Configuring Presence Mode Modifier
The behavior of a channel operating in presence mode may adjusted by applying
one of the following modifiers:

Delay – defers the onset of the contact closure by a specified duration. If a
vehicle moves off of the sensor before the specified delay expires, the contact
does not close. Delay is expressed in seconds from zero to 31.

Extension – increases the duration of the contact closure by a specified
increment. Extension is expressed in half-seconds from zero t0 7.5.
The modifiers do not apply to channels operating in pulse mode.
Configuring Channel Holdover Duration
The Channel Holderover parameter allows an extension to the channel holdover
duration when it is activated by the events from a particular sensor. Values from
0.0 to 0.75 are available for selection.
Defining Sensor-to-Channel Mappings
To map sensors to an APCC or EX card, perform the following steps:
1. Select a sensor from the image map.
2. Open the Card Addresses window by clicking the Card Addresses tab.
The Extension entry extends the duration of an APCC or EX card on a per-sensor
basis. The Delay entry delays the duration of an APCC or EX card on a per-sensor
basis; these entries are optional.
The shelf number-slot number is a card address associated with an APCC or EX
card, and channel is between 1 and 4.
