Installation of Smoke Alarm This smoke alarm should be installed in accordance with NFPA’s Standard 72 (National Fire Protection Association, Batterymarch Park, Quincy, MA 02269) and any local codes that apply. For the AC and AC/DC direct wire smoke alarms use #18 AWG minimum solid or stranded wire. When interconnecting, 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 and heat alarms to a single AC branch circuit. If local codes do not permit, be sure the neutral wire is common to both phases. Architectural Specifications The 4480 shall be 1-3/8” high and 5” wide, powered by a 120V AC, 60Hz source with a 9 volt battery back-up. Nominal sensitivity shall be measured by U.L. at obs. 2.3 ± .95%/ft. A green continuous power on indicator shall be a built-in light emitting diode (LED) in the standby condition; a second red blinking LED shall indicate that a sufficient 9-volt battery back-up is present; when activated, the initiating alarm red LED shall flash while the interconnected alarms remain extinguished. A 70 day low battery signal shall be included. The 484(C) shall be 1-3/16” high and 4-7/8”wide powered by a 120V AC, 60Hz source. Nominal sensitivity shall be measured by U.L. at obs. 2.2 ± 1.2%/ft. and by U.L.C. at obs. 2.2 ± .75%/ft. A power-on indicator shall be a built-in LED which blinks once per minute in the standby condition; when activated, the initiating alarm LED shall flash while the interconnected alarms remain extinguished. The 4480 and the 484(C) shall be rated at no more than 0.5W in standby and have 100% solid state alarm circuits over an input range of 100-130V AC. The alarm shall mount to a single gang box, 4” octagon junction box, or a square-toround drywall ring without screw removal. It shall have a Quick Connect molded harness and pigtail wiring. The 480(C) shall be 1” high and 4” wide powered by a 9V DC battery source. Nominal sensitivity shall be measured by U.L. at obs. 2.2 ± 1.2%/ft. and by U.L.C. at obs. 2.2 ± .75%/ft. 100% solid state alarm circuits over an input range of 6.8-10V DC. A power-on indicator shall be a built-in LED which blinks once per minute in the standby condition and a 30 day low battery signal shall be included. All Firex photoelectric smoke alarms shall be a Styleline designTM and have a photoelectric sensor. Operating temperature range shall be between 40° and 100°F (4°-38°C) and relative humidity range between 10%-93%. The test switch shall electronically activate the chamber to simulate smoke and check for proper operation. The electric horn shall have a level of 85 decibels at 10 feet and all units have a separate mounting bracket. Items 4480, 484, 480 shall meet the requirements of U.L. 217 and items 484(C) and 480(C) shall meet the requirements of U.L.C. S531.
