835/855 Addressable Detectors
A Failsafe System You Can Rely On
The 835/855 range of detectors use the Zettler digital protocol to provide robust and reliable communications to the control panel. A wide range of cable types can be used and the open topology capability of the system makes it ideal for the upgrade of older systems whilst reusing the cables to reduce cost.
- With the ability to detect a wide range of fires from flaming to smoldering types, the combined optical and heat multi-sensor detector is the preferred choice for multiple environments including, light industrial, retail, and offices.
Suited For A Variety of Environments
The Generation 6 855 multi sensors have six detection modes and employs three detection channels: heat, smoke, and combustion gas (carbon monoxide). These channels are combined in software designed to provide optimum detection based on the occupancy and risk. For either or both of these changes, the detection mode can be changed in suit. Both the 835 / 855 PC provide the best technology in detector performance and false alarm detection. These multi-sensors that monitor smoke, heat, and CO levels help to accurately determine the presence of fire. These sensors are particularly useful when the environmental conditions are challenging – for example, within the industrial, retail, transport hubs and healthcare sectors.
