Problems with Points (Continued)

Symptom

Diagnosis	Remedy

One or more points remain in trouble or alarm with

all devices connected to the sensor loops normal.

The sensor loop is open, shorted, or grounded.

Opens,shorts, or grounds cause troubles or alarms depending on point programming.

Remove the sensor loop from the D9112 or POPIT and meter it for continuity. There should be no more than 100• resistance, plus the value of the end of line resistor on the wires. If you meter less resistance than the value of the end of line resistor, check the wiring for shorts.

With the wires for the loop removed, meter them for continuity to ground. A ground before the end of line resistor on an on-board point's sensor loop is interpreted as a short. A ground on a sensor loop for a POPIT point is interpreted as an open.

Faulted points do not generate alarms or troubles as programmed.

Panel transmitts 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.

Command 47 pressed at the time the alarm or trouble was generated.

Two points are programmed with the same address.

Short on D8125 POPEX module’s Data Expansion Loop or short on D9112’s ZONEX data terminals (25 & 26, or 27 & 28).

A POPIT has its switches set incorrectly and it’s sensor loop is shorted.

The D9112 ignores input from all points in the same area programmed for sensor reset during sensor reset (Command 47).

Points programmed with the same address do not function correctly. Check to be certain that you have not duplicated point addresses.

A short on either 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 wiring for shorts.

Check to be certain all POPIT switches are set correctly.

An OctoPOPIT assigned to points 65 to 71, or 129 to 135 has switch 8 turned on. Sensor loop is shorted

Check to be certain that switch 8 is turned of for any OctoPOPIT assigned to points 65 to 71 or 129 to 135.

The D9112 reserves points 72 and 136 for monitoring the ZONEX Point Bus (Data Expansion Loop).
