Features

Helios duct smoke detector KRM with DIBt approval for early smoke detection in ventilation ducts. It combines a smoke detector with an adapter system whose measuring tube and housing have been adapted for an optimised air flow through the smoke detector. Can be mounted on ventilation ducts with either round or rectangular cross-sections. A mounting bracket (KRM-MK) is required for mounting on round or insulated ducts. The protective casing (KRM-G) is required for outdoor installation or installation in cold environments. The degree of contamination is signalled on a two-line LED display. Due to the alarm threshold adjustment, the sensitivity remains the same until total contamination occurs. To ensure functionality, the duct smoke detector has an electronic air flow monitoring system. The delivery includes a 600 mm air duct sample tube, which can be shortened if necessary.
