User manual FIRST ALERT SA320

[. . . ] USER'S MANUAL SMOKE ALARMS All First Alert® and BRK® Smoke Alarms conform to regulatory requirements, including UL217 and are designed to detect particles of combustion. Smoke particles of varying number and size are produced in all fires. Ionization technology is generally more sensitive than photoelectric technology at detecting small particles, which tend to be produced in greater amounts by flaming fires, which consume combustible materials rapidly and spread quickly. Sources of these fires may include paper burning in a wastebasket, or a grease fire in the kitchen. [. . . ] Not responding to an alarm can result in property loss, injury, or death. The Silence Feature on these units can temporarily quiet an unwanted alarm for up to 15 minutes. To use this feature, press the Test/Silence button on the cover. If the unit will not silence and no heavy smoke is present, or if it stays in silence mode continuously, it should be replaced immediately. RECOMMENDED LOCATIONS FOR SMOKE ALARMS Installing Smoke Alarms in Single-Family Residences The National Fire Protection Association (NFPA), recommends one Smoke Alarm on every floor, in every sleeping area, and in every bedroom. In new construction, the Smoke Alarms must be AC powered and interconnected. See "Agency Placement Recommendations" for details. For additional coverage, it is recommended that you install a Smoke Alarm in all rooms, halls, storage areas, finished attics, and basements, where temperatures normally remain between 40° F (4. 4° C) and 100° F (37. 8° C). Make sure no door or other obstruction could keep smoke from reaching the Smoke Alarms. More specifically, install Smoke Alarms: · On every level of your home, including finished attics and basements. · Inside every bedroom, especially if people sleep with the door partly or completely closed. · In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit in each. If a hall is more than 40 feet long (12 meters), install a unit at each end. · At the top of the first-to-second floor stairway, and at the bottom of the basement stairway. Specific requirements for Smoke Alarm installation vary from state to state and from region to region. Check with your local Fire Department for current requirements in your area. It is recommended AC or AC/DC units be interconnected for added protection. SILENCING THE LOW BATTERY WARNING This Silence Feature can temporarily quiet the low battery warning "chirp" for up to 8 hours. Press the Test/Silence button on the Alarm cover until you hear the acknowledge "chirp". Once the low battery warning "chirp" silence feature is activated, the unit continues to flash the green light once a minute for approximately 8 hours. After 8 hours, the low battery "chirp" will resume. Replace the batteries as soon as possible; this unit will not operate without battery power! LATCHING FEATURE Alarm Latch is activated after an Alarm is exposed to alarm levels of smoke. After smoke levels drop below alarm levels, the Red LED will begin flashing 2 seconds on, 2 seconds off unless reset by test/silence button. [. . . ] You must test the unit weekly to ensure your continued protection. Smoke Alarms cannot prevent or extinguish fires. They are not a substitute for property or life insurance. The unit should be replaced immediately if it is not operating properly. [. . . ]
