SET-UP
Without the LCN Remote Control, the Presence Sensor may be set up using the manual push buttons (see
diagram below) located under the right end cap. Only the sensitivity, relay mode, auto-learn time, pattern width,
and pattern depth may be adjusted with the manual push buttons. To adjust the Presence Sensor, complete the
following:
1. To start the set-up process, press PB1 (for less than 2 seconds)
The set-up function will be launched according to the current door position. The green LED will flash at
2+/- Hz for 10 seconds. This LED will stop flashing once a successful set-up is achieved.
If there is an interruption to the field of detection during this procedure, the green LED will flash at a slower
rate. Press PB1 to re-launch the set-up.
2. To change the detector’s parameters, press PB1 (for more than 2 seconds), then release.
3. Press either PB1 or PB2. The LED will immediately flash red, followed by a sequence of green flashes.
4. The red flashes indicate the parameter and the green flashes indicate the setting of the particular parameter.
NOTE: Pressing PB1 will toggle between the parameters and pressing PB2 will toggle between the range of
adjustments for that particular setting. Once you achieve the highest adjustment, the value will roll over to the
lowest setting, upon the next press of PB2. A zero value will result in no flash of the LED.
To exit manual set-up, simply wait 20 seconds or press PB1 for more than 2 seconds. Replace the right end cap
back on the Presence Sensor.
Use the chart below as a reference for the manual set-up process.
