R. DIP Switch Programming
P. Exit Programming (##7)
When this command is entered, the
C-250
will leave the programming mode and go back to normal operation. This
command is useful in remote, auto answered programming. It causes the
C-250
to drop the phone line immediately
rather than waiting for the 20 second time out.
Q. Reset All Programming to Default (###)
This command resets all programming parameters to their factory settings and clears out all programmable phone num-
bers.

L. “No CO” Mode (
Q
0,
Q
1)
When enabled, this mode allows the
C-250
to be used in installations that do not have an incoming phone line. In this
mode, the house phone is connected directly to the internal artificial line. When the house phone comes off hook, the
door phone will start to ring. If the door phone has auto answer, the person in the house can monitor any outside activ-
ity. Door phone calls are handled the same as in the normal mode except it will not roll over to the phone line if there
is no answer at the house phone. To enable this mode, enter “
Q
1
” when in programming. To cancel the “No CO” mode,
enter “
Q
0
”.
M. “Door Bell” mode (
Q
2,
Q
3)
If the door strike relay is not being used, it can be configured to operate a door bell. When in this mode, the door strike
relay will actuate whenever the door phone goes off hook. Connect the door bell or chime (and power supply) to the
normally open door strike contacts. The door strike relay will energize for a fixed time period of 1 second. To enable this
mode, go into programming and enter “
Q
3
”. To cancel the “Door Bell” mode, enter “
Q
2
”.
N. Ring Pattern (
Q
4,
Q
5)
In the factory setting (
Q
4
), the
C-250
will ring the house phones with a double burst pattern when the door phone goes
off hook. This is done so that the person in the house can tell the difference between a visitor at the front door and a
regular phone call. In a few instances the double burst pattern may not be detected by some cordless phones. If this is
the case, go into programming and enter “
Q
5
”. This will cause the
C-250
to send a single burst pattern when the door
phone goes off hook. To go back to the double burst pattern, go into programming and enter “
Q
4”.
O. Remote Door Strike Actuation (
Q
6)
The door strike relay on the
C-250
can be actuated remotely without the
C-250
initiating the call. To do this, dip switch
1 must be in the ON position and a value must be entered in the Incoming Ring Count location
#45
. From the remote
location, call into the
C-250
. After it answers, enter a “
Q
” followed by the 6 digit security code. Wait for the 2 beeps and
enter “
Q
6
”. After a short pause, the door strike relay will actuate for the programmed amount of time in the Door Strike
Activation Time position
#40
.
