I have three kidde nighthawk ci ombo smoke co alarms in my house.

Nighthawk fire alarm two beeps.

The battery is low and needs to be replaced or the alarm has malfunctioned. I read the back and it said to replace the read more. Make sure the battery is facing the right direction. An alarm will chirp every 30 to 40 seconds for approximately seven minutes while the hush feature is activated.

An alarm will chirp every 30 seconds to indicate it s time to replace the alarm. If the alarm portion is working properly the lcd will display 888 and then display a number around 200. Emergency procedure if co is detected. This sort of noise usually means one of the following.

To reset your fire alarm and stop the smoke detector from beeping. Mount them on a wall where the carbon monoxide alarm beeping will be heard loudly enough to wake up everyone nearby. Remove the detector from its mounting bracket and unplug the power supply. Turn off the power to the smoke detector at your circuit breaker.

It needs to be removed to activate the alarm. It s annoying but it s usually nothing to worry about. It will then display 888 again. Insert a fresh duracell energizer or everready battery.

Batteries are not facing the right direction. Press and hold the test reset button to test the alarm. About 1x per minute low battery most common. Check the alarm by pressing the test button monthly.

The nighthawk will then issue four quick beeps wait five seconds and then issue four more beeps. Do they get old and need to be replaced. The best way to deal with this is to press the reset button on the alarm and then replace the battery with a new one. Battery pull tab is still in the alarm.

Some may run on electricity no battery and when you detach from ceiling the power is removed. There may be interference from a similar system nearby wireless alarms only. Alarm has been beeping every 30 seconds. Battery drawer is open or partially open.
