SIP-CB can count low frequency pulses from up to four independent sources over specific periods of time. At the end of each time period, it saves the total counts in its memory and starts again. At regular intervals, or on demand, the SIP-CB establishes a radio link with a GSM cellular telephone service provider and transmits its stored information to a central computer system for processing.
Alternatively, any of the four pulse-counting inputs can be configured to monitor alarm or status conditions. SIP-CB also has another four inputs dedicated to alarm or status processing only. It is, therefore, capable of monitoring up to eight alarm or status conditions. SIP-CB can be programmed to place an immediate call to alert users in case of an incident or simply report it on the next scheduled call.
