The PA mode allows the
K-202-DVA
to play recorded messages over a paging system. For a description of how
the mode functions, see
Operation
section
B
. This feature is enabled or disabled on a global basis (applies to
both inputs and all dial numbers). When in programming, enter
##6
to enable the PA mode. When the PA mode
is enabled, the forced play timer should be set to 10 seconds (see
Programming
section
N
) and the lap counter
should be set to a value higher than 1 (see
Programming
section
G
). To disable the PA mode enter
##5
(default).
All options for the inputs are still programmable (normally open or normally closed, momentary or continuous,
qualifier timer, etc). Note that the PA mode should not be enabled if the Auto-Resume mode has been enabled
because the
K-202-DVA
will not function properly with both modes enabled.
S. PA (Public Address) Mode
Operation
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 90 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 ringbacks while looking for the called number to answer. 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 answers, 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, as shown in Figure 1 below.
A. Alarm Dialer Mode
Touch Tone Result
1
Stops the current message if playing and plays message 1 if Input 1 has an alarm that has not been reset,
followed 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.
2
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.
3
Stops the current message if playing, hangs up and continues dialing if applicable.
9
Stops the current message if playing and resets the alarmed input.
6
In the majority of alarm dialing applications, the
K-202-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 applications, the
K-202-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 both inputs and all dial numbers). To enable the hookswitch flash before
dialing enter
##4
. To disable the hookswitch flash before dialing enter
##3
(default). When hookswitch flash
before dialing is enabled, the
K-202-DVA
goes off hook, waits 2 seconds, provides the 500 millisecond hookswitch
flash, waits one second then dials the programmed phone number.
R. Hookswitch Flash Before Dialing
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.
U. Return to Default
Figure 1
See
Operation
section
D
for a functional description of this mode. The Auto-Resume mode is disabled by default
but can be enabled by entering ##9 in programming. In addition, a value for the resume timer should be set so
the unit knows how long to wait before repeating the alarm dialing procedure (see
Programming
section
I
). To
disable the mode, enter
##8
. The Auto-Resume mode should not be enabled if the PA mode has been enabled
because the
K-202-DVA
will not function properly with both modes enabled.
T. Auto Resume Mode
To select normal dialing speed (100 ms) enter
##1
. To select fast dialing speed (50 ms) enter
##2
