How to Install the ISONAS PureIP Reader-controller
2.2.7 : LOCK WIRING -- EXTERIOR DOOR KIT
The Pure IP Reader-Controller has an optional Exterior Door Kit (EDK), which allows you to isolate
the door’s lock control circuitry on the secure side of the building.
The EDK contains a form-C relay with dry-contacts
that are rated for 3 amps of current @ 30 Volts.
It can also be used in cases where the reader-
controller is switching an externally supplied
voltage or an external control signal. Examples of
such usages include operating a 24VDC lock, or
switching a logic signal for a garage door opener.
Two methods of connecting the EDK are shown
The 1 st example shows powering both the lock and
the EDK with the Reader-controller’s PoE power

EDK Wire Conductor Preparation:
Strip back the wire insulation: .25 to .275 (1/4 to 9/32) inches
Acceptable single conductor sizes: 26 gauge to 15 gauge
Acceptable two conductors sizes: 26 gauge to 15 gauge
Note for multi-stranded conductors:
Avoid allowing any stray wire strands from contacting
the adjacent terminal block connection.
Twist the multi-strands together prior to insertion.
Lightly solder-tinning the exposed wire can help prevent stray strands.
