Chapter 4 – Troubleshooting
G. The value of DOOR POSN (Point 32) does not change value when
the door position changes.
1. Verify that DOOR SWITCH (Point 28) is set to YES.
2. Check the wiring to the door contact switch and to the monitor.
3. Check continuity of the door contact switch when door is open and closed.
4. Check continuity of the wires between the door contact switch and the monitor.
5. Contact your local Siemens Building Technologies representative.
H. The Door Alarm is ON whenever the door is used to enter or exit the
room.
1. Check the value of DOOR DELAY (Point 22). Verify that the time entered allows a
person to pass through the doorway and the door to fully close.
2. Contact your local Siemens Building Technologies representative.
I. The monitored room is maintaining pressure, but the monitor keeps
going in and out of alarm.
1. Check the pressure limit points for the room. These values may need to be
changed.
2. Check the value for ALARM DELAY (Point 21). A greater value may be needed to
eliminate nuisance alarms.
3. Make sure the door is closed.
4. Verify that the mechanical system for the room is operating correctly and the
terminal box is providing sufficient supply and exhaust airflow.
5. Contact your local Siemens Building Technologies representative.
