Direct Wire 120V Smoke Alarm with Battery BackUp by FireX Kidde I4618 FADC

The Firex 4618 Smoke Alarm is an ionization 120V AC smoke alarm with battery back-up for single or multiple station use. It includes a False Alarm Control(TM) feature which allows the user to quiet an unwanted alarm for up to 15 minutes. The 4618 has a front loading battery door, 85 decibel horn, test switch and dual purpose LED indicator; constant green ”power on” LED confirms AC power is present and the flashing red displays alarm/battery status. Our unique PowerLink(TM) Tab is designed to allow the smoke alarm to be shipped with the battery already installed. It keeps the door from closing until installation, which prevents the battery from draining prematurely. The installer simply removes the PowerLink(TM) Tab, closes the door and tests the unit. This results in a faster installation time. 

The latching LED feature clearly identifies the smoke alarm that initiated an alarm in an interconnected system with a constantly illuminated red LED. The LED will remain lit until the test button is depressed on that unit.

This smoke alarm 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 4618 is interconnectable with up to 11 other compatible Firex smoke alarms and as many as 6 Firex heat alarms for a total of not more than 18 interconnected devices. This Firex unit should be placed in single-family households or in each individual living unit of multiple-family buildings.

Installation of Smoke Alarm
This smoke alarm should be installed in accordance with the NFPA’s Standard 72 (National Fire Protection Association, Batterymarch Park, Quincy, MA 02269) and any local codes that apply.

When interconnecting, use #18 AWG minimum solid or stranded wire. Maximum wire length between any two is 1,500 feet for #18 AWG or 4,000 feet for #14 AWG (20 OHMS loop resistance).

DO NOT connect to any other type or model of heat or smoke alarm. Connect smoke or heat alarms to a single AC branch circuit. If local codes do not permit, be sure the neutral wire is common to both phases.
