The K-202-DVA constantly monitors both alarm inputs to see if either of them leaves their normal state (N/O becomes closed

or N/C becomes open) for more than 80 ms. In the event of two simultaneous closures, Input 1 has 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-202-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-202-DVA dials the first phone number associated with that input. When

dialing is completed, the K-202-DVA looks to see if call progress detection is enabled. If it is, the K-202-DVA counts ring-

backs while looking for an off-hook. If the call is not answered before the programmed ringback limit is reached, the K-202-

DVA will hang up and dial the next number in the list. If the called party goes off-hook, the K-202-DVA starts playing the alarm

message associated with that input. If call progress detection is not enabled, the K-202-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. Note: If the phone number is a pager number, the K-202-DVA does not play the alarm message, but instead pauses

two seconds and hangs up. When the called party answers there are 4 options available:

Touch Tone

Result

Stops the currect message if playing and plays message 1 if Input 1 has an alarm that has not been reset, fol-

lowed by Message 2 if Input 2 has an alarm that has not been reset. If neither input has an alarm that has not

been reset, the K-202-DVA gives three beeps.

Stops the current message if playing and plays the other message if the other input has an alarm that has not

been reset. If the other input does not have an alarm that has not been reset the K-202-DVA gives three beeps.

Stops the current message if playing, hangs up and continues dialing if applicable.

Stops the current message if playing and resets the alarmed input.

S. Playing Back Messages

When in programming, enter Q0 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-202-DVA to default settings.

To erase all messages and phone numbers and to return the K-202-DVA to its original default settings enter ### while

in programming.

Once the message repeat count has been met without a response, the K-202-DVA will give a single beep to indicate that it

has delivered its messages and is about to hang up. The K-202-DVA will then pause for five seconds to allow the called

party a final opportunity to exercise one of the above options.

If the K-202-DVA delivers its message and the called party does not reset the alarmed input the K-202-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-202-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-202-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-202-DVA starts looking at the input again right away. If the closure is still in effect,

the K-202-DVA waits for it to go away. If the closure is no longer in effect but a short time later it returns, the K-202-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-202-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-202-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-202-DVA. After it answers and provides its single beep as a prompt, enter Q

followed by the six digit Access Code. The K-202-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-202-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-202-DVA. For more information, see “Related Products” on the following page and retrieve
