Program a Telemetry Alarm Block

The RFC-1/B can respond to telemetry conditions using alarms. There are eight alarms in the RFC-1/B.

Some alarms are not valid during certain hours of the day. For example, tower lights are typically not on during the day so an alarm that monitors tower lights can be blocked so that it does not trip during daylight hours.

Alarm Block

The alarm block consists of the alarm to block, a start time and an end time.

Alarm blocks work across midnight
Alarm blocks begin and end on the hour–there is not a minute setting

Keep in mind that the alarm is what is being blocked, not the telemetry channel. If you want to block a tower light alarm and the tower lights are on channel 07, you must know what alarm monitors channel 07 to properly setup the block.

Shared Memory

The RFC-1/B does not have dedicated memory for alarm blocks. Instead, alarm blocks must share space with date/time triggers. The system stores stores between 48 and 80 date/time triggers.

The system knows the difference between alarm blocks and date/time triggers so you do not have to worry about keeping them listed separately. However, the system may be easier to maintain if you keep them in separate groups.

Instructions

Use the selections below to block an alarm. All items must be completed.

The values and adresses will be calculated and displayed. Click the "Show Instructions" button to display step-by-step programming instructions.

Telemetry Alarm

This is the alarm that will be blocked.

Alarm: select an alarm from the list

Start Hour

This sets the starting time for the alarm block.

Start: select start hour

Stop Hour

This sets the ending time for the alarm block.

Stop: select stop hour

Date/Time Trigger

This determines where the alarm block is stored in memory.

Select an unused date/time trigger. Selecting a date/time trigger that is in use will not harm the system but will overwrite the existing information and change the behavior of the system.

All systems store at least 48 date/time triggers. The factory settings allow 72 date/time triggers to be used.

If no timed events are in use, start with number 1 and use the next item for each new event. No timed events are programmed at the factory.

Trigger: select a date/time trigger from the list
