1. Allow the door to open in the automatic 

mode. Unlock the Presence Sensor and 
launch a setup by pressing the Setup key, 
followed by the number 2. If the sensor 
does not begin flashing green, and instead 
goes back to a red indication, improper data 
exists. Refer to respective lockout User’s 
Guide for troubleshooting. 

2. Check for proper polarity at terminal 6 and 

7.  The negative wire from the lockout 
(white) should be connected to terminal 6, 
and the red/white striped wire from the 
lockout should connect at terminal 7. 

‰ HELPFUL HINT: If faulty data is suspected, 

simply power the door to the open position 
(by activation OR with the use of a hold 
open switch). While the door is open, 
unlock the Presence Sensor, and press the 
setup key, followed by the number 2. If the 
sensor goes back to a red LED (as opposed 
to flashing the green LED to indicate a 
setup), there is a strong probability that the 
data is incorrect. Refer then to the 
respective lockout User’s Guide for 
troubleshooting help. 

Presence Sensor 
repeatedly re-learns the 
environment with each 

1. Improper data from the lockout 

device 

2. Data polarity at the Presence 

Sensor is incorrect 

Presence Sensor not 
reacting to the remote 
control 

1. Batteries in the remote control are 

dead. 

2. Distance between sensor and 

remote is too far. 

1. Replace batteries in the remote control 
2. 

Move in closer to the sensor when 
programming.  

3. If remote control fails, manual programming 

procedures may have to be used. See page 
8.  

‰ HELPFUL HINT: Use LCN’s Spotfinder to 

test the output of the remote control. Simply 
point the remote at the IR Spot on the 
Spotfinder, press the Unlock key on the 
remote, and red LED should illuminate.
