DS9400 Series Release Notes for Firmware V2.07 9.0 Known Issues with Firmware Version 2.07

•Temporarily swap lines 1 and 2 on the control panel and see if the problem indication moves to the control panel’s other phone line channel, in which case the phone line is causing the problem rather than the line monitor.

5.Confirm that the fault message is “phone fault” and not “Comm fault”.

•“Comm fault” is often caused by failing to program a phone number or account number for phone number 2, while routing reports to “line 1, backup line 2”.

•If only one phone number is available for reporting, set report steering for all events to “phone 1 only”.

•“Comm fault” may also be caused if one of the phone lines has Telco battery voltage, but will not complete a call. Make test calls to the receiver(s) on both phone lines, listening for the receiver ACK tone

6.Make sure 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 fault” will be generated on every other test call.
