Part number:
JC4-ADV-BL-2D
C4
The Janus C4 2-Door Blade is a plug-in unit that can
be purchased with either the Janus C4 Single-Blade
Controller (Part No: JC4-ADV-C2-SNG) or the Janus C4
Multi-Blade Controller (Part No: JC4-ADV-C2-MLT).
Each 2-Door Blade enables the connection of two readers
and two doors in Janus C4 access control systems.
Clearly labelled connectors simplify the task.

Power Options
Input Power
The Janus C4 2-Door Blade draws 12V power from the
controller. The 2-Door Blade power draw is summed as
follows:
2-Door Blade Quiescent Current = 83 mA max @12V
(1.0W)
External Reader Current (200mA max @ 5V and/or
500mA max @ 12V)
External Door Lock Current (= 4A max per Lock @
12V)

External Lock Supply
For systems with 24V door locks, or locks requiring more
power than the controller can provide, the 2-Door Blade
supports an external lock power supply. This operates
automatically if available, where the Blade will nd the
external lock power supply for the locks, otherwise, it
uses internal power. This cannot be changed without
powering o.
External lock power is separate from the controller power.
It will need an independent back-up if required: it is not
supported by the controller battery.

Blade LED indicators
Status LED
The main Blade LED Indicator is used to indicate activity
and state (see also the status LED on the controller).
If the LED is continuously red, the 2-Door Blade is not
communicating with the controller.
Blade State is reported by ashing a code on the LED
every 15 seconds as follows:
5 blue ashes Board is not being monitored.
Probably no download to controller
from Janus C4
5 red ashes Wrong device type congured, e.g.
a door is dened on an I/O Blade
3 red ashes Out of range device congured,
e.g. Input 3 dened when it only
supports 2
5 green ashes No devices congured for board
5 yellow ashes Reports electrical issues, such as
current tripped, over voltage, under
voltage, over current, under current

Other LED Indicators
There are three diagnostic red LEDs on a 2-Door Blade.
Note that these LEDs cannot be seen when the controller
and Blade are in the enclosure.
LED2 – Lock 1 Power. This will be on if Door 1 on the
Blade has not been dened or if the Lock 1 power
current limit has been tripped
LED3 – Lock 2 Power. This will be on if Door 2 on the
Blade has not been dened or if the Lock 2 power
current limit has been tripped

LED4 – Reader Power (includes other connections,
such as sounders). This will be on if the Blade has not
been dened or the current limit has been tripped
