RFC-1 Basic Operation page 5.7
If there is not a generator and a UPS is not used, when AC power fails at a site, both the RFC-1 and the transmitter
lose power. When power returns, the RFC-1 makes a new reference scan. If the transmitter does not power up
automatically, the reference scan will show that the power off condition is normal and no alarm will trigger. Use the
power failure alarm to avoid this situation.
Instruct all personnel who will receive alarm calls from the RFC-1 about the various alarms and associated channel
numbers. They need this information so that they can respond appropriately to the alarms.
5.5 Clock and Calendar
Setting the clock and calendar allows the RFC-1 to report the time and date when an alarm occurs. The clock and
calendar are also used to trigger events automatically by the date and time. This is a more advanced topic that is
discussed in the next section of this manual.
5.5.1 Setting the Calendar
Set the calendar in the RFC-1 by entering the command 70. Use leading zeros for values less than 10.
1. Enter the command to set the calendar: 70
2. The RFC-1 will read the current settings from memory.
3. At the prompt, press the # key to set the date: #
4. At the prompt, enter a two-digit month:
n
5. At the prompt, enter a two-digit date:
n
6. At the prompt, enter a four-digit year:
n
7. The RFC-1 responds with “OK”, the procedure is complete
5.5.2 Setting the Clock
Set the clock in the RFC-1 by entering the command 71. Use a 24-hour clock and use leading zeros for values less
than 10. The seconds reset to zero when the last digit is entered.
1. Enter the command to set the clock: 71
2. The RFC-1 will read the current settings from memory.
3. At the prompt, press the # key to set the date: #
4. At the prompt, enter a two-digit hour:
n
5. At the prompt, enter a two-digit minute:
n
6. The RFC-1 responds with “OK”, the procedure is complete
