Smoke Alarm Tester Spray Can
This can of 2.5 ounce aerosol spray can be used as a non-toxic, environmentally friendly way to test smoke detectors—both ionization and photoelectric.
Testing your smoke detection device is as simple as spraying the contents of this can near the alarm. If the alarm sounds, you should be okay. If not, it’s time to do some maintenance on your fire alarm system.
