Operation - Viking K-2000-DVA Product Manual

A. Alarm Dialer Mode
The K-2000-DVA constantly monitors all eight alarm inputs to see if any of them leaves their normal state (N/O becomes closed or
N/C becomes open) for more than 80 ms. In the event of multiple closures, lower numbered inputs have higher priority. What
happens after a closure is detected depends on the Qualifier Timer setting for the input. If the Qualifier Timer is set to zero, the
event qualifies as an alarm immediately and the input enters the alarm state. Otherwise the K-2000-DVA counts down from the
Qualifier Timer value to zero, all the while watching to see that the closure remains in effect. If the Qualifier Timer reaches zero and
the closure has not gone away the event qualifies as an alarm and the input enters the alarm state.
When an input has entered the alarm state, the K-2000-DVA dials the first phone number associated with that input.
Note 1: If the phone number is a pager number, the K-2000-DVA does not continue, instead it immediately hangs up after dialing
the phone number (goes on to the next number if there is one).
Note 2: If Hookswitch Flash Before Dialing is enabled (##6), the K-2000-DVA grabs the phone line and generates a 500 ms
hookswitch flash before dialing the phone number.
When dialing is completed, the K-2000-DVA looks to see if call progress detection is enabled. If it is, the K-2000-DVA counts
ringbacks while looking for an off-hook. If the call is not answered before the programmed ringback limit is reached, the K-2000-
DVA will hang up and dial the next number in the list. If the called party goes off-hook, the K-2000-DVA starts playing the alarm
message associated with that input. If call progress detection is not enabled, the K-2000-DVA simply waits until the forced play
timer has expired and then starts playing the alarm message regardless of whether the called party has answered or not. When the
called party answers there are 4 options available (shown below).
Touch Tone Result
Stops the current message and plays all messages associated with all alarmed inputs in order,
1
from first to last.
2 Stops the current message and plays the next message, if applicable.
3 Stops the current message, hangs up and continues dialing if applicable.
9 Stops the current message and resets the alarmed input.
These commands must be entered during the alarm message. Once the message repeat count has been met without a response,
the K-2000-DVA will give a single beep to indicate that it has delivered its messages and is about to hang up.
If the K-2000-DVA delivers its message and the called party did not reset the alarmed input the K-2000-DVA hangs up and dials the
next number on the list for that input. If all numbers have been dialed and the alarm is still not reset the K-2000-DVA increments the
lap counter for that input and starts the dialing process over again. This will continue until the lap counter has been met. At this
point the K-2000-DVA marks the input as an alarmed input and returns the input to its rest state.
If an alarm input is reset, the manner in which the input resumes normal operation is determined by the Resume Timer. If the Resume
Timer is set to zero, the K-2000-DVA starts looking at the input again right away. If the closure is still in effect, the K-2000-DVA
waits for it to go away. If the closure is no longer in effect but a short time later it returns, the K-2000-DVA will start the alarm dialing
procedure all over again for that input. However, if the Resume Timer is set to a non-zero value, the K-2000-DVA counts down from
that value to zero and then examines the input to see if the closure is still in effect. If it is, the alarm dialing procedure starts again.
If not, the input goes back to the rest state.
It is also possible to remotely access the K-2000-DVA to poll it for any alarms that might not have been reset. This is done by calling
the phone line connected to the K-2000-DVA. After it answers and provides its single beep as a prompt, enter Q followed by the six
digit Access Code. The K-2000-DVA gives two beeps and the 4 above options become available.
Note that if a Q is entered while connected to the call the K-2000-DVA will exit its current mode and if no touch tones are entered
within 20 seconds, it will hang up and proceed. This 20 second wait is important, so that an RC-2A or RC-3 can be used in conjunction
with the K-2000-DVA. For more information, see DOD# 830.
B. Store Caster Mode
In the Store Caster Mode the K-2000-DVA monitors the inputs to see if any of them leaves their normal state (N/O becomes closed
or N/C becomes open) for more than 80 ms. When this occurs, the K-2000-DVA plays the message associated with the input, and
repeats the message until the repeat count is met.
In the Store Caster mode, if an input never returns to the normal state (N/O with a continuous closure or N/C with a continuous
open), the K-2000-DVA will continue to repeat the message for that input until the input finally does return to the normal state (even
with a message repeat of only one). In this mode, the 600-ohm audio output can be tied to a paging system for promotional or
assistance announcements
If there is a closure on another input while the message from the first input is playing, this information is stored, and the message
associated with the second input is played as soon as the first input is done. It is possible for all eight inputs to be activated, and if
this is the case, the K-2000-DVA will play the messages in order of priority, with lower numbered inputs having higher priority.
