1. Smoke Alarm: What To Do When The Alarm Sounds The smoke alarm pattern is three long beeps with voice “Fire!,” a 1.5 second pause, and three long beeps repeating. The red LED blinks in time with the alarm pattern only on the alarm(s) that detected the hazard (initiating alarm). The smoke alarm takes precedence when both smoke and carbon monoxide are present.
2. Carbon Monoxide Alarm: What To Do When The Alarm Sounds The carbon monoxide (CO) alarm pattern is four quick beeps with voice “Warning! Carbon Monoxide” repeating every 5 seconds. The red LED blinks in time with the alarm pattern. After 4 minutes in CO alarm the alarm pattern and voice will only occur every 60s. warning: Actuation of your CO alarm indicates the presence of carbon monoxide (CO) which can KILL YOU. IF THE ALARM signal sounds: 1) Operate the Test/Hush® button.

5. Introduction, Product Features And Specifications Introduction This alarm detects products of combustion using a multi-criteria optical sensor and carbon monoxide using an electrochemical cell. Many times throughout this User Guide, we will refer to Carbon Monoxide as “CO.” Ten (10) years after the unit was installed, this unit will automatically alert you that it is time to replace the unit. This is called “End of Unit Life” mode. See Troubleshooting Guide.
6. Limitations Of Smoke And Carbon Monoxide Alarms Warning: please read carefully and thoroughly •• 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. •• There are situations where a smoke alarm may not be effective to protect against fire as stated in the NFPA Standard 72.
Warning: Please read carefully and thoroughly •• IMPORTANT: This alarm is designed to detect carbon monoxide gas from ANY source of combustion. It is NOT designed to detect any other gas. CAUTION: This alarm will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. Never restart the source of a CO problem until it has been fixed.
7. Recommended Locations For Smoke And Carbon Monoxide Alarms •• Locate smoke alarms in all sleeping areas. Try to monitor the exit path as the bedrooms are usually farthest from the exit. If more than one sleeping area exists, locate additional alarms in each sleeping area. •• Locate additional alarms in stairways, because stairways act like chimneys for smoke and heat. •• Locate at least one alarm on every floor level. •• Locate an alarm in every bedroom.
NFPA 72 states: “Smoke alarms in rooms with ceiling slopes greater than 1 ft in 8 ft (.3m in 2.4 m) horizontally shall be located on the high side of the room.” NFPA 72 states: “A row of detectors shall be spaced and located thin 6 feet of appliances ANYWHERE within 3 ft (0.9m) of the peak of theALONG ceiling measured horizontally.” THIS BOLD SURFACE within 6 feet of appliances Locations permitted for smoke alarms and smoke detectors on tray-shaped ceilings.
•• For mobile home installation, select locations carefully to avoid thermal barriers that may form at the ceiling. For more details, see MOBILE HOME INSTALLATION section. •• When mounting an alarm on the ceiling, locate it at a minimum of 4” (10 cm) from the side wall. •• When mounting the alarm on the wall, use an inside wall with the top edge of the alarm at a minimum of 4” (10 cm) and a maximum of 12” (30.5 cm) below the ceiling.
8. Locations To Avoid (See Figures 7-A, 7-B, & 7-C) •• In the garage. Products of combustion are present when you start your automobile. •• Normal cooking may cause nuisance alarms. If a kitchen alarm is desired, it should have an alarm silence feature and should not be installed within 6 ft of cooking appliances. •• Do not install within 6 ft of heating appliances. •• Less than 4” (10cm) from the peak of an “A” frame type ceiling.
9. Wiring / Installation / Activation Battery pull tab NOTE: To avoid false low battery chirping pull out the battery pull tab first, before connecting AC power. Wiring Requirements •• This alarm should be installed on a UL Listed or recognized junction box. All connections should be made PULL OUT TAB TO ACTIVAT E BATTERY SEE USER GUIDE FOR ADDITION AL INFORMA TION Figure 9-A by a qualified electrician and all wiring used shall be in accordance with articles 210 and 300.3(B) of the U.S.
Wiring Instructions for AC Quick Connector Harness CAUTION: Turn off the main power to the circuit before wiring the alarm. •• For alarms that are used as single station, DO NOT CONNECT THE RED WIRE TO ANYTHING. Leave the red wire insulating cap in place to make certain that the red wire cannot contact any metal parts or the electrical box. •• When alarms are hardwire interconnected, all interconnected units must be powered from a single circuit.
NOTE: AC power should be turned off at this stage. •• After selecting the proper location for your alarm, and wiring the AC QUICK CONNECTOR harness as described previously, attach the mounting bracket to the electrical box. To ensure aesthetic alignment of the alarm with the hallway, or wall, the “A” line on the mounting bracket should be parallel with the hallway when ceiling mounted, or horizontal when wall mounted.
Tamper Resist Features To make your alarm tamper resistant, two tamper resist features have been provided. The first is used to discourage removal of the alarm while the second is for the battery. Smoke Alarm Tamper Resist To activate the mounting bracket tamper resist feature break off the four posts in the square holes in the trim ring (see figure 9-D). When the posts are broken off, the tamper resist tab on the base is allowed to engage the mounting bracket.
To activate the battery carrier tamper resist feature, remove the unit from the mounting bracket, disconnect the AC quick connector and locate the small cut-out in the middle of the label on the back of the unit. With a small screwdriver, or similar tool, slide the switch towards the “LOCK” position as shown on the label(see Figure 9-F). The tamper resist feature is now active and the battery carrier can not be opened until the tamper resist feature is deactivated.
10. Operation And Testing Operation The alarm is operating once it is activated and testing is complete (see “TESTING” below). When products of combustion (smoke or CO) CO alarm sensor response times At 70 PPM, the unit must alarm within 60-240 minutes. At 150 PPM, the unit must alarm within 10-50 minutes. At 400 PPM, the unit must alarm within 4-15 minutes. are sensed, the unit sounds a loud alarm with voice messages. See Sections 1 and 2 for alarm signal descriptions.
11. Recognizing Nuisance Alarms Smoke Nuisance Hush®: If you know why the alarm is sounding, and you can verify that it is not a life threatening situation, you can push the button on the initiating unit to silence the alarm for 8-10 minutes. If the smoke is not too dense, that unit, and all interconnected units will silence. After the Hush® period, the smoke alarm will automatically reset and sound the alarm if particles of combustion are still present.
12. Battery Backup This alarm is powered with AC power, but also contains a replaceable 9V backup battery located in a convenient front load battery compartment. Under normal conditions, a fresh battery should last at least one year. NOTE: Constant exposure to high or low humidity or temperatures may reduce battery life. WARNING: THE ALARM IS SEALED AND THE COVER IS NOT REMOVABLE! Low Battery This alarm is equipped with a low battery monitor circuit.
13. General Carbon Monoxide (CO) Information Carbon monoxide (CO) is a colorless, odorless, and tasteless poison gas that can be fatal when inhaled. CO inhibits the blood’s capacity to carry oxygen. Possible Sources of CO Inside your home, appliances used for heating and cooking are the most likely sources of CO. Vehicles and other combustion engines running in an attached garage and using a charcoal/gas grill or hibachi in an enclosed area are all possible sources of CO.
Verify that the color of flame is blue on pilot lights and burners. An amber or orange flame is a sign that the fuel is not burning completely and may be releasing CO. Teach all household members what the alarm sounds like and how to respond. Fire Departments, most utility companies and HVAC contractors will perform CO inspections. Some contractors may charge for this service. It’s advisable to inquire about any applicable fees prior to having the service performed.
14. Cleaning Your Alarm Your Alarm Should be Cleaned at Least Once a Year 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. Use only water to dampen the cloth, use of detergents or cleaners could damage the alarm.
15. Good Safety Habits Develop and Practice a Plan of Escape Prepare and practice a home escape plan twice a year, including drills at night. Know two ways out of every room (door & window) and identify a meeting place outside the home where everyone will gather once they have exited the residence. When two people have reached the meeting place, one should leave to call 911 while the second person stays to account for additional family members.
Fire Prevention Never smoke in bed or leave cooking food unattended. Teach children never to play with matches or lighters! Train everyone in the home to recognize the smoke alarm pattern and to leave the home using their escape plan when it’s heard. Know how to do “Stop, Drop and Roll” if clothes catch on fire, and how to crawl low under smoke. Install and maintain fire extinguishers on every level of the home and in the kitchen, basement and garage.
California State Fire Marshal Early warning fire detection is best achieved by the installation of fire detection equipment in all rooms and areas of the household as follows: A smoke alarm installed in each separate sleeping area (in the vicinity, but outside the bedrooms), heat or smoke detectors in the living rooms, dining rooms, bedrooms, kitchens, hallways, attics, furnace rooms, closets, utility and storage rooms, basements and attached garages. FCC This device complies with part 15 of the FCC Rules.
16. Service And Warranty Ten-Year Limited Warranty Kidde warrants that the enclosed alarm (excluding the battery) will be free from defects in material and workmanship or design under normal use and service for a period of ten years from the date of purchase.
