Spray
aerosol smoke* through the test hole. Wait approximately 20 seconds for the detector to alarm. If the air speed in
the duct is high, it may be required to repeat the test due to high dilution of the aerosol smoke.
NOTE:
Verify that the Test Hole Plug is replaced after the test.
Consult
Table 8.1
(Alarm status) for more details.
* Aerosol smoke can be purchased from Home Safeguard Industries at homesafeguard.com, model HO-25S
