2.2 System
Parameter
Programming
2.2.1 Phone / Intercom Mode
Default setting is 1 (Phone Mode).
The 1812 is normally connected in series with a resident’s incoming phone line, which supplies a
constant source of DC voltage. When the 1812 is connected in this manner, program the unit for
PHONE mode.
If the 1812 is to be connected to an open C.O. (Central Office) port on a key type telephone system,
or if the 1812 is connected directly to a telephone without a C.O. line, program the unit for
INTERCOM mode. When programmed in intercom mode, the 1812 will supply the constant DC
voltage necessary for operation and will disconnect the PH-IN terminals from the circuit since these
are not used in intercom mode.
If the 1812 is programmed for the intercom mode, the call forwarding and preprogrammed dial-out
phone number features will not work.
1. Press * 0 6 and enter the MASTER CODE.
[ * 0 6 _ _ _ _ (beep)]

OR

2.2.2 Single or Multiple Systems

one 1812 is connected to the phone line.

2.2.3 System Attention Number
Default setting is 7.
The system attention number is the number that the 1812 responds to when called from the
residence. If more than one 1812 is sharing the phone line, be sure the attention number to each unit
is programmed with a unique attention number.
1. Press * 6 2 and then enter the MASTER CODE.
[ * 6 2 _ _ _ _ (beep)]

2.2.4 Single or Double Ring

Setting this for a double ring provides a unique ring so that a call from the 1812 is easily identified, or
the ring can be set to the standard single long ring.
1. Press * 6 3 and then enter the MASTER CODE.
[ * 6 3 _ _ _ _ (beep)]
2. Press 1 * for a double ring
