Multi-Blade Controller
The 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 different
Blades, enabling the connection of up to 8 doors / 8 readers, if four Door Blades
are fitted. If using OSDP blades 8 doors / 16 readers are supported. Alternatively, a
combination of door blades, OSDP blades and I/O Blades can be used.
The Multi-Blade Controller can be used with either a 5 Amp external power supply or
an 8 Amp external power supply. PoE or PoE+ can be used to power the controller for
configuration purposes only, 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 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
fitted).
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 6W (0.5A)
▪
Each door Blade fitted – 1W
▪
Each I/O Blade fitted – 4W
▪
Each OSDP Blade fitted – 1W
The total power requirements for all the locks, readers, etc. that will be connected
to all the Blades:
