DIP Switch 3 in the ON position is used to gain access to the programming mode without needing a security code. When the

house phone goes off hook, two beeps will be heard signaling that the C-250 is ready for programming commands. If a call

comes in and the auto answer feature is also enabled (DIP Switch 1 ON), the C-250 will answer the call on the first ring and send

2 beeps. When in the off position, the security code in position #47 has to be used in order to enter programming. This switch

needs to be off for normal operation. The factory setting is OFF.

A. Visitors

When the entry phone goes off hook, the house phones will ring with a distinctive double ring cadence to identify it is

a entry phone call (programmable to a single ring cadence). The number entered into programming position #44 deter-

mines how many times the house phone will ring from an entry phone call before the call is forwarded using the auto

dialing numbers. If no numbers are programmed, the C-250 will send a CPC signal to automatically hang up the entry

phone. All Viking hands free phones are able to detect the CPC signal and hang up. If the C-250 senses that the entry

phone has not dropped off, it will send a busy signal. If auto dial numbers are programmed, it will dial the first one and

watch for a busy or no answer for the duration of the Maximum Ring time. If this time elapses and the C-250 has not

determined the call has been answered, it assumes that the call was not answered and goes on to the next speed dial

number. If all numbers are called without an answer, the C-250 will send a CPC signal to hang up the entry phone. The

Maximum Call Time is started as soon as the C-250 is done dialing each number. If this timer elapses, that call is ter-

minated and no further numbers are dialed.

B. Immediate Call Forward

The entire sequence of the house phone ringing when the entry phone goes off hook can be skipped. This is useful if

the user will not be at home and wants the C-250 to skip ringing the house phone and immediately forward all entry

calls to the programmed phone numbers. There are several ways to do this. The first is to clear the house phone ring

count or set it to 0 in programming position #44. This can only be done in the programming mode, but can be done

locally or remotely if auto answer (DIP Switch 1) is on. The second way is to go off hook with any house phone and

enter “

QQQ”. This places the C-250 in the Immediate Call Forward mode. With this mode enabled, each time the house

phone goes off hook, a single beep will be heard in order to let the user know that this mode is on. To cancel the

Immediate Call Forward mode, pick up the house phone and enter “###”. Two beeps will be heard letting the user know

the Immediate Call Forward mode has been cancelled. These immediate call forward commands must be entered with-

in 5 seconds of off hook. The third and final way is to provide a contact closure across the trigger input (DIP switch 2

must be ON).

Note: “

QQQ

” activation of this feature can be disabled if users are accidentally entering

QQQ

while trying to retrieve

voice messages, unintentionally activating immediate call forwarding. In programming, enter 1#51 to disable the fea-

ture. Immediate call forwarding can still be activated in one of the remaining two ways described in the above para-

graph. Enter 0#51 in programming re-enables

QQQ

activation of immediate call forwarding.

C. Monitoring or Receiving Door Phone Calls

If the tenant wants to monitor the entry phone, they can pick up any phone in the house and hook flash within 5 sec-

onds. This will cause the C-250 to ring the entry phone up to 5 times. Hook flashes after the 5 second time out will be

passed along to the CO line. This is useful for using standard CO call waiting features. If the tenant is on an outside

call, and the entry phone comes off hook, a call waiting tone will be heard every 12 seconds. The tenant can then hook

flash to put the CO call on hold and connect to the entry phone. When the conversation with the person at the door is

done, the tenant can return to the original caller with another hook flash. If using a 2 digit door strike code, the entry

phone will be dropped after the first digit.

DIP Switch 2 determines the operating mode of the Trigger Input. When DIP Switch 2 is OFF, a momentary closure connected

to the trigger input will cause the Door Strike relay to actuate for the programmed amount of time in location #40. If DIP Switch

2 is in the ON position, the Trigger input now controls whether or not the house phone will ring when the door phone goes off

hook. If the trigger input is open, the house phone will ring for the number of times programmed in location #44. If the trigger

input is closed, the C-250 will skip ringing the house phone and go right to calling the preprogrammed phone numbers. This

Trigger Input mode is useful if you want to control the operation of the C-250 by some other piece of equipment such as a phone

system placed in the night mode, a clock controlled relay or a toggle switch. The factory setting is OFF.
