DOUBLE EGREES:
Perform the following set up using LCN's remote control to reduce cross talk between duel egress applications. Refer to
REDUCING
the figure on page 2 to ensure the two Presence Sensors are installed with at least 40" of separation when measured
CROSS TALK
between the centerline of each sensor.

LCN'S UNIVERSAL
REMOTE
The Presence Sensor is fully compatible with LCN's Remote Control as shown below. Use of the remote control should
CONTROL
be conducted within 10' – 15' of the sensor, and the remote should be pointed directly at the sensor when used. Refer to
the "Programming Guide" in the following section for each parameter and its values.

Place doors in the hold open position. Unlock sensor and set open door Pattern Depth to 5 (Medium Pattern).
This sequence will turn off threshold IR while door is in open position. This function should be changed on both
sensors:

The infrared frequency function may need to be changed. Change frequency on one of the sensors:

then
Change to a different mode in applications where high gloss floors or multiple doors are installed in vestibules.
Change sensor one to:

Change sensor two to:

The Presence Sensor is capable of having two patterns (door closed and door open) that are
independently adjustable. Thus, when programming, it is necessary to adjust the pattern for door closed,
and then to adjust the pattern again when the door is open. The following functions may be
independently adjusted for each door position:
Sensitivity
Pattern Width
Pattern Depth
The following functions apply to both door closed and door open positions:
Automatic Learn Time
Immunity
Frequency
Output Configuration
Door Control Mode
Hold Time
Interface Type
The immunity modes include Rain Mode and Snow Mode. During these modes, learn time of the sensor
will not be affected. These modes affect the interpretation of the objects in the field of detection relative
to the background.
