Setting up a Multi-Blade Controller
The Advance Multi-Blade controller is ideal for installing in a centralised location,
such as a riser cupboard or server room. Each controller can support up to four
Blades, enabling the connection of up to 8 doors / 8 readers, if four door Blades are
fitted. Alternatively, a combination of door and I/O Blades can be used.
The Multi-Blade Controller can be used with different power supplies: 5 Amp external
power, 8 Amp external power, PoE or PoE+. In addition, an optional 12V sealed lead
acid battery can provide backup for all connected equipment during power outages.
(Note that all data is retained when power is lost even without a battery tted).
When selecting the most suitable power supply, calculate:
The total power consumption of the controller itself, its components and fitted
Blades. This will include:
— Controller quiescent power – 3.6W, max 300mA
— Battery charging power – depends on the power supply used, e.g. for 12V 5A
PSU, assume max 6.0W (0.5A)
— Each door Blade fitted – 1.0W
— Each I/O Blade fitted – 4.0W
The total power requirements for all the locks, readers, etc. that will be connected
to all the Blades:

* Indicates the approximate power required by the controller, assuming three
Door Blades and one I/O Blade tted, and allowing for standard battery
charging power.
** PoE is not recommended for fully-populated multi-Blade controllers as it does
not provide sucient power.
