Chapter 2 Operational Setup<br />
Configuration<br />
Note If the portal monitor is to have power supplied in conduit, install conduit<br />
at this point. Holes are provided at the right-hand rear corner at the top of the<br />
instrument for installation of 3/4” (19.05 mm) nominal conduit fittings. ▲<br />

The portal (<strong>PM</strong>-7) is flexible and can be configured in several ways. These<br />
include portal address, walk-thru operation, use of photoelectric switch, use<br />
of ultrasonic occupied signal and the tone-on-start of count cycle.<br />
Each of these items is selected (enabled or disabled), depending upon the<br />
position of the switches (SW1 and SW2) on the Master Annunciator<br />
printed circuit board.<br />
These switches contain eight individual rocker switches (1-8). The functions<br />
are ad indicated in the following figure. These switches are physically<br />
located near one end of the Master Annunciator printed circuit board, SWl<br />
is nearest to the center of the board.<br />
Portal Addressing:<br />
When several portals are installed at one facility, each should be given a<br />
unique address. By doing so the files kept by the portable laptop computer<br />
will be identified to each portal. Set the desired address of the portal by<br />
selecting the binary pattern of SW-1 switches 5 through 8 (SW-15-8).<br />
Walk-through Operation:<br />
The portal may be operated in one of two modes, Walk-through or pause<br />
and be counted. If the operating parameters are compatible with walt-thru<br />
operation, then use of the walk-thru mode is appropriate and switch SW2-1<br />
should be open. If however, the count time is excessive a pause and be<br />
counted mode may be more appropriate.<br />
The count time in the walk-thru mode should be such that the individual<br />
will e counted at least once, if not twice, as the individual walks at a normal<br />
speed through the monitor.<br />
If switch SW2-1 is closed then the monitor operates in a pause and be<br />
counted mode, requiring the individual to remain in the portal for a<br />
complete count cycle. The chime is used in this mode to signal the end of<br />
the count cycle. This notifies the individual that he may exit.<br />
