Janus C4 System Overview
Core Software
The JANUS C4 core software is licensed to varying numbers of Intelligent Door Controllers e.g. the base system will manage up to 04 IDCs with incremental options up to 1,000 and more.
Multiple PC Stations
Multiple Networked PCs can be used with JANUS C4 for alarm monitoring, database management and card production etc. Client PCs are licensed individually and measured by concurrent connections. The core JANUS software includes 2 x Client PC Licenses
Intelligent Door Controller
There are two types of door controller, ‘IDC-485-6/4’ and ‘IDC-E-6/4’. Each controller has the same functionality but differs in the way that it connects to the main JANUS PC/server.
The IDC-485-6/4 requires a multi-drop 2 or 4-wire comms and the IDC-E-6/4 connects directly to a TCP/IP network (ethernet). Both types of controller can be used on the same system.
eSeries Controllers
When using an IDC-E-6/4 or IPC-E-16./16 they connect directly to a TCP/IP network (ethernet) and require a unique IP address on the system.

Every IDC supports 2 readers on one door (IN & OUT) or 2 readers on two doors (IN with egress button OUT).
They also support :-
- Additional 6 alarm inputs & 4 relay outputs
- 12,000 card users at the controller (expandable to 65,000 for RS485 controllers and 110,000 for eSeries controllers)
- Processing at the door
- 230/12V dc (110V/12V dc), 2A psu with battery
back-up (includes power for 2 x 12V dc locks) - Local LED and sounder outputs
