The Hochiki FireNET Vapor VPR-SD1 is an aspirating smoke detection system that utilizes an air-sampling pipe network to draw air toward an analog detector installed inside a sealed enclosure.  The pre-engineered VPR-SD1 system has one pipe inlet and provision for one or two analog addressable smoke sensors, allowing redundant or double-knock detection.  The VPR-SD1 is configurable for a variety of environments, providing an ideal fire detection solution for correctional facilities, transformer vaults, elevator machine rooms, HVAC ducts, and others.
