OPERATION, TESTING & MAINTENANCE OPERATION: The alarm is operating once the AC power is connected and turned on. 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 beeps followed by a two second pause and then continually repeats.
Page 11: Co & Smoke Alarm Silence Feature
Some individuals are more sensitive to CO than others, including people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers or elderly people can be more quickly and severely affected by CO. Members of sensitive populations should consult their doctors for advice on taking additional precautions.
