call, wait 70 seconds for a call back acknowledgment, and then place a call to the next
telephone number in the list. If an acknowledgment is not received from the next call
after another 70 second wait, a 3rd call will be placed, and so on. The unit will continue
to call repeatedly from the user’s programmed list of telephone numbers until it receives
an acknowledgment or the fault condition is removed.
If the system is acknowledged during the call, it will not place any further calls for a time
programmed as the Intercall Delay. If a new fault condition occurs during that period,
the Intercall Delay will abort and calls will begin again. If the entire Intercall Delay
expires and the fault conditions still persist, the system will again begin to place
telephone calls.
To Acknowledge a Call From the System
Acknowledgment may be accomplished by depressing the * key on the called telephone
between message repeats during the alarm call. The * key must be depressed for at
least 2 full seconds but not longer than 5 seconds. The system will verify that the
acknowledgment has been accepted by saying the recorded voice message for proper
alarm acknowledgement [Voice message 7].
If acknowledgment must be returned from a telephone without tone capability, the
system may be acknowledged by placing an immediate call back to the system, within
60 seconds after it has completed its call. Again, the system will verify that the
acknowledgment has been accepted by saying, [sign off message, in location number 7,
as programmed above, will be recited].
D. TEST AND ADVANCED KEYSTROKE SEQUENCES
