Security: Intrusion

If there is no G in the panel's name, there is no ground fault detection and the panel does not have an S4 pin. If it has a single G in the name it has the chance it could be enabled if S4 is latched and under area 5 silent alarm relay there is a value other than 0. If it’s a GV2, GV3 or GV4 and S4 is latched, ground fault detection is enabled. If there is ground fault detection, latch S4 and measure DC voltage on Terminals 9 and 10: You should get 6.5-6.8 VDC Steady (not jumping around) when there isn't a ground fault. If there is a ground fault it can take up to a minute to display and clear at the keypad.

Causes: The heartbeat LED on the B426 is off. No communication failure, trouble or communication module missing error messages at the keypad. Solution Check the TMPR pins next to the Ethernet port on the B426.   Remove the jumper from the pins; the B426s heartbeat LED will start flashing to show the firmware version on the board and then it will resume normal or trouble operation depending on the condition on the B426. When the Tamper jumper is covering both pins the heartbeat LED is turned off to save power.

Possible causes and solutions: Ground Fault Detect enabled The control panel has a ground fault detection circuit that when enabled, detects ground faults on Terminals 1 to 9 and 11 to 30. If a ground fault condition occurs, the keypads annunciate a ground fault and control panel transmits a trouble message. Ground Fault condition is corrected When the control panel recognizes that the ground fault condition is corrected, and remains corrected for between 5 to 45 consecutive seconds, the control panel clears the fault from the keypad display and sends a restoral report   Measure earth ground (Terminal 10) and COMMON (Terminal 9) to determine whether the control panel has the necessary 0 VDC decay to -2.1 VDC. Measuring and comparing voltage for ground fault detection: Set your digital voltmeter (DVM) to measure VDC. Connect the red DVM lead to control panel Terminal 10, and the black DVM lead to Terminal 9. Compare this voltage to the following table: Enable Ground Fault Detect and reports To enable fault detection, use RPS. Set the following parameters: ·        PANEL WIDE PARAMETERS > Miscellaneous > Ground Fault Detection. Set to Enable ·        PANEL WIDE PARAMETERS > Report Routing > Burglar Reports > Trouble Report. Set to Yes. ·       PANEL WIDE PARAMETERS > Report Routing > Burglar Reports > Burg Restore (After Trouble). Set to Yes.

Test Reports can be set up from Teraterm or RPS (requires firmware 2.0 or above). The test report timer (re)starts when the panel item is changed or when the module reboots, once the timer expires the test report is sent. Step-by-step guide   Teraterm/RPS: Go to System Configuration > Test Report Settings > Test Report Interval The timer options are  Off, 4hr, 6hr, 12hr, or 24h
