TIPS
The sensor must be
firmly fastened to
prevent vibration.
The LCN Presence Sensor (PN: 750182-00) is a self-monitored ready overhead-mounted diffused active infrared
sensing device that provides detection for the triggering of automatic swing door safety functions. When used with
LCN’s lockout devices, the sensor is programmed to allow two different fields of detection - one for detection when
the door is in the fully closed position and the other for detection when the door is fully open. While the door is in
the fully open position, the Presence Sensor extends its coverage back through the threshold area of the doorway,
to provide coverage that will overlap with LCN’s motion sensors.
As with all of LCN’s programmable sensing devices, full adjustability is achieved with the use of LCN’s hand-held
remote control unit. This allows alteration of all of the available functions as well as for inquiry of existing settings.
Should the need arise; the Presence Sensor may also be tuned by means of two sensor-mounted buttons
contained on the PC Board within the unit. With these two buttons, the Presence Sensor’s field of detection can be
altered without the use of the hand-held remote. If a complete door-mounted safety sensor (DMSS) system is not
used in addition to the Presence Sensor, LCN recommends the use of a lockout safety beam to allow safety
signaling if the zone is entered during a door closing cycle.
