6 Diagnostics and Troubleshooting
6.1 Phone monitor troubleshooting
Comm Fail/DATA LOST
A common cause of this fault condition is failing to program Phone/IP Number 2 or Account
Number 2. If report steering is directed to use Phone/IP 2 as Backup, reports made to an
unprogrammed Phone/IP Number 2 or Account Number 2 warn the installer that Phone/IP
Number 2 is not available.
Other communications problems that can cause this condition include events occurring faster
than the dialer can send them which causes the 32 event buffer to overflow, or other
problems contacting a receiver.
Check the dialing type, format selection, phone numbers, account codes, phone line condition
and tone programming (if tone burst formats are used). For more information, see
Reporting
Requirements, page 40 .
Some troubleshooting tips for phone monitor problems are listed below:
1.
Use a voltmeter to measure the voltage present across each phone line (Tip to Ring)
while the phone line is idle.
The voltage present during ringing for an incoming call can be more than 100 V AC.
The standby telco battery voltage is typically in the range of 30 V DC to 50 V DC, but any
voltage above 5 V DC is accepted by the control panel.
The polarity of the voltage does not matter.
2. Check for other devices that might use the phone line, such as fax machines, credit card
verifiers or PBX systems.
If the devices cannot be removed, ensure that they are wired so that the control panel's
line seizure relay disconnects them when necessary.
Measure the line voltage while these devices are in use. Ensure that it remains above 5 V.
3. Check for intermittent faults in the phone line.
Make a test call and confirm that the line is free of distortion and noise.
Temporarily exchange Lines 1 and 2 on the control panel and check if the problem
indication moves to the control panel's other phone line channel. If so, the phone line is
causing the problem rather than the line monitor.
4. Confirm that the fault message is LINE 1 Disconnect (or LINE 2 Disconnect) and not Pri
Acct Comm Fail (or Sec Acct Comm Fail).
A Comm Fail can also occur if one of the phone lines has telco battery voltage, but does
not complete a call. Make test calls to the receiver(s) on both phone lines, listening for
the receiver ACK tone.
5. Ensure that two phone lines are available.
In accordance with NFPA requirements, the Auto-test report is sent on a different phone
line each time it is sent. If only one phone line is connected to the control panel, a Comm
Fail is generated on every other test call. See
Reporting Requirements, page 40 .
6.2 Diagnostics Data and System Information
Auto/Manual Test Report
Any user authorized to enter test menu (Level 2 by default) can initiate transmission of manual
test reports to central station accounts. The Report Steering option allows for programming to
which central station manual and auto test reports are sent. For a manual test report, the user
selects either phone line or IP address to send the test report. The panel provides options for
all possible combinations of phone lines and destinations and all IP paths to send the manual
test report. Every communication failure is logged in the history.
