F. Maximum Call Time (Memory Location #42)
The Maximum Call Time can be used to cut off a call that has rolled over to an outside number. The timer starts as soon
as the
C-250
is done dialing each number. If the call lasts longer than the time programmed, the phone line will be
dropped and a busy signal will be sent to the entry phone. This is useful if a standard telephone is being used for an
entry phone and the handset is accidentally left off hook. This one digit number can range from 1 to 9 minutes or enter
0 for 30 seconds. To disable this feature enter #42 without any preceding digits. The factory setting is 3 minutes.
G. Maximum Ring Time (Memory Location #43)
After the
C-250
dials an outside number, it listens to the phone line for busy, ringing, or someone answering at the other
end. The Maximum Ring Time is used to limit this process in the event that the
C-250
cannot determine if the call has
been answered. If the
C-250
cannot determine that the call has been answered within the Maximum Ring Time, the line
will be disconnected and the
C-250
will go onto the next speed dial number. This two digit number can range from 01
to 59 seconds and can be disabled by entering #43 without any preceding digits. As a general rule, allow 6 seconds for
each ring you desire at the distant phone. The factory setting is 30 seconds or about 5 rings.
H. Security Code (Memory Location #47)
The security code must be 6 digits long and cannot contain a “
Q
” or “#”. The factory default code is “845464” and can
be changed in programming by entering 6 digits followed by “#47”.
D. Door Strike Activation Time (Memory Location #40)
The value stored in the Door Strike Activation Time is the amount of time the door strike relay will be energized after a
correct touch tone command is entered or the trigger input is activated. This two digit number can range from 01 to 99
seconds, or enter 00 for 0.5 seconds. The factory setting is 5 seconds.
E. Door Strike Command (Memory Location #41)
The one or two digit code stored in the Door Strike Command is the touch tone command that the person being called
must enter on their touch tone phone in order to actuate the door strike. The code can contain the numbers 1 to 9, 0,
Q
, # or any two digit combinations. To disable this feature enter #41 without any preceding digits. The code must be
entered while the house phone or the remote phone is connected to the door phone.
The
C-250
determines which direction the touch tone is coming from and only responds to touch tones from the called
phone. Because of this, single digit codes must be a minimum of 100 msec in duration. Some cell phones can only pro-
duce fast touch tones (< 100 msec). If using one of these phones, program a two digit Door Strike Command. When
two digits are programmed, the entry phone will be dropped after the first digit, so the
C-250
can be sure the second
digit is coming from the called phone. With a two digit code, the minimum duration of the tones can be as low as
50msec. The factory setting is 6.
I. Ring House Phone Count (Memory Location #44)
When the door phone comes off hook, the
C-250
will start ringing the house phone. The number of times the house
phone will ring is stored in location #44. This value can range from 1 to 9, if blank or 0 is entered, the
C-250
will skip
ringing the house phone and immediately start calling the programmed phone numbers. This feature is useful when the
user is not at home and they want the fastest connect time to their cell phone. There is also an operational command
of
QQQ
(see
Operation
section
B
) and a trigger input (see section
N
, DIP switch 2) that can be used for immediate call
forwarding. The factory setting is 4.
J. Incoming Ring Count (Memory Location #45)
The 2 digit number in this location determines how many times a call coming in from the phone line will ring the house
phones before the
C-250
answers the call. This number can range from 01 to 99, if blank or 00, the Auto Answer fea-
ture of the
C-250
will be disabled. The factory setting is 10.
K. Ignore Touch Tones for Programming Entry Phone (##1)
This feature is useful if you have a entry phone that requires touch tone programming and can answer a ringing line
after 1 ring. All Viking Handsfree Entry Phones have this capability. After entering the programming mode, if ##1 is
entered, the
C-250
will send a ring signal to the entry phone port. If the device on that port answers the line, the
C-250
will connect it to the calling device (local or remote). If the entry phone does not answer, 3 beeps will be heard and the
C-250
will stay in the programming mode. Once connected to the door phone, the
C-250
no longer reacts to touch tones
(except to reset the 20 second programming timer in the remote programming mode). In the remote programming
mode, if the 20 second programming timer elapses, the
C-250
will hang up. In any of the other programming modes,
the timer is disabled and the
C-250
only watches for the door phone to hang up.
