Product details

The OR4 basic and OR4 pro smoke detector can be used to monitor ventilation ducts to control fire dampers and fans and as part of the building control system or fire alarm system to detect smoke in ventilation ducts. Early detection of smoke in the ventilation duct allows necessary control scenarios to be activated to prevent smoke transmission to other fire compartments. In conjunction with a Wildeboer FR90 or FK90 fire damper with protective grille on both sides, the OR4 smoke release device can also be used for overflow openings (Ü-FK/Ü-FR). The cost-effective OR4 basic and the OR4 pro smoke detector equipped with further convenient features offer you the following advantages:

installation independent of position and direction of air flow
fast and tool-free access to the smoke switch for easy functional testing
installation with a small distance of only 1.5x hydraulic diameter to points of failure (in front and behind)
evaluation electronics encapsulated and constructively protected against contamination
universal power supply for 230V AC or 24V AC/DC with automatic recognition
cable glands with strain relief for up to seven connection lines
TEST/RESET directly at the device and externally via input of the BMS interface
protective screen to protect the smoke switch from coarse contamination
