Why Choose the O Range OSD

Reliable Detection

Photoelectric sensing technology with wide 9-33Vdc operating voltage ensures reliable smoke detection across varying installation conditions and power supply setups.

Complete Solution

Supplied complete with relay base for immediate installation. Up to 4 detectors per chain for comprehensive zone coverage from a single panel output.

Clear Indication

Pulsing LED in quiescent state confirms the detector is operational. Red alarm indicator provides immediate visual identification of smoke events.

Photoelectric Detection

Well-proven photoelectric sensing technology for reliable point-type smoke detection in fire detection and alarm systems.

Wide Operating Voltage

9-33Vdc operating range provides flexibility for different installation configurations and power supply setups.

Visual Alarm Indicator

Pulsing LED within the housing during quiescent state. External indicator LED turns red when in alarm for clear visual identification.

Relay Base Included

Complete with relay base for straightforward installation. OSD must be installed on a relay base to function as intended.

Max 4 Per Chain

Up to 4 detectors per chain connection, allowing multiple detection points across a zone from a single O Range panel output.

O Range Compatible

Designed for use with the O Range smoke control panel system for smoke detection when no building fire alarm is present.
