MX 801CHEx Intrinsically Safe (I.S) Carbon Monoxide & Heat Detector

AJBPIKE — Sun, 07 Oct 2018 13:29:54 +0000

The 801CHEx Intrinsically Safe Carbon Monoxide plus Heat Detector forms part of the 800Ex Intrinsically Safe Series of MX Addressable Fire Detectors. The detector plugs into a 5BEx base. The detector is designed to transmit to a remote MX fire controller, digital signals which represent the status of the carbon monoxide and heat elements of the detector. Software within the controller is used to interpret the returned Carbon Monoxide and heat values to raise an alarm or other appropriate response according to the programmed configuration.

The mode of detector may be:
– Heat only detector (A1R or A2S) (sensitivity: High, Normal or Low)
– Compensated Carbon Monoxide detector (sensitivity: High, Normal or Low)
– Compensated Carbon Monoxide detector (sensitivity: High or Normal ) combined with heat (A1R)

These detectors are designed to comply with EN 50 014 and EN 50 020 for intrinsically safe apparatus.

They are certified:
– ATEX Code: Ex II 1G
– IECEX Code: Ex ia IIC T5
– Cenelec Code: EEx ia IIC T5

Specifications
– Operating Voltage 18 to 24Vdc
– Queiscent Current 400µA (max.)
– Alarm Current 3.5mA (max.)
– Operating Tempearture 0°C to +50°C
– Relative Humidity 15% to 90% (non-cond.)
– FPANZ Listed VF/352
– IECEX Certificate IECEX BAS 07.0063X

TYCO 614CH Conventional Carbon Monoxide Detector

AJBPIKE — Sun, 07 Oct 2018 13:28:29 +0000

The 614CH fire detector provides very early warning of slow smouldering fires. The CO fire detector is well suited to many applications where heat detection is insufficient but smoke detection causes unwanted alarms. As CO travels more freely than smoke, the positioning of CO fire detectors is more flexible.

This feature is particularly useful in large complex structures such as atria and warehouses, where positioning of smoke detectors is difficult. The 614CH has an additional mode of operation as a Class A1R combined rate-of-rise and 60°C fixed temperature heat detector to supplement the CO detector mode to permit the detector to react to a wider range of fire types.

Although the 614CH has a rated service life of 10 years, in orderc for the 614CH to provide the intended level of fire detection, the detector should be checked for calibration 5 years after installation (or 5 years after re-installation following service) or within 7 years of the date of manufacture.

Specifications
– Operating Voltage 10 to 33Vdc
– Quiescent Current 55µA (max.)
– Alarm Current 3.2 to 67mA (50°C)*
– Alarm State Voltage 2.5 to 7.4Vdc
– Alarm Threshold 38ppm CO
– Ext. Powered Load (max.) 50mA, 28Vdc
– Remote Indicator E500 Mk2 Series
– Relative Humidity 15 to 90% (n/cond)
– Ambient Temp 0 to +50°C
– Dimensions (incl. base) 127 dia x 54H (mm)
– Weight 200g with base
– FPANZ Listed VF/345

MDU601EX Enhanced Heat and Carbon Monoxide Detector

AJBPIKE — Sun, 07 Oct 2018 13:28:29 +0000

The MDU601EX detector combines the features of both the MU601EX detector and the MD601EX detector to provide a combined CO and Rate of Rise Heat Detector where the sensitivity of the CO detector is enhanced in response to a fast rate of change of temperature.

Specifications
– Operating Voltage 16 to 28Vdc
– Operating Current 70 µA (max.)
– Alarm Current 30mA @ 15Vdc
– Operating Temp -20°C to +70°C
– Relative Humidity 90% (non-cond.)
– Dimensions 109 dia x 43 H mm
– Weight 126g
– ATEX Certificate BAS01ATEX1134X
– IECEX Certificate BAS 07.0056X

814CH MX Carbon Monoxide/Heat Detector c/w coating Thermistor (UK)

AJBPIKE — Sun, 07 Oct 2018 13:28:29 +0000

The 814CH is a state-of-the-art combined CO and heat detector that allows a full set of detection modes to be implemented in the MX fire alarm panels to suit most fire detection applications. The 814CH is particularly well suited to areas and applications where smoke detector positioning is difficult or where smoke detectors are prone to false alarm. The 814CH uses a reliable electrochemical cell for the detection of CO. The integrated heat sensor monitors rate-of-rise and fixed temperature and has been tested as a stand alone heat detector.

The 814CH can operate in a wide variety of applications where combined risks mean that heat or CO detection alone would be insufficient. The 814CH has all the features of MX VIRTUAL detectors including self verification, temperature and CO level indication and superior service functions.

Specifications
– Operating Voltage 20 to 40Vdc
– Quiescent Current 275µA (typ.)
– Alarm Current 10mA with LED on
– Remote Indicator Tyco E500 Mk2
– Relative Humidity 15% to 90% (n/cond)
– Ambient Temperature 0°C to +50°C*
– Dimensions 109 dia x 43 h mm
– Weight 88g
– FPANZ Listed VF/337

* The 814CH may be operated between 0 and -20°C for short periods but with reduced performance
