Having an out-of-band mechanism to raise alarms through is an important function of any critical system. Traditionally, sending alarms via an SMS ‘text message’ had to be accomplished via an RS232 connected GSM modem with the Tridium SMS Service. More common now however is to find a Teltonika 4G/5G modem connected to a Niagara system via TCP/IP network for data connectivity requirements. ossTeltonikaSMS leverages the onboard API of the RutOS software running on most Teltonika RUT series routers and presents a familiar Alarm Recipient component in your Niagara instance that will send alarms via a network connected Teltonika router. No need for a separate RS232 GSM model anymore!
