MR601TEX High Performance Optical Intrinsically Safe

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

The MR601TEX has been developed to overcome the slower response of the optical detectors to hot burning fires, by increasing the sensitivity of the optical detector when it is associated with a rapid change in temperature. In this way it is intended to become a detector which can cover some of the risks currently covered by ion chamber detectors. Smoke detectors will not detect burning alcohol or other clean-burning liquids which do not generate smoke particles.

MD611EX Fixed Temperature Heat Detector

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

Where environmental conditions rule out the use of smoke detectors, MD601Ex/MD611Ex heat detectors may provide an acceptable, though less sensitive, alternative. For general use (particularly where the ambient temperature may be low) a ‘Rate-of-Rise’ (ROR) heat sensor is preferred. These detectors react to abnormally high rates of change of temperature and provide the fastest response over a wide range of ambient temperatures. A fixed temperature limit is incorporated in these detectors. In kitchens and boiler rooms etc, sudden, large changes in temperature are considered ‘normal’. Fixed temp. [static] detectors should be used in this case.

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

– Dimensions 109 dia x 43 H mm
– Weight 126g
– ATEX Certificate BAS01ATEX1134X
– IECEX Certificate BAS 07.0056X
