3.5.4.5 Enable Right Detections
If this control is unchecked, Right sensor (Passive Infrared or Magnetic)
detections will be ignored. When checked, detections will be processed based on
the PT-210M operating mode:
Qualify Mode off: The RIGHT event code will be transmitted.
Qualify Mode on: A qualified detection will transmit the QUAL event code.
If a SEISMIC detection is involved, QUAL/VEHICLE or QUAL/PEDESTRIAN
event codes will be transmitted.
3.5.4.6 Directional Mode
When the Directional Mode button is checked, the
LEFT and RIGHT sensors are configured to work
together, allowing activity from left-to-right or right-
to-left to be detected.
Note: This mode of service is not available when
Qualify mode is enabled.
3.5.4.7 Number of Sensors
When using Passive Infrared sensors in Directional Mode, you have the option of
using either 1 or 2 physical sensors. Directional mode using a single IF-520 or
IF-540 is possible because the passive infrared sensor contains two sensing
elements each producing a field of view. However, with one sensor, the angle of
the dead zone separating the two fields of view is rather narrow (approximately 3
degrees). To increase deployment flexibility, the use of two sensors is
recommended. When using a single sensor in directional mode, select 1. When
using two sensors in directional mode, select 2.
Note: The selection of one or two sensors applies to Passive Infrared sensors only.
Magnetic sensors must be used in pairs.
3.5.4.8 Enable Left-To-Right Detections
If this control is unchecked, left-to-right detections will be ignored. When
checked, left-to-right detections will be processed within the limits imposed by
Left-To-Right Minimum Delay and Directional Maximum Delay.
