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.
Dip Switch 1 enables the auto answer feature. When in the ON position, the C-250 will answer an incoming call after
the number of rings programmed into location #45. If position #45 is cleared, or contains 00, the C-250 will not
answer the line. If this feature is enabled, there cannot be anything else on the phone line that could answer the call
before the C-250 such as an answering machine. If security is an issue, it is best to not allow remote programming
and leave DIP Switch 1 in the OFF position. The factory setting is OFF.
1. DIP Switch 1
L. “No CO” Mode (Q0,Q1)
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 “
Q1” when in programming. To cancel the “No CO” mode,
enter “Q0”.
M. “Door Bell” mode (Q2,Q3)
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 “
Q3”. To cancel the “Door Bell” mode, enter “Q2”.
N. Ring Pattern (Q4,Q5)
In the factory setting (Q4), 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 “
Q5”. 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 “
Q4”.
O. Remote Door Strike Actuation (Q6)
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 “Q6”. After a short pause, the door strike relay will actuate for the programmed amount of time in the Door Strike
Activation Time position #40.
