For over 40 years, HSI Fire & Safety has provided fire alarm test and maintenance professionals with a full line of equipment and accessories for functional smoke, carbon monoxide and heat detector testing.
Our products include SmokeCheck® and the patented PurCheck®.
Used by thousands of fire and safety professionals worldwide, our environmentally-friendly testing products meet compliance with US and global fire alarm codes and standards.
Under the latest EPA Significant New Alternatives Policy (SNAP) program -- specifically around EPA Rule 20, aerosol smoke detector testers that contain HFC-134a are now banned from 31st December 2017, so because PurCheck and SmokeCheck have always been made without HFCs or CFCs, both products remain fully compliant with the new regulations.
When lives and property are at stake, rely on detector testing products from HSI.
