RFC-1 Advanced Operation page 6.19
6.5.5 Alarm Calls
The RFC-1 can place telephone calls as a step in an action sequence. The message delivered depends on the
condition that triggers the action sequence. The message typically consists of the site identification phrase followed
by an indication of the condition that triggered the call such as a telemetry alarm or power failure. The message
repeats for a pre-determined length of time.
Select an instruction from the table below and program the corresponding V1 and V2 in the action sequence to
generate telephone calls as part of an action sequence.
Telephone call instructions
Call all telephone numbers in rotation: A, B, C, D, E, F, A, B, C, …
Call all telephone numbers in weighted rotation: A, B, A, C, A, D, A, E, A, F, A, B, …
Call telephone number A the programmed number of times
Call telephone number B the programmed number of times
Call telephone number C the programmed number of times
Call telephone number D the programmed number of times
Call telephone number E the programmed number of times
Call telephone number F the programmed number of times
The number of calls placed to a given telephone number is determined by the call attempts setting. Each telephone
number has its own call attempts setting. The setting is programming in the address following the telephone number
digits. See telephone number programming for more information.
When the RFC-1 places a telephone call, the call lasts for a pre-set amount of time, the call duration. The outgoing
message is repeated for the duration of the call. Select a call duration setting from the table below and program the
corresponding V1 at address 1003. Call duration applies to voice mode calls only.
30 seconds (default setting)
The RFC-1 pauses between outgoing calls when multiple telephone calls are made, the call pause duration. This
provides an opening for an operator to contact the system. Select a call pause duration from the table below and
program the corresponding V1 at address 1004.
