The CCR provides the Alarm/Trouble/Supervisory Relays and The MLR provides for Masterbox or Line Reversal connections
Common Control Relays
Distributed Architecture
All FC-250 modules operate independently. There is no central operating system, no central point of failure. Processing power is distributed throughout the campus, increasing system survivability, eliminating home-run wiring costs while decreasing downtime due to system maintenance.
Highly Survivable
Since NAC’s and SLC’s are grouped on the same module and events are processed locally, ALM modules will perform local operations even if network communication has been severed. Distributed modules also minimize campus-wide downtime by restricting maintenance to the local module.
The CCR3 provides for Common Alarm, Common Trouble and Common Supervisory relays (NO/CO/NC) activated by events anywhere on the fire control network. The three relays are rated at 2.0A @30 VDC Resistive load each.
The CCR3 can be mounted with any VPM or SDM installed on the network fire system by a simple ribbon cable connection. Multiple instances of the CCR3 may be installed as required on each display module installed on the network and up to two CCR3 boards may be daisy chained together off of any single network module. The CCR3 is mounted directly to the system chassis within the cabinet.
The MLR3 is also mounted with any display module installed on the network fire system by a simple ribbon cable connection. If present, the MLR3 may be daisy-chained directly off of the CCR3. The MLR3 is mounted directly to the system chassis within the cabinet.
