4-Pack Hardwired Smoke Detectors with Ionization Sensors

About This Item

• Easy Installation – No Tools Required for Wiring: The front battery pull tab allows battery activation without removing the alarm from the mounting bracket. The large mounting base makes installation easier, protects surface paint from dirt, and covers imperfections. The pre-stripped wiring harness with easy-off cap does not require a stripper tool. Tinned strands increase conductivity and wire nut grip for secure connections.

• Fewer Callbacks – Test/Hush Button & Dust Cover: The large centrally located Test/Hush alarm control button makes testing and silencing simple. The dust cover protects the sensor from contaminants during construction, reducing nuisance alarms.

• User-Friendly Features – Front Loading Battery & Backup: The easy-access front loading battery door simplifies battery replacement. Battery backup provides protection in case of power failure. Interconnectable with up to 24 devices (of which 18 can be initiating), including smoke, CO, and heat alarms. See user's guide for complete instructions.

• Alarm Memory & Temperature Range: Alarm memory flashes the red LED to indicate which unit was the initiating alarm in an interconnected system. Temperature Range: 40°F to 100°F.

• Tamper-Resist Locking Feature: The tamper-resistant locking feature deters alarm theft, providing added security and peace of mind.
