Smoke/Carbon Monoxide Detectors
It is a proven fact that smoke detectors and carbon monoxide detectors save lives! For the safety and well-being of your family - use them. Change your batteries twice a year: when you turn your clocks forward in the spring and when you turn your clocks back in the fall. If your alarms "chirp" at you once in a while they are telling you to change the batteries or replace the entire unit. If the unit is older than ten (10) years replace it. Help them to save your life by keeping them clean and free of dust and debris.
