AMX NXD-500i Making the most of the Light bargraph, Making the most of the Motion Sensor feature

Setup Pages and Descriptions

Sensor Setup Page Elements (Cont.)

Wake On Motion: The Wake Panel Sensitivity relates to the sensitivity of the motion sensor to detect motion and wake the panel accordingly.

	• Toggle the Enable/Enabled button to either active/inactive this feature:
	- Enable - activates this feature. Activating this feature reactivates the panel
	from a panel timeout (sleep) mode.
	- Enabled - (illuminated when selected) deactivates this feature and makes
	the panel use the specified Display Timeout value set on the Setup Page.
	• Use the Wake Panel UP/DN buttons to alter the sensitivity value.
	- Range = 0 - 100.
	• The horizontal WAKE PANEL SENSITIVITY bargraph indicates the current
	motion sensitivity value associated with waking the panel from a timeout.
Motion:	The Motion bargraph displays a vertical bargraph indicating the current value of
	the motion detected by the on-board motion detector.

Making the most of the Light bargraph

By setting a certain minimum or maximum amount of light to be received by the device, the Light bargraph may be used to trigger particular commands in NetLinx. The red line on the Light Sensor bargraph is the threshold level. It is used to determine the level of light at which to activate the Light Sensor Channel. The channel is activated when the light level is below the threshold and deactivated when above the threshold. For more information, refer to the Programming section on page 77.

Making the most of the Motion Sensor feature

The motion sensor works by detecting the heat of objects passing by the front of the touch panel. Because of this, the sensor works best when detecting lateral movement, such as when a person walks in front of the touch panel from left to right. This appears in the Motion Sensor bar based on the signal strength: a hand waved directly in front of the motion sensor is going to produce a stronger signal than a person walking by at the outer range of the sensor. The sensitivity may be modified by environmental conditions, such as increased body heat or outside heat sources such as sunbeams or heater vents. To set the Motion Sensor to best effect:

1.Ascertain the intended sensitivity of the Motion Sensor. For instance, check to see if commands are to be initiated by someone walking past the touch panel, if someone enters the room at the edge of the touch panel’s range, or if someone specifically reaches for the panel’s face.

2.Open the Sensor Setup page (FIG. 51) from the Protected Setup menu section.

3.Watch the movement of the Motion Sensor bar while holding perfectly still. This allows tracking of other factors that might affect the Motion Sensor, such as air conditioner vents or moving curtains.

4.Copy the movement intended to set off the Sensor while watching the Motion Sensor bar, such as walking past the device. In particular, watch for the spikes in the bar where the sensor picked up the most movement.

5.Set the Motion Sensor bar to the desired sensitivity, making sure that it is located below the spikes previously noted. If the bar is set above the level of the spikes, the Motion Sensor may never be set off by that level of motion.

6.Repeat the movement and check to see if the movement exceeds the bar setting. Adjust the bar as necessary to set the desired sensitivity.
