Why does my Radionics Security System panel transmit PT BUS TROUBLE reports?
A short on the Data Expansion Loop or the ZONEX data terminals generates a PT BUS TROUBLE report. While the short remains, the panel responds as though the sensor loop for each point connected to the POPEX module was shorted. Check the wiring for shorts. Also, ensure all POPIT switches are set correctly.
What to do if points remain in trouble or alarm in my Radionics Security System when all devices are normal?
This can occur if the sensor loop is open, shorted, or grounded. Remove the sensor loop from the D7212 or POPIT and use a meter to check its continuity. The resistance should not exceed 100 ohms, plus the value of the end-of-line resistor on the wires. If the resistance is less than the value of the end-of-line resistor, inspect the wiring for shorts. With the wires for the loop detached, check their continuity to ground. A ground before the end-of-line resistor on an on-board point's sensor loop is interpreted as a short, while a ground on a sensor loop for a POPIT point is interpreted as an open.
How to fix a missing point on my Radionics Security System?
This issue can occur if the POPIT is not connected or is incorrectly connected to the data expansion loop. Disconnect the EOL resistor from the loop output of the POPIT and measure the voltage; it should be a constant 8 to 13 VDC. Another cause is if the sensor loop switch (1 to 8) is turned off on the OctoPOPIT. If the sensor loop switch on an OctoPOPIT is turned off for a programmed point, the point will report as missing. Also, ensure that only one OctoPOPIT with switch 12 ON is connected to ZONEX. If ZONEX is connected to a D8125, turn switch 12 OFF for all OctoPOPITs connected to that terminal. Finally, verify that the switches on the POPIT are set for the missing POPIT number, as incorrect switch settings can cause both missing and extra POPITs.
What to do if faulted points don't generate alarms on my Radionics Security System?
The D7212 ignores input from all points in the same area programmed for sensor reset during sensor reset (Command 47). Also, points programmed with the same address do not function correctly. Check to be certain that you have not duplicated point addresses.
Why do points intermittently appear as missing on my Radionics Security System?
This issue may be due to a problem with the data expansion loop. Refer to the section on 'Problems with Data Expansion Loop'. Another reason could be that the Debounce Count parameter is set at 1. Radionics recommends keeping the Debounce Count at the default value of 2. Decreasing it to 1 may cause points to appear as missing, while increasing it may cause missed alarms.
