Initializing the APD Device and Setting the Range
The APD device takes two minutes to learn the background and initialize after it is powered on or the detection
range is reset. It is strongly recommended that no people are in range of the device during the initialization as
this may affect sensitivity.
While the device is initializing, the LED light on the front of the device will blink. As soon as it is initialized, the
LED light will stop blinking.
After initialization is complete, the sensor will detect a person in 2-3 seconds and the blue LED will go on (and a
presence-signal will be sent by the device). When there is no presence detected the blue LED will go off (and a
no-presence signal will be sent). Normally when a person is no longer detected it takes the sensor 1 minute to
verify this. However to facilitate installation only, a range test mode is available.
Range-Test Mode
In Range-Test Mode, when a person is detected, the sensor will still activate in 2-3 seconds, but when a person
is not detected the sensors will deactivate in less than 5 seconds, providing almost immediate feedback to the
installer. When a change is made to the range while in range-test mode initialization is reduced to 30 seconds,
instead of the 2 minute initialization required in normal mode. Use range-test mode to test the outer range of the
detection area (the area for larger movement).
NOTE:
Range-Test Mode is not as sensitive to fine movement, such as respiration, as is the normal mode and it
should only be used for installation purposes.
Using the Range-Test Mode Step-by-Step
Range-Test Mode can be enabled and disabled in the APD WebUI.
To set the range of the APD device, use the following procedure:
1. Use a remote workstation on your network to connect to the APD WebUI and navigate to the Presence
Detection page of the Setup tab.
2. Click the
Enter
button to enable Range-Test Mode.
3. Use the diagrams
Positioning the APD™ Device
on page 4 as a general guideline to choosing an initial
setting on the Detection Range slider.
4. Test the actual range being detected by doing a walk-test to different areas of the room and determine if
you are being detected or not. Testing the actual range detected in your environment is important to
correctly setting up the sensor.
5. Depending on your results, either skip to step 8 or adjust the Detection Range setting again.
When you change the Detection Range setting in range-test mode the sensor re-initializes. In Range-Test
Mode this initialization is reduced to 30 seconds.
6. Test the detection range again by continuing your walk-test. If the results of your walk-test are not
satisfactory continue the walk-test and adjust the range.
