VAD-2 Installation and Operation Manual
OPERATION
OPERATION
Voice Dialing
When one of the two dry contact inputs configured for either normally open or nor-
mally closed operation have been triggered for at least 4 seconds and/or a silence
sense, the VAD-2 will begin dialing the first telephone number programmed for that
input. Five seconds after dialing a telephone number, the VAD-2 will begin repeat-
ing the recorded message associated with the tripped input. The message will be
repeated for the “repeat counter” setup for that input. The VAD-2 is a voice alarm
dialer that automatically reports changes detected on any one of its two digital inputs
and/or silence sensor to a remote telephone, pager and/or * logging computer. After
speaking a greeting message that may identify the source of the call, the VAD-2 then
speaks a unique message for each input change. Each message comes factory pro-
grammed, but may easily be re-recorded locally or remotely with your own cus-
tomized messages.
EXAMPLE: If you want a pager to be called, when call number 1 on the dial out
list for input 2:
Then program 51 into the input 2 - dial list. The pager will be called and then the
first number will be called on the dial list. The alarm message will be played the
number of times that is programmed into the “repeat” memory. If there is no
acknowledgment (“*”) the VAD-2 will go on to the next number and so on until all
numbers stored in that Input’s dial list have been called. This process will then be
repeated for the number of times stored in the “lap” memory. The lap memory is
global and is the same for both inputs while the repeat memory is programmable by
input.
After reporting, the VAD-2 is ready to receive commands after the security code is
entered through your telephone keypad. Functions include telling the VAD-2 to
report on the input state of any of the two digital inputs, commanding the VAD-2 to
pulse any one of its two SPDT relays for 1 second and/or turning any one of the
relays on or off. When a relay command is given, the VAD-2 will emit a high or
low tone corresponding to the condition of the relay(s).
To acknowledge an input alarm, you must enter the “*” key when called. You will
hear an acknowledgement beep. Once an input has been acknowledged, a new alarm
will be generated if that input goes back to its normal state for 5 seconds and returns
to its alarm state. No new alarm will be generated if it stays in its alarm state. With
multiple alarms, input 1 is resolved first, then two, then the silence sensor.
In addition to initiating a call out when any input changes, the VAD-2 monitors its
telephone line to receive a call-in from a remote location. When a call is received,
the VAD-2 speaks a greeting message, and is then ready to receive the security code
and then execute commands to report on inputs, or changes to the two relays.
