Features of SNS AC-powered Sensor Devices
Figure 3: Service Button, Display, and LED on AC-Powered Temperature Sensor (SNSATPD)
The service button has several uses depending on the status of the sensor device.
•
To enable browser-based configuration, pressing and holding the service button while plugging
in the sensor device causes the device to enter configuration mode.
•
During normal operation and discovery and auto-configuration, pushing the service button
causes the sensor device to sound the beeper and check in with the AMP.
•
During an alarm, pushing the service button cancels the alarm and stops the LED from flashing
but does not acknowledge the alarm on the AMP. Pushing the service button during an alarm
also does not sound the beeper or cause the sensor device to check in with the AMP.
Visual and Auditory Interfaces
The display and LED, shown in Figure 3, are visual indicators of sensor device status and sensor
readings. The sensor device also communicates its status using beeps.
Display
Table 6 describes the display functions for AC-powered sensor devices.
