Example 1: Reporting Alarms over Radio and Telephone
In this example, assume that your company has a mobile radio system which is monitored by field personnel. Radio
operators have DTMF pads on their mics so they can acknowledge an alarm from the B1290. They would like to
have the alarm reported over the radio system three times with a 2 minute interval between transmissions, then
dialed out over the telephone if it is not acknowledged. If the alarm is not acknowledged, the B1290 should try
again in ten minutes. After six tries at ten minute intervals, the B1290 should switch to trying once an hour. The
COS on the radio used with the B1290 gives a high signal when the channel is busy.
