Specifications

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 high-
er 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 on next page).

R. Recording Messages
Recording of the voice messages may be done either locally or remotely. Once programming has been entered, touch
tones are used to start and stop the recording process. To start a recording: enter
, followed by the number of the
input. The K-2000-DVA gives a single beep to indicate that it is recording and then starts the recording process. Speak
into the handset of the telephone or provide line level audio to the REC IN jack to record the message. The K-2000-
DVA has a maximum message time for each input of one minute. When finished recording the message, enter any
touch tone to stop the recording process. At this point the K-2000-DVA automatically plays back the message just
recorded. If the recording process goes over one minute the K-2000-DVA stops the recording and starts playing back
the message. To clear a single message: enter
, followed by the number of the input and then immediately press any
Touch Tone to stop the recording process.
S. Playing Back Messages
When in programming, enter ,0 followed by the number of the input to play back the message recorded for that input.
If no message has been recorded, nothing will be heard.
T. Return to Default
IMPORTANT: Executing the following programming erases all phone numbers and messages and returns the
K-2000-DVA to default settings.
To erase all messages and phone numbers and to return the K-2000-DVA to its original default settings enter ### while
in programming.
Q. Hookswitch Flash Before Dialing
In the majority of alarm dialing applications, the K-2000-DVA simply goes off hook on the phone line or PBX extension,
pauses one second, then begins dialing the programmed phone (or pager) number. In a few alarm dialing applica-
tions, the K-2000-DVA must go off hook on the phone line or PBX extension and provide a 500 millisecond hookswitch
flash before dialing the programmed phone number. This feature can be enabled or disabled on a global basis (applies
to all inputs and all dial numbers). To enable the hookswitch flash before dialing enter ##6. To disable the hookswitch
flash before dialing enter ##5 (default). When hookswitch flash before dialing is enabled, the K-2000-DVA goes off
hook, waits 2 seconds, provides the 500 millisecond hookswitch flash, waits one second then dials the programmed
phone number.
