CirrusPro Engineer’s Manual
Displays can be set up to connect to a single Detector Node or to monitor all nodes and display
information from any detector.
Setting the Connect Node to 000 allows the display to monitor all the detectors.
Setting the Connect Node to any value 224 to 255 automatically connects the display to that detector.
For displays within detector enclosures, the Connect Node number is usually set to the associated
Detector Node number. In the example system:
Node 128 with have Connect Node 255
Node 126 with have Connect Node 253
Node 125 with have Connect Node 251
With Connect Node Specified:
1. The Connect Node is the default node that is displayed on power up.
2. A display can connect to any other detector on the network by selecting it from the list of
detectors.
3. Selecting any other node is permanent until changed by the user (or re powered).
With Connect Node Set to 000:
1. The logo screen is displayed on power up.
2. A display can connect to any other detector on the network by selecting it from the list of
detectors but will timeout after a short period.
3. A node found with Fire or Fault event is ‘caught’ and permanently connected until the event is
cleared or the connection is changed by the user.
Set up the number of Display and Detector units as required.
Network Faults
Any display units missing on the system reports as a Network Fault as shown. Check each display to
confirm connection.
When a detector unit is missing this is indicated towards the bottom of the display. Check which
detector is missing from the detectors found. See Section 3.4.
When a display is connected to a specific detector and communications are lost the fault is displayed
as above. Check the Detector is powered and check both the Display and Detector network wiring.
