PI2010 includes a quick connect power harness that allows for quick and easy installation. This smoke alarm combines both photoelectric and ionization sensors. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms.|Interconnect interconnects with up to 24 Kidde devices on one wiring network of which 18 can be initiating|Ionization sensor may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms|Photoelectric sensor may detect visible particles (associated with smoldering fires) sooner than ionization alarms|Battery backup (9-Volt battery included) provides continuous protection even during power outages|Tamper resistant deters from tampering or theft|Hush feature temporarily silences nuisance alarms|Check with your state and local fire and building/safety codes for specific information regarding smoke and carbon monoxide alarms|Smoke detector utilizes ionization and photoelectric sensors to detect fire hazards and sounds an 85 db alarm when a hazard is detected
