- for monitoring ventilation ducts in connection with a fire alarm system or the building management system
- for the control of ventilators
- with alarm and fault storage in case of power failure
- DIBt approval Z-78.6-250
- VdS recognition G 221008
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. 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
The advantages of the pro-Version:
- LCD display with comfortable operation
- galvanically isolated RS485 interface with BACnet MS/TP or Modbus RTU protocol
- integrated flow monitoring
- visualization of the contamination level via LED
