Minimaster RCMM

RCMM is an enclosed microprocessor based, intelligent, self-monitoring control panel.

Quick facts

  • RCMM is used as a simplified main central unit with control units RCBK, RCMU or RCDU2 as subcentres that can be connected in a network for shared functionality.

Function

RCMM is an enclosed microprocessor based, intelligent, self-monitoring control panel. It is used as a simplified main central unit with control units RCBK or RCMU as sub-centres that can be connected in a network for shared functionality for alarm operation, external alarm, night operation, function test and resetting.

The communication between RCMM and the connected RCBK / RCMU takes place via a two wire potential free BUS cable with free structure (free topology) in a linear, ringshaped or star-shaped network. When the RCBK/RCMU control units are connected, they switch from working as independent units to being controlled centrally from the network’s minimaster RCMM.

RCMM performs automatic function checks every 48 hours after going live/resetting/activated input Function test. For communication faults, the RCBK or RCMU sub-centres assume alarm operation. The operational status of RCBK or RCMU is indicated as per the previous description of each panel while an indication that a sub-centre has assumed alarm operation is made in minimaster RCMM. All acknowledgement/ resetting of alarms is done on the RCMM after the fault has been remedied and not on the sub-centre that has given the alarm.
