Free battery operated smoke detectors (not hard wired) are available for residents living within the San Marcos City limits. If you need help installing or checking the batteries in your home smoke detectors, SMFD can install new battery operated smoke detectors and assist with battery issues. Please fill out the request below and we'll get in contact with you.
Newly built homes (0-10 years old) often have hard-wired smoke detectors systems installed. If you have one of these systems, they may require more than just the recommended 6 month backup battery replacement. The smoke detector itself, and not its battery, may require replacement. Please read your manual to call an electrician or contact your alarm company if needed.
**At least 3 days advanced notice required**
