OR4 smoke detector
OR4 basic and OR4 pro smoke detectors detect smoke in ventilation ducts. They control fire protection and smoke protection dampers and can trigger them. Alarm and fault messages are stored in the event of a power failure. The short distance required to fault locations offers flexibility in application. The smoke detectors have DIBt approval and VdS recognition.

Product details
The OR4 basic and OR4 pro smoke detectors detect smoke in ventilation ducts. In the event of a fire, they are used to control and trigger fire dampers and smoke protection dampers. In addition, fans can be controlled. When integrated into a building management system or fire alarm system, they can forward important control signals to these systems.
Implementation of control scenarios
Early detection of smoke in the ventilation duct allows necessary and planned control scenarios to be activated to prevent smoke from spreading to other fire compartments. The DIBt approval Z-78.6-250 confirms the conformity of the smoke detector for controlling and triggering a generally approved shut-off device against the spread of fire and smoke in air ducts.
The OR4 basic smoke detector and the OR4 pro, which is equipped with additional convenient features, offer you many advantages.
Advantages of the OR4 basic smoke detector
- Alarm and fault memory in the event of a power failure
- Position and air direction-independent installation
- Time-saving, tool-free access to the smoke switch for quick function testing
- Low installation distance 1.5x hydraulic diameter to fault locations (in front, behind)
- Evaluation electronics encapsulated and protected against contamination by design
- Universal power supply for 230V AC or 24V AC/DC with automatic detection
- Cable glands with strain relief for up to seven connecting ducts
- TEST/RESET directly on the device and externally via the GLT interface input
- Protective screen to protect the smoke switch from coarse soiling and to extend its service life
- DIBt approval Z-78.6-250
- VdS approval G221008
Additional advantages of the OR4 smoke detector
- LCD display simplifies diagnosis, display, and setting of operating parameters
- Galvanically isolated RS485 interface with BACnet MS/TP or Modbus RTU protocol
- Integrated flow monitoring via flow sensor
- Visualization of the degree of contamination via LED
Note: For both product variants, replacement of the smoke switch is recommended after 8 years of operation.
