Intrinsically Safe Detectors

MR601TEx Intrinsically Safe High Performance Optical Smoke Detector

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.

MU601Ex Intrinsically Safe Point Type Carbon Monoxide Detector

The CO Fire detector is a unique general purpose fire detector which provides very early warning of slow smouldering fires. Ideal for sleeping risks, the CO fire detector is also well suited to many applications where heat detection is insufficient but smoke detection causes false 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.

Specifications

  • Operating Voltage: 18 to 32Vdc
  • Operating Current: 70 μA (max.)
  • Alarm Current: 33 to 72mA
  • Operating Temp: 0°C to +50°C
  • Relative Humidity: 90% (non-cond.)
  • ATEX Certificate: BAS01ATEX1134X
  • ATEX Code: Ex II 1 G
  • Cenelec Code: EEx ia IIC T5

MD601Ex/MD611Ex Intrinsically Safe Heat Detectors

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.

Specifications

  • Operating Voltage: 18 to 32Vdc
  • Operating Current: 100μA (max.)
  • Alarm Current: 5 to 80mA
  • Operating Temp: -20°C to +70°C
  • Relative Humidity: 95% (non-cond.)

T54B Probe Type Heat Detector

Constructed from stainless steel, the T54B is an extremely rugged heat detector that can be used to detect fires in the harshest of environments. The T54B can be used in environments with ambient temperatures up to 280°C and, being hermetically sealed, is impervious to most contaminants. The T54B is a simple device and therefore suitable for use in intrinsically safe areas when used with a suitable I.S. barrier. For reliable operation, it is recommended that T54B detectors have set points 20°C or 20% (whichever is higher) above the maximum temperature they will be exposed to in normal operation. Preferred factory preset temperatures range from 60° to 250°C; with normally open contacts. Other temperatures and normally closed contacts are available by request.
