Specication
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.

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)
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 congured, e.g.
a door is dened on an I/O Blade
3 red ashes Out of range device congured,
e.g. Input 3 dened when it only
supports 2
5 green ashes No devices congured for board
5 yellow ashes Reports electrical issues, such as
current tripped, over voltage, under
voltage, over current, under current
Blade LED indicators
Blade Activity is reported as follows:
Yellow icker (lasts
about 30 seconds)
Firmware download in
progress
Green blink (every 5
seconds)
Board running OK
Blue blink Read
Yellow blink Input state change
Red blink Output state change
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 dened 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 dened 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 dened or the current limit has been tripped
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.

A Fail Safe lock requires power to lock the door.
The door would be unlocked in the case of a

If an external power source is detected on power
up/reset, it is used to power the locks, otherwise
internal power supply is used. Do not connect
an external power supply while the controller is
