Door Sensor
• The door sensor contacts are used for the forced door and propped door features.
• Connect the door sensor as shown below.
• The door sensor circuit provides a feature to work with a special type of door sensor, that is tamper proof. This
prevents an internal security breach, where someone with authorized access to an area could potentially short-
out the contacts on the door sensor. If used with the anti-tamper door sensors, the jumper of SW SEL (JMP1)
must be set as follows.
