When connected directly to a single telephone or an un-
used C.O. port on a PBX or KSU system, use the PHONE
OUT terminals only. The 1812 must be programmed for
INTERCOM mode using this configuration.
When the 1812 is programmed for intercom mode, it
provides the constant source of DC voltage necessary for
communication. The intercom mode also disconnects the
phone in terminals (1 and 2) since they are not used.
Be sure that the 1812 is programmed in the intercom mode
when connecting the unit as shown above.
This device is powered by a 16.5 VAC
transformer. DO NOT power this device with a
24 VAC transformer or power source.
