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.
The heartbeat LED on the B426 is off.
No communication failure, trouble or communication module missing error messages at the keypad.
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.
Output A can be configured as a Form C, Com reference or as a Dry contact depending on how you put the jumper under the panel cover.
This article will help you to find out how you can configure output A (1) on the B Series Panel.
When the B420 or B426 has been programmed through the web interface and the setting; Panel Programming Enable has been set to NO, the B420 or B426 Ethernet Communicator module programming screen will look as displayed below with programming parameters not available for changing.
The card will need to be accessed again through the web interface and Panel Programming Enable must be changed to read YES.
Log into the Web-Browser and select Maintenance. Click on the drop-down arrow beside the field; Panel Programming Enable and change it to Yes.
When programming the B420 or B426 to be connected to a GV3 or older panel the web interface is used.
When programming the B420 or B426 to be connected to a GV4 panel, use keypad programming.
1 Select Panel Wide Parameters:
2 Under Panel Wide Parameters > Select Communicator:
3 Change your Primary Path Device to Cellular IP Path 1:
4 Next, go to Enhanced Communication:
5 Double-Click the Network address to input your Central Station Receiver’s IP address.
6 Set your Supervision Time.
Note: this should also match what is in your central station receiver to eliminate erroneous communication trouble.
⚠️ Be sure to notify you Central Station to add your area 1 account number, supervision rate and enable the receiver for Re-synchronization.
Are Radion Wireless and B Series Keypads compatible with D7412Gv4/ D9412Gv4/ D7212GV4 Control Panels?
Radion Wireless and B Series Keypads are only compatible with D7412GV4 and D9412GV4 on firmware ver 2.0 or newer panels.
D7412Gv4 or D9412Gv4 ver 1.0 can be upgraded to ver 2.0, however older SDI keypads will lose most of their functionality as part of the upgrade
The D7212GV4 CANNOT be upgraded. Hence it will never be compatible with either of those devices.
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.
Go to System Configuration > Test Report Settings > Test Report Interval
The timer options are Off, 4hr, 6hr, 12hr, or 24h
How to configure the output in GV4 ver.2?
Selections: 0 to 8 (increments of 1)
Use this parameter to activate an output when the point goes into alarm.
The output does not activate for Trouble nor Supervisory events. Reset the output by clearing the memory from the keypad display.
The outputs used can be on an output module installed on either the Zonex bus or the SDI2 bus.
*Notice that the Relay will activate only when the point goes in to alarm, not when it changes to an off-normal state.
Follow the steps from this article to accomplish the BFSK relay functionality.
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.
