Ingersoll-Rand 7940-8770 Double Egrees Reducing Cross Talk, LCN’S Universal Remote Control

Page 6

DOUBLE EGREES: REDUCING CROSS TALK

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

1.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:

+ + then +

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

+ + then +

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

+ + then +

Change sensor two to:

+ + then +

LCN’S UNIVERSAL REMOTE CONTROL

The Presence Sensor is fully compatible with LCN’s Remote Control as shown below. Use of the remote control should 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.

Additional program notes:

1.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:

ƒSensitivity

ƒPattern Width

ƒPattern Depth

2.The following functions apply to both door closed and door open positions:

ƒAutomatic Learn Time

ƒImmunity

ƒFrequency

ƒOutput Configuration

ƒDoor Control Mode

ƒHold Time

ƒInterface Type

3.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.
