SU4500 Options (cont.)
GateKeeper
GateKeeper is an optional web-based application that allows Alvarado optical turnstiles installed to be
controlled from multiple devices including desktops, tablets, mobile devices, and integrated touch screens.
GateKeeper allows the control and scheduling of most day-to-day operating functions including designating
a turnstile as entry or exit only, opening or closing a turnstile, and allowing single passage overrides for
guests or personnel that have forgotten their access card. The application also includes various other
functions. These functions include an emergency “open all turnstiles” capability that is in addition to the
emergency override / fire alarm capabilities of the SU4500. The application has tiered login levels with
three levels of security (Operator, Supervisor, and Administrator).
There are two types of interfaces to allow an access control system to operate with the SU4500:
Dry Contacts
Single passage activation and the various other inputs and outputs available to / from the SU4500 are
accessed through the I/O control board located in the Main cabinet. The required system input to the
SU4500 is a voltage free, momentary dry contact (unless otherwise indicated). Outputs to the SU4500
are also voltage-free, momentary dry contacts. In rare cases, depending on the access control system, it
may be desirable to utilize isolation relays to ensure proper system signaling. Additional information on I/O
interfacing is provided later in this manual.
TCP/IP
For select projects, a TCP/IP interface is available. This interface allows a third party access system to
communicate to / from the SU4500 using a defined TCP/IP command structure. There is an additional
charge for use of the TCP/IP interface and implementation requires programming efforts on the part of the
access system provider. Instructions pertaining to the TCP/IP interface is outside the scope of this manual.
