Light the igniter : (please refer to the diagram)

Take out the head cover.(cover is for protection purpose)

Filled up with gas (same as lighter's gas) from the bottom of igniter.

Move the gas switch to “ON” position.

Turn on the lighter at “A” zone until red light appears at “B” zone. (blow out the flame if appears, this could extend the life of igniter and prevent the damage to detector)

Place the lighted igniter into bracket of test vessel.

Adjust the vessel until the tested detector is totally covered.

When the confirmation LED lights up during test, user can take away the test device. (test period for rate of rise detector is about 5 seconds, fixed temperature detector is about 10 seconds)

Take the bracket out

Place the smoke tester into test vessel, then adjust the vessel until the selected detector is totally covered.

Push test device up 1-2 times (about 1sec per time) to allow the smoke tester sprays out particles and into the smoke detector's chamber (aerosol is composed of particle sizes comparable to those generated in the early stage of a fire) To avoid the particles be blew away by wind, please do not move the vessel and wait about 10 seconds for activation.

If the test device is not used, use smoke tester from a distance of 0.1 to 1.0m aim spray for 1-2 second at the vents of the detector. Alarm will sound within 1-20 seconds if the detector functions properly unless the detector has a built-in delay circuit. Detectors with delay circuits should be sprayed 1 or 2 additional times to activate the alarm.
