Smoke Detector
The 800 Series MX VIRTUAL detectors include a host of installation and service features which are provided to reduce installation and service costs and reduce repair times.
All 800 Series detectors communicate to the MX detection panel using the fast reliable MX DIGITAL loop protocol. This allows each detector to operate in one or two of several detection modes, thus allowing it to be easily optimised to the risk.
To meet detection applications with multiple risks the 811PH and 811CH detectors allow two detection modes to operate simultaneously.
The use of virtual detection means that installations can change the detection mode without any physical change, taking place. Not only can the detection be changed at the time of installation and commissioning but also during the life of the vessel as vessel usage changes.
Some MX detection panels even allow the detection mode to be changed at different times of the day or automatically as occupancy and activity in the space changes.
As well as providing great flexibility, using only two detector models means whole life costs are reduced by reducing manufacturing, stocking and service stocks. This also reduces the number of times detectors have to be changed during the life of the installation.
Heat Detector

The 811H is a flexible cost-effective addressable heat detector with all the features of MX VIRTUAL detectors. The 811H returns the temperature to the MX detection panel which allows various detection panel which allows various detection modes to be implemented. The 811H uses a high quality thermistor with very low Thermal mass. This allows the detectors to provide fast accurate temperature detection as well as heat detection.
Flame Detector

The 811F and 811FEx point type flame detectors are part of the MXTechnology® range of digital addressable fire detectors. MXTechnology incorporates heat, optical and carbon monoxide detection. The 811F and 811FEx flame detectors present a cost effective solution to providing false alarm free flame detection for enclosed applications.
Both the 811F and the 811FEx are full featured solar blind flame detectors for enclosed use and boast a high degree of false alarm immunity. The standard unit is the 811F and it is designed for direct connection to the MX digital loop, employing the same detector base or functional base as other 800 series fire detectors.
The 811FEx is an intrinsically safe version intended for use in hazardous atmospheres and must be connected via an EXI800 interface and galvanic isolator. The detectors are designed to comply with EN 50 014 and EN50 020 for intrinsically safe apparatus. They are certified: ATEX code: II 1 G Cenelec code: EEx ia IIC T4.
