Configuring a DPX Contact Closure Sensor
Before using DPX-CC2-TR to detect contact closure status, water, smoke
or vibration, you must determine the normal state by adjusting its dip
switch. The dip switch controls the LED state on DPX-CC2-TR, and is
associated with a channel.
To adjust the dip switch setting:
1. Place the detectors/switches connected to DPX-CC2-TR to the
position where you want to detect a specific environmental situation.
2. Uncover the dip switch on DPX-CC2-TR.
3. To set the Normal state for channel 1, locate the dip switch labeled
1.
4. Use a pointed tip such as a pen to set the slide switch to the position
labeled N.O or N.C.
 N.O (Normally Open): The open status of the connected
detector/switch is considered normal. An alarm is triggered
when the detector/switch turns closed.
 N.C (Normally Closed): The closed status of the connected
detector/switch is considered normal. An alarm is triggered
when the detector/switch turns opened.
