Overview

Our pedestrian counting system, the LDA-CTR, tracks entries/exits and computes the current occupancy levels of a room or building.  The units are easy to install and simple to use.  Units may be doorway-mounted or free-standing, and the free-standing units can be used as either portable or permanent systems. Several pedestrian counters can also be linked together to provide a single counter output for multiple doors.

Features:

• Computes and displays current occupancy level
• Tracks and displays entry total
• LCD display w/ backlight button
• Reset key switch
• LDA-CTR units can be linked to provide single counter output for multiple doors
• Available as free-standing or doorway-mounted units

OPERATION

ENTRY
When a person walks through the sensing area in the entry direction, the output relay for the LDA-CTR sends an entry signal to the display module. Both the Total In and Occupancy counts are incremented.

EXIT
When a person walks through the sensing area in the exit direction, the output relay for the LDA-CTR sends an exit signal to the Occupancy display module. The Occupancy count is decremented, the Total In count does not receive a signal.

LINKED DOORWAYS
Each LDA-CTR has a "Link" input which can be connected through a "Link Module" to the relay outputs of a previous LDA-CTR. The link passes the entry and exit signals through the LDA-CTR circuit board. This allows several doorways to be monitored and counted by a single display unit.
