    MODEL 2975CN, 2975LCN SMOKE & FIRE ALARM WITH SILENCE FEATURE AND ALARM ORIGINATION 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: Smoke Alarm Limitations And Functions

    SMOKE ALARM LIMITATIONS AND FUNCTIONS ® 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: Recommended Location Of Alarms

    RECOMMENDED LOCATION OF ALARMS • Locate the first smoke alarm in the immediate area of the bedrooms. Try to protect the escape route as the bedrooms are usually farthest from an exit. If more than one sleeping area exists, locate additional smoke alarms in each sleeping area. If a hall is more than 40 feet (12 meters) long, install a smoke alarm at each end.

  • Page 4: Avoid These Locations

    AVOID THESE LOCATIONS • the garage – products of combustion are produced when you start your vehicle. • near appliances or areas where normal combustion regularly occurs (kitchens, near furnaces, gas hot water heaters). Use smoke alarms with photoelectric sensors or smoke alarms with Silence Feature for these areas.

  • Page 5: Mounting Instructions

    MOUNTING INSTRUCTIONS Attach the mounting bracket in the proper location on the wall or ceiling (screws and anchors provided). To activate 9 volt battery and alarm, hold the battery, pull and remove the PULL-TAB. Confirm that the entire PULL-TAB has been completely removed. Discard PULL-TAB. Push and twist the alarm clockwise onto the mounting bracket.

  • Page 6: Silence Feature

    NUISANCE ALARM SILENCE FEATURE: This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the smoke alarm. The smoke alarm Silence Feature is activated by pushing and releasing the Silence button on the smoke alarm cover while in alarm condition.

  • Page 7: Operational Summary

    WHAT TO DO WHEN THE ALARM SOUNDS o Leave immediately by your plan of escape. Every second counts, so don't waste time getting dressed or picking up valuables. o In leaving, don't open any inside door without first feeling its surface. If hot, or if you see smoke seeping through cracks, don't open that door! Instead, use your alternate exit.
