If the sensor is an analog sensor and a
corresponding module is installed in the
controller, refer to the instructions supplied
with the Network or Sensor Module.
Make sure the digital connector wiring
harness is seated on the inside of the door
assembly and that the wiring harness is not
damaged.
If the digital sensor is connected to the
controller with a digital termination box, user
supplied junction box, digital extension
cables, or a user-supplied extension cable,
connect the sensor directly to the controller
and perform a device scan. If the controller
recognizes the sensor, check that all the
wiring in the junction boxes or extension
cables is correct.
Make sure that only two sensors are installed
in the controller. Although two analog module
ports are available, if a digital sensor and two
analog modules are installed, only two of the
three devices will be seen by the controller.
