Setting up a Single-Blade Controller
Page 6
The Advance Single-Blade controller is designed to be located close to a door
or when limited space is available. It has an integral case which supports either
one 2 Door Blade (supporting 2 doors and 2 readers) or one I/O Blade
(supporting up to 8 supervised inputs and 8 volt-free relay outputs).
The Single-Blade controller can be used with different power options: PoE, PoE+ or
one of a number of supported 12V external power supplies. In addition, an optional
4.2V lithium polymer battery can provide backup for all connected equipment during
power outages.
When selecting the most suitable power supply, calculate:
The total power consumption of the controller itself, its components and the Blade
fitted. This will include:
—
Controller quiescent power – 3.0W, max 250mA
—
Battery charging power – up to 2.0W, max 167mA (when battery depleted)
—
Door Blade, if fitted – 1.0W
—
I/O Blade, if fitted – 4.0W
The total power requirements for all the locks, readers, etc. that will be connected
to the Blade.
