How to test an industrial smoke detector

1. Using the test button:

Locate the test button on your smoke detector (usually in the center or on the side).

Press and hold the button for a few seconds until the alarm sounds.

This verifies the detector's circuitry, batteries, and alarm sound.

However, this test does not confirm the sensor's ability to detect smoke.

2. Professional aerosol testers:

These testers, available at hardware stores, simulate smoke by releasing a controlled aerosol spray into the detector.

Point the tester at the detector from a distance (e.g., 2 feet) and activate it.

The detector should activate, confirming its ability to sense smoke.

3. Calibrated test methods:

These methods use specialized equipment to introduce a controlled amount of smoke (or simulated smoke) into the detector.

For example, the TruTest device connects directly to the detector and pumps smoke at a measured rate to check sensitivity.

This is often used for older detectors or when a more precise sensitivity test is needed.

4. Comprehensive Testing:

For a thorough inspection, you may want to consider multiple methods.

Check the detector for dust or debris that could affect its performance and clean it if necessary.

Check the detector's connection to the fire alarm control panel.

If the detector is part of a larger system, make sure all connected detectors sound an alarm when one is activated.

Record all test results and any corrective actions taken.

5. Professional Testing:

For industrial-grade detectors and systems, consider a professional fire safety technician who is trained in specialized testing methods.

They can ensure your detectors are properly calibrated and operating at peak performance.

They can also identify potential problems and recommend appropriate solutions.
