Description	AC Smoke Detector Alarm with Battery Back-up and False Alarm Control
	The Firex 4518 Smoke Alarm is an ionization 120V AC smoke alarm with battery back-up for single or multiple station use. It includes a Quick QuietTM False Alarm Control feature which allows the user to quiet an unwanted alarm for up to 15 minutes. The 4518 has an 85 decibel horn, ramp-up test horn, test switch and separate lighted power and alarm LED indicators; the green ”power on” LED confirms constant AC power and the red LED displays alarm/battery status. The Latching LED feature clearly identifies the smoke alarm that initiated an alarm in an interconnected system with a flashing red LED. The LED will remain flashing until the test button is depressed on that unit. The dust cover eliminates nuisance call-backs by keeping construction dust and debris from causing false alarms. This unit mounts 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. The 4518 is interconnectable with up to 11 other AC/DC smoke alarms and 6 Firex heat, carbon monoxide or smoke and CO combo alarms for a total of not more than 18 Firex devices. When interconnected with other Firex smoke alarms, the unit that initiates an alarm will display a rapidly flashing red LED while the other interconnected alarm LEDs remain extinguished. This Firex unit should be placed in single-family households or in each individual living unit of multiple-family buildings.
