830/850 Series Generation 6 Detectors & Accessories

The all new 850 & 830 series of detectors and detector accessories offer superior levels of performance and many features designed to cut the cost of installation and service.


  • Improved Detection Performance
  • Greater Fault Tolerance
  • Better Environmental Protection
  • Easier and Quicker to Install
  • Lower Lifetime Cost

The 850 and 830 series fire detectors are designed to be both adaptable and flexible which means they can be used in most premises to protect against a wide range of potential fire risks. They use sophisticated digital signalling to communicate with the MZX Technology fire control panel. Using the 850EMT Engineering Management Tool, which communicates with the detector via a two way infrared link together with a range of bases and accessories, they are quick and easy to install.

Colour options allow the detectors to either blend into the decor or be easily spotted against a contrasting background. System designers can choose between a built-in line isolator with the 850 series.

The detector bases are designed to snap-fit to the ceiling tile adaptor or can be screw fixed to a ceiling or electrical box in the traditional manner. A park position allows the detector to be mechanically attached to the base without making electrical connection to facilitate the testing of electronic free bases. 

The 850EMT is a commissioning tool that communicates with 850 series fire devices via a two way infrared link. It is designed to speed up and simplify installation and commissioning, reduce the possibility of engineering error and improve health and safety by removing the need for working at height.

850PH and 830PH Photo Heat Detector
With the ability to detect a wide range of fires from flaming to smouldering types, the combined optical and heat multi-sensor detector is the preferred choice for a range of applications including light industrial, retail and office environments. It operates in a number of approved modes and sensitivities that can be dynamically selected to suit different environmental conditions.

850P and 830P Photo Detector
More benign environments where any potential fire will be slow burning can be protected using the optical detector. A choice of sensitivities and modes gives this detector a broad range of applications.

850H and 830H Heat Detector
To compliment the range the heat sensor can operate in fixed temperature and rate-of-rise modes with a number of approved sensitivities. Most often used in areas where high levels of dust are present or where the environment precludes the use of smoke detectors.

850PC and 830PC 3oTec Triple Sensor Detector
For life protection and when the environmental conditions are challenging, the 3oTec detector provides the ultimate in detector performance and false alarm rejection. It is a multi sensor that monitors smoke, heat and CO levels in concert to accurately determine the presence of fire. Applications include industrial, retail, transport hubs, and healthcare. Its false alarm rejection properties make it the ideal choice for hotel bedrooms where steam from bathrooms is a common source of false alarms.
Remote Detector Indicators
A range of remote detector indicators including the 801RIL and 801HL units.
A wide range of accessories are available including the 850 EMT Engineering Management Tool.
Colour Options
Detectors are supplied white as standard. A range of colours are available, these are supplied as packs of ten detector covers and continuity bases. A sample pack is also available that contains one cover and one base in each of the standard 10 colours. In addition to the 10 stocked shades, any Pantone colour can be supplied as a special order for quantities of 100 or over.
