RFC-1 Programming Examples page 7.11
7.10 Tower Light Alarm
In this example we will program an alarm to monitor a telemetry channel that has a sample from a tower lighting
system. We will use channel 06 as our telemetry input. It is programmed to read “100.0 percent” when all lights are
operating properly—this is a direct reading from the telemetry sample programmed with the unit word “percent”.
Alarm C will be programmed to monitor channel 06 for 10 percent over and 10 percent under. Adjust the alarm limits
to suit your system.
1. Enter the advanced programming mode: 80
2. Enter the advanced programming security code: 4150
3. Enter the starting address from the address table for Alarm C: 0876
4. Enter the first digit of the telemetry channel to be monitored: 0
5. Press the # key to write this value and increment to the next address in memory
6. Enter the second digit of the telemetry channel to be monitored: 6
7. Press the # key to write this value and increment to the next address in memory
8. From Section 6, enter the number of the trigger rule: 5
9. Press the # key to enter this value and increment to the next address in memory
10. Enter the number of the Action Sequence that should be triggered: 1
11. Press the # key to enter this value and increment to the next address in memory
12. Enter the first digit of the upper limit: 1
13. Press the # key to write this value and increment to the next address in memory
14. Enter the second digit of the upper limit: 1
15. Press the # key to write this value and increment to the next address in memory
16. Enter the third digit of the upper limit: 0
17. Press the # key to write this value and increment to the next address in memory
18. Enter the fourth digit of the upper limit: 0
19. Press the # key to write this value and increment to the next address in memory
20. Enter the first digit of the lower limit: 0
21. Press the # key to write this value and increment to the next address in memory
22. Enter the second digit of the lower limit: 9
23. Press the # key to write this value and increment to the next address in memory
24. Enter the third digit of the lower limit: 0
25. Press the # key to write this value and increment to the next address in memory
26. Enter the fourth digit of the lower limit: 0
27. Press the # key to write this value and increment to the next address in memory
28. Press the ❊ key to exit the programming mode
Alarms A-H in the RFC-1 can be reprogrammed using the basic programming commands 90-97 respectively. Only
the channel number and limits can be changed with the basic programming commands. Changing the trigger rule
and action sequence require using the advanced programming mode. This example could also have been
programmed with the command 92 since both the trigger rule and action sequence use the default values.
In the factory default settings, all alarms trigger action sequence 9, which is programmed to call all available
telephone numbers.
There is a master on/off switch for the telemetry alarm system. Adjust this setting with the command 82. A value of 0
disables all telemetry alarms and the value 1 enables the telemetry alarms.
In the next example we will program an alarm block that disables the tower light alarm during daylight hours.
