Hach sc200 - Adding an Expander (B1292); Concentrating Remote Alarms

PAGE 42 PROGRAMMING EXAMPLES
When one of the remote units is alarmed, it will send its alarm ON output code over the radio. This code will be
interpreted as a remote alarm input code at the central unit. This will initiate the B1290 to send its alarm report over
radio and telephone. As part of its alarm sequence over radio, the B1290 will send its alarm On output code. This
code will be interpreted as an acknowledgment by the remote, and it will stop sending the alarm. The central unit
will continue to report over radio and telephone until it is acknowledged.
