Fire Alarm Control Panels Appendices | en 119Other communications problems that can cause this condition include:1. Events occurring faster than the dialer can send them, which overflows the 32 eventbuffer,2. Programming errors such as missing phone numbers or account codes, over 100 Troublereports in 24 hours, or3. Other problems contacting a receiver.Check dialing type, format selection, phone numbers, account codes, phone line condition andtone programming (if tone burst formats are used).For more information, see Communicator Operation, 47.10.5.2Trouble PhoneSome troubleshooting tips for phone monitor problems are listed below:!Warning!High voltage!The voltage present during ringing for an incoming call can be over 100 VAC.1. Use a voltmeter to measure the voltage present across each phone line (Tip to Ring)while the phone line is idle. This standby telco battery voltage is typically in the range of30 VDC to 50 VDC, but any voltage above 5 VDC is accepted by the control panel. Thepolarity of the voltage does not matter.2. Check for other devices that might use the phone line, such as fax machines, credit cardverifiers or PBX systems. If the devices cannot be removed, ensure they are wired so thatthe control panel’s line seizure relay disconnects them when needed. Measure the linevoltage while these devices are in use. Ensure that it stays above 5 V.iNotice!NFPA 72 requirements mandate a dedicated phone line for fire reporting.3. Check for intermittent faults in the phone line. Make a test call and confirm that the lineis free of distortion and noise. Temporarily swap Lines 1 and 2 on the control panel andcheck if the problem indication moves to the control panel’s other phone line channel. Ifso, the phone line is causing the problem rather than the line monitor.4. Confirm that the fault message is phone fault and not com fault. Com fault is oftencaused by failing to program a phone number or account number for Phone Number 2while routing reports to Line 1, Backup Line 2. If only one phone number is available forreporting, set report direction for all events to phone 1 only. Com fault can also happen ifone of the phone lines has telco battery voltage, but does not complete a call. Make testcalls 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, theAuto-test report is sent on a different phone line each time it is sent. If only one phoneline is connected to the control panel, a Com fault is generated on every other test call.Bosch Security System, Inc. Installation and Operation Manual 2012.08 | 04 | F01U008458
