1. What type of alarm should I buy?

When choosing a smoke alarm, there are several things to consider. Dozens of reputable brands of smoke detectors are readily available. No matter where you buy your detectors, be sure to buy only "listed" units. The Underwriters Laboratories (UL) or Factory Mutual (FM) mark on your smoke detector will ensure that it was evaluated and it meets nationally recognized safety requirements.

2. How many should I have?

It is important for every household to have at least one smoke detector; however, more is optimal. The quicker the smoke detector senses the smoke, the quicker you will know about it and the more time you and your family will have to act appropriately or evacuate to safety. The Poway Fire Department recommends that every home have a smoke detector in each hallway leading to bedrooms, in each bedroom itself, and on every level of the home. The Uniform Building Code requires a smoke alarm inside each sleeping area for new construction. Smoke detectors can be powered by either battery or "hard-wired" into your home's electrical system with a battery back-up in case of a power failure. The best system is to have all of the smoke detectors in your home hard-wired with battery back up and inner-connected (when 1 smoke alarm goes off, all smoke alarms sound at once). Smoke alarms are not recommended for kitchens or garages.

3. Where should I place them?

The placement of smoke detectors is very important. Sleeping areas need the most protection. One alarm in a short hallway outside the bedroom area is usually adequate; however, longer hallways should have one at each end. For maximum protection, install an alarm in each bedroom.

4. How often should I change the battery in my smoke detector?

It is recommended that you change the batteries in your smoke detector twice a year. An easy way to remember is to change the batteries every spring and fall when you adjust your clocks for time change. "Change your clock, change your battery." If your smoke detector starts making a chirping sound, this is also an indicator that the battery needs to be replaced.

5. When do I need to replace my smoke detector?

Always follow the manufacturer’s instructions, but typically they should be replaced at around 10 years. Like any appliance, smoke alarms wear out and the likelihood of them failing increases after this time.

6. How and when should I test my smoke detector?

It is extremely important to test and clean all detectors regularly. Clean the alarm face and grill often to remove dust and lint. Never paint a smoke detector as it may interfere with proper function of the alarm. Check the smoke alarm monthly by pushing the test button. Be sure to replace the batteries at least once a year.
