Technical Spec

The Firex 120V AC ionization smoke alarms have an 85 decibel horn, test switch and a lighted power/alarm LED indicator; the LED flashes once per minute to confirm AC power. When in alarm, the LED flashes rapidly once per second. When interconnected with other Firex smoke alarms, the unit that initiates an alarm will display the rapidly flashing LED while the other interconnected alarm LEDs remain extinguished. The 428 includes a False Alarm ControlTM feature which allows the user to quiet an unwanted alarm for up to 15 minutes.

These units mount to any single or 4” octagon junction box or square-to-round drywall ring and has 8” long pigtails with a Quick Connect harness for permanent connection. Firex AC smoke alarms are for single or multiple station use and interconnect with other Firex smoke alarms (see Technical Specifications on the back side for interconnect quantities and compatibility). This Firex unit should be placed in single-family households or in each individual living unit of multiple-family buildings.
