The Orbis Heat Detector monitors temperature by using a single thermistor which provides a voltage output proportional to the external air temperature.

• Can be used for applications where smoke detectors are unsuitable
• Ideal in environments that are dirty or smoky under normal conditions
• Red flashing LED at StartUp confirms the device is operating.
• SensAlert®, yellow flashing LED indicates faulty operation
• FasTest® takes just four seconds to test and confirm detectors are functioning correctly

The Orbis Marine Optical Smoke Detector operates on the well-established light scatter principle. However, the sensing technology is radically different in design from previous optical detectors and significantly reduces false alarms.

• Responds well to fast-burning, flaming fires
• Reduced false alarms
• Increased reliability of detection
• Sensing chamber keeps out dust and other airborne contaminants
• Operates over a broad range of voltages at extremes of temperature
• Flashing LED option
