Page 1 MODEL 976LR SMOKE & FIRE ALARM WITH SILENCE FEATURE READ ALL INSTRUCTIONS This smoke alarm uses an extremely small amount of a radioactive element in the ionization chamber. Do not tamper with radioactive sealed source or try to repair the smoke alarm yourself.
Page 2 There are three basic smoke alarm types: IoPhic , Ionization and Photoelectric. ®  IoPhic is an ionization alarm containing a patent-pending Universal Smoke Sensing Technology. IoPhic ® ® alarms are very effective at detecting fast flaming fires and also respond very quickly to slow smoldering fires - up to 87% faster than the maximum allowable alarm limit (UL217 Smoldering Smoke Test on 5/26/2010, Underwriters Laboratories Project #09CA38078).
Page 3 • Locate at least one smoke alarm on every floor level. • Locate a smoke alarm in any area where a smoker sleeps or where electrical appliances are operated in sleeping areas. • Smoke, heat and other combustion products rise to the ceiling and spread horizontally. Mounting the smoke alarm on the ceiling in the center of the room places it closest to all points in the room. Ceiling mounting is preferred in ordinary residential construction. However, in mobile homes, wall mounting on an inside partition is preferred to avoid the thermal barrier that may form at the ceiling.
Page 4 • in areas of turbulent air such as air returns or heating and cooling supply vents, smoke alarms shall not be located where airflow prevents smoke from reaching the alarms. • in extremely dusty, dirty or insect-infested areas. Loose particles interfere with smoke alarm operation. • in areas where temperature may fall below 40 F (4.4 C) or rise above 100 F (37.8 • closer than 1 foot (0.3m) from fluorescent lights, electrical "noise" and flickering may affect the alarm's operation. • closer than 3 feet (0.9m) horizontal path from the tip of the blade of a ceiling suspended (paddle) fan. • on a poorly insulated ceiling or exterior wall (mount smoke alarm on an inside wall). THIS SMOKE ALARM WILL NOT WORK WITHOUT A GOOD BATTERY PROPERLY INSTALLED. THE SMOKE ALARM SHOULD BE TESTED WHEN INSTALLED AND THEN TESTED WEEKLY AFTER THAT.
Page 5 OPERATION, TESTING & MAINTENANCE OPERATION: The smoke alarm is operating once the battery power is connected by removing the PULL-TAB. When products of combustion are sensed, the alarm sounds a loud alarm which continues until the air is cleared. This alarm incorporates the NFPA recognized horn signal for evacuation. During alarm mode, the horn produces three long beeps followed by a two second pause and then continually repeats. READY/ACTIVE CONDITION: The red LED blinks on once approx. every 40-45 seconds to indicate the alarm is properly functioning. ALARM CONDITION: The red LED blinks on once approx. every second and the alarm emits a loud, pulsating alarm sound. NUISANCE ALARMS: The smoke alarm is designed to minimize nuisance alarms.
Page 6 NOTE: If the Test button is pressed and held during the Silence mode, the smoke alarm will be tested normally. Upon the release of the Test button, the Silence mode will be restarted. Before using the alarm Silence Feature, identify the source of smoke and be certain that safe conditions exist. Clean the smoke alarm at least once a month to remove dust, dirt, insects or debris. Using a soft brush or wand attachment to a vacuum cleaner, vacuum all sides and cover of smoke alarm. Be sure all the vents are free of debris. If the smoke alarm is false alarming and cannot be restored to normal operation, the smoke alarm should be replaced. BATTERY REPLACEMENT The smoke alarm uses a 9 Volt battery. The battery should last for at least one year under normal operating conditions. The smoke alarm has a low battery indicator, an audible beep or chirp. It will operate at approx. 40 second intervals for a minimum of 7 days. When this indication occurs, replace the battery with an Alkaline type (Energizer #522, Duracell #MN1604) or Lithium type (Ultralife U9VL-J) from your local retailer.
