SMOKE ALARM FEATURES

• Model ADC features a False Alarm Control which, when activated, quiets unwanted alarms for up to 15 minutes.
• This smoke alarm is powered by 120V AC and a 9-volt battery back-up source. AC/DC smoke alarms offer added protection in the event of a power failure or a drained battery.
• Unique power connector prevents interconnection with incompatible smoke alarms or security systems.
• This smoke alarm may be interconnected with as many as 11 other Firex model FADC, AD and ADC smoke alarms, or as many as 6 Firex model ADH heat alarms for a total of not more than 18 interconnected devices.
• Optional tamper-resist feature can serve as a safeguard against tampering. • Unique “battery missing” lockout. The smoke alarm will not attach to the mounting bracket if a battery is not in the battery pocket.
• Improperly connected or weak battery signal. The smoke alarm will sound a short beep about once a minute if the battery is weak or improperly connected.
• Separate green and red LEDs indicate that the smoke alarm is receiving AC power, working under normal operation, in alarm, or under false alarm control.
• Loud alarm horn—85 decibels at 10 feet—sounds to alert you to an emergency.
• This alarm incorporates the internationally recognized horn signal for evacuation. During alarm mode, the horn produces three short beeps followed by a 2 second pause and then repeats. This pattern is somewhat different than the previous alarm sound, which continually beeped.
• Test button checks smoke alarm operation. Model ADC also features a False Alarm Control which, when activated, quiets unwanted alarms for up to 15 minutes.

Easy to install and reliable
Bought these to replace smoke detectors original to the house built in 1986 which should have been replaced a long time ago. I was religious in replacing them every 10 years in previous houses but I was lazy and put this off. We had a small kitchen fire which filled the whole house with smoke so thick you couldn’t see through it and not one went off which was a scary wake up call (luckily we have fire extinguishers and I was home when my wife screamed). I replaced 3 detectors with these and yes they did require a bit of electrical knowledge but it is minimal. Cut the power, remove wire harness, replace harness with wire nuts, put a couple screws in and done. Start to finish all 3 were done in maybe 30 mins. Longest time was moving the ladder. These look good and we are much safer. Wife burned dinner a couple weeks later with a little bit of smoke and they went off (don’t ask). Bottom line, I tested my old units regularly by hitting the test button and they all sounded. When there was a fire emergency they all failed. I’d invest a few bucks any day to protect my family. To top it off they came with batteries! I wish there would not be a test button on any detector but rather require a real smoke test to ensure performance.
