MRM

ISA SEQUENCE ALARM MODULE WITH SEPARATE LIGHT SIGNALLING 

The MRM alarm module and the MTLM horn and flashing module, made of a self-extinguishing polyamide container, are suitable for mounting indifferently on both EN50022 (OMEGA) and EN50035 (DIN 1) profiles. In addition, being able to manage each individual module, 2 alarm points, the MRM module is particularly suitable for use where the dimensions available for housing the alarms are extremely small.

  • Installation flexibility
  • 90° pull-out terminals
