Integrated CAT-M1 communications module
The AC-250NXS includes an integrated CAT-M1 communications module, which
enables the meter to connect to public CAT-M1 cellular networks as scheduled,
during the installation and commissioning phase (typically once every 12 hours).
During communication, the device sends hourly interval data, daily consumptions
readings, meter and valve diagnostics to the Head End System.
When an alert such as high gas pressure or tamper condition is detected, the
meter immediately sends an alert to the Head End System within 15-seconds of
detecting the abnormal condition.
The device is incorporated with the ALWAYS ON feature which enables it to
receive requests from the Head End System. Apart from the device-initiated
communications, the Head End System can also trigger data communications
whenever necessary. This enables the remote valve shut off to be serviced
immediately to make sure of the safety in case of any emergency. The Head End
System can open the valve when the environment is clear, provided a person must
acknowledge physically when the valve is opened. The device can be reachable at
different time intervals – this can be configurable via the EDRX parameters.
