Single-Blade Controller
The 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) or one OSDP blade (supporting up to 2 doors
and 4 readers).
The Single-Blade controller can be used with different power options: PoE, PoE+ or
one of a number of supported 12V external power supplies, please do not use mains
power and PoE or PoE+ together as the controller will use the first available power
supply it finds when powering up, for example if PoE and external mains the PoE
will be seen first and the external mains ignored. Disable PoE on the switch if not
required. 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 – 3W, max 250mA
▪
Battery charging power – up to 2W, max 167mA (when battery depleted)
▪
Door Blade, if fitted – 1W
▪
I/O Blade, if fitted – 4W
▪
OSDP Blade, if fitted – 1W
The total power requirements for all the locks, readers, etc. that will be connected
to the Blade.
