Product Overview

Kidde FireX Hardwired 120-Volt Smoke Alarm is interconnectable with other hardwired alarms. The front battery pull tab allows battery activation without removing alarm from mounting bracket. The large mounting base makes mounting easier, protects surface paint from dirt and covers imperfections. Pre-stripped wiring harness with easy off cap does not require stripper tool. Tinned strands increase conductivity and wire nut grip. Battery run down protection will shut down alarm memory when AC power is not present, reducing low battery chirp.
