1Description
The releasing module XCI2001 supports activation of releasing valves in releasing and
sprinkler systems. Activation can be event-controlled or performed manually. The
releasing module is mounted on the periphery board.
Properties
●Automatic or manual activation
●Dual-channel control
●Supervision of releasing circuit (wiring as class A or class B circuit)
●Supports several valve systems
●Suited to indoor applications (not wet rooms)
