Product Manual
RLC Features
Answers calls from the JANUS system
The RLC monitors the modem, if a call is received, the RLC will check that it is connected to the
correct JANUS for Windows system. When this is established, it connects the controllers to the
line for automatic transfer of information.
Makes automatic calls to the JANUS system
The RLC polls the first eight controller addresses on the comms line, for information on what is
happening on the remote site. If one of the events listed below occurs, the RLC connects itself
to the JANUS for Windows system. After providing security and line information, the controllers
are connected for automatic transfer of information.
Compulsory dial-up from the remote site occurs if:
A controller goes off-line from the RLC
A controller requests a config reset
A controller event buffer is nearly full
A controller mains power supply fails
A controller has a tamper or lock power fail
A duress pin occurs
An input tamper occurs
An RLC tamper occurs
The RLC is powered-up
Low battery voltage is detected for the RLC
Optional dial-up from the remote site occurs if:
A programmed output group triggers a connection. This can be initiated by an action (the action
would normally take place on activation of an input).
Other features
The RLC will attempt to connect to the JANUS for Windows system every minute until it
achieves connection.
Anti-passback and action information is controlled by the RLC during periods whilst it is
disconnected from the Main JANUS for Windows site.
The standard controller metal enclosure, PSU and battery backup can be used if wall
mounting. Alternatively, the MDUI, modem-type euro enclosure can be used for desk or
shelf mounting.
The RLC can be upgraded by download from the JANUS system in the same way that
an IDC issue 9 board can.
