Using a Smoke Detector Tester

Using a smoke detector tester is another method to check that your system is working effectively. Smoke detector testers are commercially available and can help you check the effectiveness of your detectors smoke sensors but not the battery or electrical current.

Smoke in Aerosol Cans

Smoke testers are typically aerosol cans that emit simulated particles that can mimic the smoke produced by a fire. There are several manufacturers that produce this product and you can search online for a distributor.

Effective Tests

Since aerosol sprays test the ability of the alarm to sense the presence of smoke, they can effectively test either photoelectric or ionization fire alarms by simply spraying a burst from the aerosol can near the detector to determine whether the alarm responds to the simulated smoke. The independent testing authority, Underwriters Labs, tests aerosol products. These third-party reference tests are rigorous examinations of the product. Most major smoke detector manufacturers not only seek to have detectors rated, but want their products tested by quality testers as well. Make sure the smoke detector tester you select is approved by the UL.

Typical Product

A typical smoke tester is usually packaged as a 2.5-ounce spray can that has a capacity for 200 sprays.  It can be purchased for approximately $15. Testers also have available accessories such as extension tubes approximately 18 inches long that can direct the spray from a distance. Use of a tube can improve the accuracy of your test. Pole extension holders are also available for testing mechanisms located on high ceilings. To use the pole extension, place the can at the top of the broom-handle-like pole that has a trigger mechanism at the bottom.

Simple to Use

Instead of lighting candles or other incendiary devices, use of an aerosol spray smoke detector tester can provide the user with a safe method to verify the smoke detectors effectiveness. Simply hold the can at a distance of two to four feet, aim and spray for one to two seconds at the vents on the sides of the smoke detector. An alarm should sound within one to 10 seconds if your smoke detector is operating effectively. If the detector has a delay circuitry, spray one or two additional times to make sure the device is operating properly.

Pole Operation Available

For smoke detectors that are located in high places that are not normally accessible without use of a ladder, a pole extension accessory is typically available. Use of this accessory eliminates the need for a ladder and does not put the person testing the device in an unsafe situation. A pole accessory allows the user to place the aerosol can at one end of the pole while operating the can from a trigger at the other end of the pole. Many manufacturers sell pole extension accessories as part of a kit that includes the aerosol spray tester and a carrying bag.

Smoke tester kits are sometimes packaged with compressed air to clean out detectors after testing.
