DCM1 & DCM1e Installation and User Guide V1.062

Section 5: Appendix

Larger systems – cascading DCM1s

If an installation requires more than eight Zones, multiple

DCM1s may be interconnected to provide a system with

a larger number of outputs. For example, two DCM1s will

provide 16 zones, three DCM1s 24 zones, and so on.

System Interconnections

In order to provide a transparent system which can be

operated with the same ease as one with a single DCM1,

interconnections between multiple DCM1s must follow a

few rules. The range of possibilities afforded by using multiple

DCM1s is extremely large, and each installation will be guided

by the user’s requirements and the building layout.

The example given is for a simple 16-zone system comprising

2 DCM1s, with a CDR-1 in each of the 16 zones. The block

diagram below shows how the various inputs are – or are

not – interconnected. All possible connections have been

depicted, though it is recognised that most systems will not

use all of a DCM1’s connectivity simultaneously.
