How to Install the ISONAS PureIP Reader-controller
2.2.1 : READER-CONTROLLER CONTROL-LEADS DESCRIPTION
The reader-controller has a cable extending from its back plate that is referred to as “the pigtail”.
The pigtail consists of 8 wire leads (22 awg) which are used to connect to the various components
at the door location. Most installations do not require the use of all the leads. The typical usage
of each available lead is shown in Figure 6.

One of the wires is for a door sense switch. Another is for a REX (Request for Exit) signal coming
from a switch, infrared sensor or other REX device.
The controllers have a lock-control circuit. This circuit provides conditioned 12VDC power and can
be directly connected to the electronic lock to unlock the door when a valid credential is presented.
The usage of each lead will be detailed in the next few pages.
