DoorKing 1816 Intercom System-Multi - Manual (Page 14)

1.3 Cabinet, Relay and Component Identification
For identification purposes, the Main Control Cabinet is defined as that part of the 1816 system that
houses the main processor control board, and at least one, but not more than five, relay boards.
Auxiliary Cabinets are defined as that part of the 1816 system that houses one decoder board, and at
least one, but not more than eight, relay boards. Each cabinet is identified with a label and the
system relays that it houses. There can only be one Main Control Cabinet per 1816 system,
however, there can be several Auxiliary Cabinets per system. Auxiliary cabinets start with cabinet 0,
and increase sequentially.
1.3.1 Main Control Cabinet
If the 1816 system is interfacing with 60 or less phone lines, the Garden Style Cabinet will be used
since no auxiliary cabinets will be required. If the 1816 system is interfacing with more than 60, but
less than 156 phone lines, then the larger 1816 Main Control Cabinet will be used. The large main
control cabinet houses the main processor board and 5 relay boards mounted in the cabinet. A
decoder board and up to 8 relay boards can be mounted on the door of this cabinet, which is then
identified (the door side) as Auxiliary Cabinet 0.
1.3.2 Auxiliary Cabinets
Additional cabinets will be required if the 1816 system is interfacing with more than 156 phone lines.
Each cabinet physically houses two Auxiliary Cabinets; 1 Auxiliary Cabinet (decoder board and up to
8 relay boards) is housed in the cabinet and a second Auxiliary Cabinet is housed on the door side.
Since Auxiliary Cabinet 0 is housed in the Main Control Cabinet, these two Auxiliary Cabinets are
labeled as Auxiliary Cabinet 1 and Auxiliary Cabinet 2. Auxiliary cabinets are numbered sequentially
as additional cabinets are added.
