Testifire 9001-001 9MTR Smoke/Heat Kit Testifire 9000 Series is the world’s first multi-stimulus detector tester for smoke, heat detectors Testing kit. Both smoke and heat stimuli are created in a single test unit, and delivered individually, or – for the first time – simultaneously; in whichever combination are required. Testifire does this without using pressurised cans of gas or other hazardous goods. Stimuli (Smoke and Heat) are generated at the time of test using safe and patented processes fuelled by replaceable capsules.
