Description | Specifications/Features | FAQ | Related Products | Uses | Blog | Manual


Smoke Check™ smoke detector tester is used to safely test the proper functioning of smoke detectors and smoke alarms. With no dangerous flames or fumes, Smoke Check™ smoke in a can tests both photoelectric and ionization type smoke detectors to ensure circuitry and alarm systems are in proper working order and actively sampling the air for any hint of a fire.

Please Note: Pressing the "test button" on a smoke detector tests battery strength only. The test button cannot be used to verify the smoke detector's ability to activate its alarm in the presence of smoke caused by a fire. Smoke Check™ Smoke Detector Tester was designed specifically to verify the smoke detector's proper functioning.
