Photoelectric smoke alarms respond better to slow smoldering fires caused by flammable liquids, paint, cleaning chemicals, etc. Learn More About Photoelectric Alarms

Dual sensing smoke alarms feature both ionization and photoelectric technologies that detect both fast-flaming fires and smoke from smoldering fires. Shop Dual Sensing Smoke Alarms

Since no one can cannot predict what type of fire will occur, the National Fire Prevention Association (NFPA) recommends installing both ionization and photoelectric alarms to maximize protection.

Fire Alarm Testing & Maintenance

NFPA - National Fire Protection Association

When working properly, smoke alarms help save lives. Performing regular testing and routine alarm maintenance also keeps you in compliance with state/local fire inspectors and your insurance carrier.

During your inspection:

  • Look for signs of tampering or disabling
  • Install fresh batteries
  • Ensure alarm is audible
  • Remove any obstructions that may affect performance

Fire alarm testing regulations and fire alarm maintenance vary by state. Always check with your local government for the most current testing requirements.

According to the National Fire Alarm Code (NFPA 72), pull station alarms should be tested annually. For a code-compliant test, you must make sure the pull handle mechanism operates properly and that the station initiates an alarm at the fire control unit.

When to Replace Fire Alarms

According to the National Fire Protection Association (NFPA), smoke alarms should be replaced according to the manufacturer's recommendations, or when they do not respond properly when tested.
