Features of SNS Battery-powered Sensor Devices
The service button has several uses depending on the status of the sensor device.
•
Activating the service button causes the sensor device to check in with the AMP.
•
During an alarm, activating the service button cancels the alarm and stops the LED from
flashing but does not acknowledge the alarm on the AMP. Activating 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
LEDs are visual indicators of sensor device status and sensor readings. The sensor device also
communicates its status using beeps.
LEDs
Sensor devices have an LED visible from outside the sensor that indicates sensor status, as shown
in Figure 10. Sensor devices also have an internal LED that may be useful for troubleshooting, as
shown in Figure 4, Figure 11, and Figure 12.
