How to Install the ISONAS PureIP Reader-controller
A standard CAT5/6 cable is then run between the PoE source (Injector or switch) and the Pure IP
Reader-Controller which will be located right next to the door. The CAT5/6 cable can be up to 100
Meters (328 feet) long, including all patch cables and patch panels.
Supplying 12 VDC to Door Components from the PoE powered Pure IP Reader-Controller
When the Pure IP Reader-Controller is powered by PoE, the reader can supply 0.6 amps @12 VDC
power for external components. This DC power is available via two pigtail wires.
The Red pigtail wire is typically used to control the door’s lock. The Red wire’s 12VDC output will be
activated /deactivated when the reader is operating the door’s lock. This connection has a built-in
current limiting feature, to prevent the lock from consuming too much electrical power.
The Orange pigtail wire provides a source of continuously-available 12 VDC power. You might use
this 12VDC source to power a PIR Motion Detector located at the door location.
PoE Power Budget Calculations
When planning an installation using PoE, you need to validate that the PoE source (PoE Injector or
PoE equipped Network Switch) supplying the PoE power is sized properly for all the attached PoE
devices. To do this, you total up the power draw (in watts) of the PoE connections, and compare
that total power draw to the rated capacity of the PoE source.
Below is a chart of expected PoE power draws of the ISONAS Reader-controllers.

10.4 Watts
*** Ethernet cabling power losses not included. Losses range from being negligible for short
Cat5/6 cables, up to about 16% for 100 meter Cat5/6 cables.
To meet the Pure IP Reader-Controller’s variable PoE power requirements, the Pure IP Reader-
Controller will classify itself with the PoE source as a “Class 0” PoE device. The power usage of a
Class 0 device can range between 0.4 to 13.0 watts at the device (up to 15.4 watts from the PoE
source).
