All other units in the interconnect system will sound an alarm but their red LED’s will NOT flash rapidly. The green LED has two modes of operation. Standby Condition The green LED will be steady on, indicating the presence of AC power. Alarm Condition This smoke alarm is equipped with an alarm memory which provides a visual indication when an alarm has been activated. A flashing green LED indicates the memory condition. The memory will remain activated until it is reset by pushing the test button. In an interconnected installation only the memory of the originating alarm will be activated. TESTING: Test by pushing the test button on the cover and hold it down for a minimum of 2 seconds. This will sound the alarm if the electronic circuitry and horn are working. If no alarm sounds, check the fuse or circuit breaker supplying power to the alarm circuit. If the alarm still does not sound, the unit may have other failure. DO NOT use an open flame to test your alarm, you could damage the alarm or ignite combustible materials and start a structure fire. TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic or low sound coming from your alarm may indicate a defective alarm, and it should be returned for service (see Section 12). 5. NUISANCE ALARMS Smoke alarms are designed to minimize nuisance alarms. Cigarette smoke will not normally set off the alarm, unless the smoke is blown directly into the alarm. Combustion particles from cooking may set off the alarm if the alarm is located close to the cooking area. Large quantities of combustible particles are generated from spills or when broiling. Using the fan on a range hood which vents to the outside (non-recirculating type) will also help remove these combustible products from the kitchen. If the alarm does sound, check for fires first. If a fire is discovered, get out and call the fire department. If no fire is present, check to see if one of the reasons listed in Section 2 may have caused the alarm. 6. MAINTENANCE ALARM REMOVAL IF TAMPER RESIST PIN HAS BEEN USED, REFER TO TAMPER RESIST LOCKING PIN IN SECTION 3 FOR PIN REMOVAL INSTRUCTIONS. You can remove the alarm from the trim ring by rotating the alarm in the direction of the “OFF” arrow on the cover (See Section 3. Figure 4). To disconnect the A.C. power harness, squeeze the locking arms on the sides of the Quick Connector while pulling the connector away from the bottom of the alarm (see Section 3, Figure 3). CLEANING YOUR ALARM. YOUR ALARM SHOULD BE CLEANED AT LEAST ONCE A YEAR. To clean your alarm, remove it from the mounting bracket as outlined in the beginning of this section. You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm. The outside of the alarm can be wiped with a damp cloth. After cleaning, reinstall your alarm and test your alarm by using the test button. Check that the green LED is on. If cleaning does not restore the alarm to normal operation the alarm should be replaced. 7. LIMITATIONS OF SMOKE ALARMS WARNING: PLEASE READ CAREFULLY AND THOROUGHLY •NFPA 72 states: Life safety from fire in residential occupancies is based primarily on early notification to occupants of the need to escape followed by the appropriate egress actions by those occupants. Fire warning systems for dwelling units are capable of protecting about half of the occupants in potentially fatal fires. Victims are often intimate with the fire, too old or young, or physically or mentally impaired such that they cannot escape even when warned early enough that escape should be possible. For these people, other strategies such as protection-in-place or assisted escape or rescue are necessary. •Smoke alarms are devices that can provide early warning of possible fires at a reasonable cost; however, alarms have sensing limitations. Ionization type alarms offer a broad range of fire sensing capabilities but are better at detecting fast flaming fires than slow smoldering fires. Photoelectric alarms sense smoldering fires better than flaming fires. Home fires develop in different ways and are often unpredictable. Neither type of alarm (photoelectric or ionization) is always best, and a given alarm may not always provide warning of a fire. •A battery powered alarm must have a battery of the specified type, in good condition and installed properly. •A.C. powered alarms will not operate if the A.C. power has been cut off, such as by an electrical fire or an open fuse. •Smoke alarms must be tested regularly to make sure the batteries and the alarm circuits are in good operating condition. •Smoke alarms cannot provide an alarm if smoke does not reach the alarm. Therefore, smoke alarms may not sense fires starting in chimneys, wall, on roofs, on the other side of a closed door or on a different floor. • If the alarm is located outside the bedroom or on a different floor, it may not wake up a sound sleep...
