The Orbis Marine Heat Detector uses a single thermistor to sense the temperature around the detector. We have 6 detectors available from the Orbis Marine range designed to suit a variety of operating conditions.

• Approved for use in marine environments
• Transient rejection for false alarm reduction
• Modern, low-profile design
• Responds well to fast-burning, flaming fires
• Good performance in both black and white smoke
• DirtAlert, warns service engineers via a flashing yellow LED that detectors need maintenance
• FasTest - a maintenance procedure that takes just four seconds to test detectors
• SensAlert - a yellow flashing LED indicates faulty operation
• High humidity tolerance at up to 90% RH
• Wider operating temperature -40°C to +70°C
