P/N 06-236530-001 5-9 August 2013
Addr Communication Fault On A loss of communications between
the SLC's driver circuit and the
device at address Addr.
• Check device connections to wiring
• Ensure that device has not been
removed
• Check SLC wiring for excessive
capacitance and/or resistance if the
device LED is blinking. Refer to
Paragraph 2-8.1. Rewire using
recommended wire in Appendix B.
• Replace the device if above
procedures are unsuccessful.
Addr Detector Tbl On ORION-XT
Interface Module
A problem in a high-sensitivity smoke
detector (HSSD) being monitored by
a PALM
• Check the PALM-to-HSSD
connections
• Use OCS to troubleshoot the HSSD.
• Refer to ORION-XT Installation,
Operation, and Maintenance
Manual, P/N 89.200.
Addr Drift Fault On Device Type The inability of a SmartOne smoke
detector to further compensate for
reference signal variation
• Globally isolate all outputs. See
Paragraph 3-2.5.2.2.9.
• Disconnect smoke detector from
SLC and visually inspect for
damage. Clean the detector as
recommended.
• Use Handheld Programmer to test
the device. Refer to Appendix D.
Reconnect device to SLC.
• Measure the detector sensitivity.
See Paragraph 3-2.5.2.3.6.
Replace the detector if the clean-
air reference value is more than
one half of the alarm-threshold
value.
• Conduct an initiating device test on
the detector. See
Paragraph 3-2.5.2.5.1.
• Activate and confirm a proper
alarm response from the detector.
• Replace device if any of above tests
is unsuccessful.
• Globally de-isolate all outputs. See
Paragraph 3-2.5.2.2.9.
