A change in the electrical current to the wired smoke alarm will cause the smoke alarm sound to go off when there is not smoke in the air. A loose wire in the smoke detector can also cause it to go off as the electrical current is cut off and then restored to the alarm. A faulty smoke detector can cause all the smoke to chirp as well. JMC Electric recommends replacing your batteries once a year. If your alarms are overdue for replacement, according to the National Fire Protection Association, which recommends that you replace a detector when it’s 10 years old. JMC Electric offers a 10-year battery, hard wired smoke/carbon detector. For pricing call JMC Electric anytime for a free onsite consultation with a written estimate with no obligations or costs.
