Gas Detector Control Panel

Single Channel - Wall Mount

Type MCU1 - For use with an integral or remote fixed gas detector head.

Single Channel Gas Monitoring Control Unit Type MCU1 - Status Scientific Controls


  • Integral sensor options comprise CO2 (Infrared), oxygen, or a wide range of toxic sensors.
  • Can be used with the full range of Status Scientific Controls fixed gas detector heads - certified types require use of an integral safety barrier.
  • Green, amber and red flashing indicators in lens section.
  • Alphanumeric display with backlight.
  • Full calibration menu via external push buttons.
  • Integral audible alarm.
  • Internal sealed lead-acid standby battery option.
  • Internal safety barrier option.
  • Lockable door.
  • Water and dust proof to IP66.
  • Compatible with industry standard gas detectors and other sensors.


The MCU1 is a single channel, wall mounting, monitoring and control unit for use in a safe area where there is no risk of the presence of potentially explosive gases. It can be used in either of the following ways:-

1. Fitted with an integral CO2 (Infrared), oxygen, or toxic sensor for safe area use only.

2. Connected to a remote CO2 (Infrared), oxygen, or a toxic gas detector head for safe area use only.

3. Fitted with an internal (or external) safety barrier and connected to a remote certified intrinsically safe (Ex ia) flammable, oxygen or toxic gas detector head sited in a hazardous area. (The range of heads includes flammable and CO2 (Infrared) types).

4. Connected to a remote flameproof (Ex d) certified flammable, oxygen or toxic gas detector head sited in a hazardous area. (The range of heads includes flammable and CO2 (Infrared) types). In this case a safety barrier is not necessary.

Internal Safety Barrier

Internal Safety Barrier

For applications where the gas detector head (or other sensor type) is sited in a potentially explosive atmosphere, a safety barrier must be fitted in order to limit the maximum voltage and current under a fault condition (e.g. short circuit) such that an incendive spark cannot be created. Where suitable*, the internal safety barrier shown above may be fitted within the control unit. This can either be fitted at the time of manufacture (where requested) or at a later time if the system is extended by the installation of additional detectors.

*Note that some installations may neccessitate the use of external barriers sited at the safe area/hazardous area interface - see the accessories page.
