10.3 Field Wiring the 635 DRM for ANTI PASSBACK
4. IF you are wiring readers for Anti-Passback
,
use the following steps and diagram.
You
can use Sections 1 and 2 on the same DPI board or you can use two Sections on separate
boards, but they should be in the same controller enclosure.
On DPI Section-1:
1. Wire the Entry Reader
to one section of the DPI and hang it on the entry side of door.
2. Wire the Door Contact
to the same section as the Entry Reader – to CNT and COM.
3.
Wire the LOCK device
to the same section on the DPI as the entry reader. You will either wire
the lock normally open (NO) or normally closed (NC), depending on the type of lock you are
installing.
REMEMBER to install surge suppression diodes at the lock and power the lock on a separate
power supply.
On DPI Section-2:
4. Wire the Exit Reader
to the second section of the DPI and hang it on the exit side of the door.
5. Hard Wire (jumper) the CNT contact to COM
(common) on section-2 of the DPI board.
6. Wire Relay 1
(lock relay) from the normally open (NO) contact on section-2 to the REX contact on
section-1.
