*Aerosol smoke can be purchased from Home Safeguard Industries at home-
safeguard.com, model 25S Smoke Detector Tester, and Chekkit Smoke De-
tector Tester model CHEK02 and CHEK06 available from SDi. When used
properly, the canned smoke agent will cause the smoke detector to go into
alarm. Refer to the manufacturer’s published instructions for proper use of the
canned smoke agent.
CAUTION
Canned aerosol simulated smoke (canned smoke agent) formulas will vary by
manufacturer. Misuse or overuse to these products may have long term ad-
verse effects on the smoke detector. Consult the canned smoke agent manufac-
turer’s published instructions for any further warnings or caution statements.
