This is a long range beam type smoke detector that consists of a 50042 master unit and a 50041 slave receiver unit. This was just removed from a working fire alarm system for an upgrade. This unit has worked fine and never caused any false alarms.
The SuperDuct two-wire duct smoke detector is ideally suited to applications where early indication of combustion is required within the confined space of ventilation ductwork. Its primary purpose is to provide early warning of an impending fire and to prevent smoke from circulating throughout the building. It is typically used to detect smoke in the supply side of the HVAC system but can provide supervision of the return side as well.
