The Status LED gives an indication of the alarm status of the 

K-202-DVA

. If neither of the inputs are in the alarm state or

marked as the result of previous dialing that did not result in a remote reset, the Status LED remains lit steady. If Input 1
enters the alarm state, the Status LED gives a quick flash every second until reset. If Input 2 enters the alarm state, the
Status LED gives a quick double flash every second. If both inputs are in the alarm state, the Status LED alternates
between a single flash and a double flash every second. The Status LED flashes in the same way when either or both of
the inputs are marked. To reset the 

K-202-DVA

, either provide a closure between the reset terminal and chassis ground

(not earth ground) or call the unit, and when it answers, enter 

Q 

plus the access code, then 1 and 9 while the message is

playing ( see B. Remote Access Polling on Page 7).

F  Status LED Alarm Indication

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  If the closure is no longer in effect but a short time later it returns, the 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.  

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 

DOD# 878

.

The PA mode is useful in applications where the 

K-202-DVA

is providing emergency or informational messages over a

paging system, activated from an alarm system, panic buttons or doorbell buttons.  When an input is activated, the 

K-202-

DVA

dials the access code or extension number for the PA  system and listens for a busy signal.  If it does not hear a busy

signal the forced play timer expires and the recorded message plays for the programmed number of repeats.  Unlike the
alarm dialing mode, this mode does not produce a beep after the message has played, so beeps are not sent out over the
speakers.  If the 

K-202-DVA

does hear a busy signal it hangs up, waits two seconds and then dials the access code for

the PA system again, provided that the lap counter has not been reached yet.  The 

K-202-DVA

will keep repeating this

process until a busy signal is not heard or the lap counter reaches its programmed value.  Once the 

K-202-DVA

plays the

message or the lap counter expires it returns to idle and waits for another input trigger.  The lap counter in this mode is
actually a counter for the maximum number of times the 

K-202-DVA

will attempt to call a busy paging port before it gives

up.  When playing emergency messages over the paging system, the lap counter should be set fairly high to ensure the
emergency message eventually plays, especially on systems with heavy paging traffic.     

C.  PA (Public Address) Mode

B.  Remote Access Polling

At the end of the standard alarm dialing procedure when the lap counter has been met the  

K-202-DVA

resets the input

and marks it to keep track of the fact that there was an alarm that was not reset by the user.  From this point on, while it is
possible to call in to the 

K-202-DVA

and poll it to discover that there was an alarm, the 

K-202-DVA

does not initiate any

more dialing.   

This alarm situation is handled differently when the auto-resume feature is enabled.  The 

K-202-DVA

resets and marks

the input, but it also starts the resume timer, the value of which is set in programming (see 

Programming

section 

I

).  While

the resume time is running, the unit will not call its programmed numbers, but it will play the alarm message of the marked
input if it is polled, and the user can dial a touch tone 9 to return the input to its rest state.  If the resume timer elapses
without a call from the user, the 

K-202-DVA

clears the lap counter and starts the alarm dialing sequence again from the

beginning.  If the lap counter is reached again, the unit ceases dialing and the resume timer is started again. This will
continue until one of the called numbers answers and resets the input by dialing a touch tone 9 or until a user calls in, polls
the unit by dialing a touch tone 1, and resets the alarmed input by dialing a touch  tone 9.  See 

Operation

section 

B

for a

description of the polling procedure.

D.  Auto Resume Mode

A momentary switch can be connected between the Reset Terminal and chassis ground (not earth ground) to provide a
local reset to both inputs. See the Installation diagram on page 3 to see how to hook this up. A closure resets either or
both of the inputs if they are in alarm state, and will also clear either or both of the inputs if they are marked. Note that the
inputs may alarm again if the resume timer is set to zero and the condition that caused the alarm has not been corrected.

The K-202-DVA can be called from a remote location to check on possible alarm activity. When the phone line it is
connected to is called, it answers and gives a single beep as a prompt. Enter 

Q 

followed by the 6 digit access code, the K-

202-DVA gives 2 beeps, and the for options in Figure 1 on page 6 become available. When finished, dial 3 to disconnect (3 beeps
are heard) or just hang up. Note that the K-202-DVA will give 3 beeps and hang up if 20 seconds go by without a touch tone entry.
