2.10 Signal Concentrator
In the XMP1 system, the signal concentrator module
(62.7040.180.00-A001, AN00275454) provides interfaces (sensors and
transmitters) to external units. This new module is generally referred to as
"SIG II signal concentrator". It substitutes the signal concentrator module
(62.7006.180.00-A001).
Using the sensors, messages received from external devices can be
processed. In addition, such external devices can be controlled via the
transmitters.
Possible signal sources:
• Alarm signals from external units with 7R signalling
• A-/B-/EL alarms
• ZA(A)/ZA(B) contacts
• Door contacts
• Fire detectors
The following devices can be controlled via the transmitters:
• Central alarm signalling unit
• Switching circuits triggered by alarms and messages
Extended alarm signalling
The signal concentrator can also be used for additional alarm signalling for
XMP1 modules via signalling outputs. In this case, the module is displayed
by the Operator Terminal under "EA ext. alarm signalling" modules. The
signal concentrator can be assigned to another module and indicates the
alarm status of the latter via relay contacts (transmitters).
