EIA-485 Communications Trouble Report
The UNI•COM supervises the integrity of the information received from the FACP
via the EIA-485 communications bus. Should the communications bus malfunction,
the UNI•COM transmits the report '485 comm trouble.' When the communications
bus returns to proper operation, the UNI•COM will report '485 comm trouble
restoral.' The EIA-485 communications bus is supervised when the UNI•COM is
configured for receive only or receive/transmit operation.
Manual Test Report
By pressing the TEST key three times in rapid succession, the UNI•COM will
transmit a manual test report to the UCS. The TEST key may be pressed at any
time. The Serviceman Code is not required.
Program settings for zone or point reporting must match in both the host FACP and
the UNI•COM. Refer to the Unimode 200 Technical Manual section on Level One
programming for instructions on setting the FACP for zone or point annunciation.
Refer to Section 3.3 of this manual for instructions on setting addresses 50 through
54 and 61. Also refer to Section 4.3 for a discussion of Type Mode.
Zone/Point Fire Alarm Report
The UNI•COM reports activated status of specific zones or points defined as fire
alarm. Fire alarm devices include smoke detectors, pull stations, waterflow devices,
heat sensors, etc. The report transmitted includes the fire alarm message and the
identity of the activated zone or point.
Note: Use the Type Mode to identify all supervisory devices installed in the system
to the UNI•COM. Refer to the Type Mode instructions in Section 4.3.
Zone/Point Supervisory Activation Report
The UNI•COM reports activated status of specific zones or points defined as
supervisory. The report transmitted includes the supervisory alarm message and the
identity of the activated zone or point.
General Fault Report
The general fault report is transmitted for most types of system trouble conditions
including the following:
• Zone/point trouble
✓ Maintenance alert
✓ Wrong device
✓ Improper device
✓ Improper address
✓ Auto-detector test failure
✓ No response
✓ Shorted or open initiating device circuit
• Main SLC loop fault
• Earth fault
• Reverse polarity/city box trouble
• Memory corruption
• Disabled point
• Off-line programming
• Annunciator trouble.
Note: When a zone or point is in trouble, transmitted messages include the specific
zone or point trouble report and the general fault report (unless disabled).
A general fault report is not sent for AC loss and EIA-485 failure. These trouble
conditions are transmitted as individual trouble reports.
