I/O Control
The following inputs are available for access control system signals:
This section explains the various I/O control board inputs and outputs, and how they may be used. It is
assumed that the turnstiles are already installed and interfaced with the access control system. For access
control wiring instructions, please refer to the
SU4500 Installation Instructions.
PINS 1, 8, 15, 20 - GND (Common Ground)
Description
Common ground terminals for access control system wiring. Only for
input terminal block use.
Purpose and Customer Use
Access control system outputs that require a ground return are
connected to these inputs.
PIN 2 - ENTACC / PIN 9 - EXTACC (Card Accept)
Description
Receipt of an input contact opens the barriers for a single passage in
the appropriate direction.
Purpose and Customer Use
These are core system inputs. ENTACC (entry accept) signals the
turnstile to allow a single valid passage in the entry direction. EXTACC
(exit accept) signals the turnstile to allow a single valid passage in the
exit direction. Typically these signals are provided after the access
system determines that the card presented at the turnstile is valid for
entry. ENTACC is used on virtually every installation. EXTACC is used
in controlled entry / exit applications where users both card in and card
out.
