D9412G/D7412G/D7212G Troubleshooting 3.0 Troubleshooting 3.1 Introduction Bosch Security Systems provides this guide to help troubleshoot problems with the D9412G/D7412G/D7212G. To prevent problems from occurring, read the preceding sections of this guide and the panel’s Program Entry Guide to verify that the panel is correctly installed and programmed. 3.
D9412G/D7412G/D7212G Troubleshooting Symptom SERVC GND FAULT appears in command center displays. Diagnosis The panel has detected an earth ground fault. SERVC KEY PAD appears at other command centers connected to the panel.and the panel transmits an SDI FAILURE report to the receiver. SERVC 9210 #n appears at the other command centers connected to the panel and the panel transmits an SDI FAILURE ## report to the receiver.
D9412G/D7412G/D7212G Troubleshooting 3.4 Problems With Command Centers Symptom Command centers show erratic behavior. For example, the pip that confirms you pressed a key echoes. NO AUTHORITY displays at the command center when you enter your passcode to perform a function. Diagnosis Remedy More than one Use a supervised address in one command center only command center has or use a different supervised address for each the same supervised command center. address.
D9412G/D7412G/D7212G Troubleshooting 3.6 Communication Failure The panel goes into Communication Failure after ten unsuccessful attempts to reach the receiver. Follow the procedure in Section 3.5 Phone Line Trouble on page 11 to verify that there is no problem with the phone lines at the installation. If the phone lines are good, monitor the lines (preferably at the receiver) for the symptoms listed below.
D9412G/D7412G/D7212G Troubleshooting 3.7 Problems with Points If the switches on a POPIT are set incorrectly, it may create both a missing and extra point. When a missing point is found, perform a Service Walk Test to search for extra points. See the Owner’s Manual for test instructions. Symptom Point appears as missing at command centers and in reports to the receiver. Diagnosis POPIT is not connected or incorrectly connected to the data expansion loop.
D9412G/D7412G/D7212G Troubleshooting System Panel transmits PT BUS TROUBLE reports. Erroneous alarm and/or trouble reports may follow PT BUS TROUBLE report. Erroneous alarm and/or trouble events for off-board points appear at command centers. All off-board points are MISSING. Keyswitch points (P## Type is programmed as 4, 5, 6, 7, or 9) report as missing. If area is armed, the point reports a MISSING ALARM. If the area is disarmed, the point reports a MISSING TROUBLE.
D9412G/D7412G/D7212G Troubleshooting 3.8 Problems with the D8125 POPEX Data Expansion Loops EMI (Electro-magnetic Interference), excessive resistance, or intermittent grounds, shorts, or opens on the data expansion loop can cause erratic or intermittent functioning of points. If EMI may be a problem, see Section 3.9 EMI on Long Wire Runs on page 16. AC induction on the data expansion loops must be less than 1.0 VAC.
D9412G/D7412G/D7212G Troubleshooting 3.9 EMI on Long Wire Runs EMI (ElectroMagnetic Interference) can cause problems on long wire runs for serial devices (command centers, POPITs, etc.). The use of shielded cable reduces the effect of this interference. Some potential sources of noise on a long wire run include: • Radio or television transmitter site. • Ham radio operator’s transmitter site. • Computer network system. • Heavy machinery (large electrical motors). • PBX telephone system.
D9412G/D7412G/D7212G Troubleshooting 3.12 Watchdog Reset Reports The panel sends a WATCHDOG RESET report whenever the panel's CPU (Central Processing Unit) is interrupted and has to start its normal operating sequence over. The on-board buzzer sounds briefly during the Watchdog Reset. The panel returns to normal operation immediately after resetting. The most common cause of CPU interruption and WATCHDOG RESET reports is static discharge to the panel.
D9412G/D7412G/D7212G Troubleshooting • With the overload removed, the panel returns power to Terminals 3, 6, 7, 8, 24, and 32, and the Programming Connector. The panel sends PT BUS RESTORAL and SDI RESTORAL reports. • If a D928 Module is connected, it stops sounding. • If the battery voltage is below 8.4 V, the panel does not reconnect it. The battery must be replaced. • When the battery reaches 13.7 V, the panel sends a BATTERY RESTORE report and turns off the red Low Battery LED.

D9412G/D7412G/D7212G Troubleshooting 3.16 Ground Fault If a D9412G/D7412G/D7212G system detects a Ground Fault, considered as a high impedance fault to earth ground of approximately 100 kΩ or less, the control panel’s command center displays SERVC GND FAULT. Use the following troubleshooting procedure as a general guideline in identifying and isolating the cause of the earth ground fault. Please read this procedure carefully before trying to identify the cause of the Ground Fault. IMPORTANT 3.16.
D9412G/D7412G/D7212G Troubleshooting 5. Once the voltage has been determined, remove the wire(s) from the terminals listed and verify the voltage on Terminals 9 and 10 is approximately 6.5 to 6.8 VDC. If the voltage does not measure within this range after removing the suspected wire, continue to check the remaining wires connected to the terminal group. To verify that the wire removed has an earth ground short, disconnect the DVM and switch the DVM to read Ohms.
