How to Install the ISONAS PureIP Reader-controller
2: WIRING AT THE DOOR AND READER-CONTROLLER
2.1
: POWERING THE READER-CONTROLLERS
All ISONAS Reader-controller models require a direct connection to a power source.
The Pure IP Reader-Controllers can be powered with 12 volts DC or PoE (IEEE 802.3af) power
and the supply must be regulated. Many brands of power sources work well with ISONAS
equipment. Please note that you should never connect 24VDC to the reader-controller. This will
void the unit’s warranty.
2.1.1
: POWER OVER ETHERNET (PoE) OPTION
If you are installing ISONAS Pure IP Reader-
Controllers, then you can use the Power Over
Ethernet (PoE) option. PoE allows one cable to
supply data and power to the Reader-controller,
which in turn, can then supply 12VDC to the door’s
Electronic lock. The obvious savings here is that
you only need to run a single CAT5/6 cable to the
door which will provide enough power to run both
the ISONAS Reader-controller and an electronic
lock.
If your network switches do not support PoE, then
a PoE Injector can be used to augment the switch’s
output with PoE power. A PoE injector is normally
located close to your existing network hub/switch,
and the PoE Injector itself is plugged directly into a
standard AC outlet, or for extra reliability, a UPS
with battery backup.
Figure 3 is an overview of how to use PoE to
power both the ISONAS Pure IP Reader-Controller
and an electronic locking mechanism.
