SA-4 Introduction

The SA-4 Access Control System contains the latest technology providing personnel access
to buildings, car parks, hazardous and secure areas. The system supports a broad range of
features such as anti-passback, muster control, history recall and holiday support. The system
employs an intuitive user interface which allows a high degree of programming flexibility.

The SA-4 has four major components. These are the keyboard and display interface, main
processor card, reader interface card and network interface cards. The keyboard and display
are mounted in the front door of the SA-4 whilst the remaining components are mounted on
a removable chassis for easy installation and maintenance.

The system is programmed via a QWERTY keyboard and two line forty character LCD
display. The display gives meaningful intuitive user information and prompts the user through
each stage of programming. The keyboard gives easy access to all programming keys without
the need to learn intricate key patterns required on some systems.

The main processor card contains the system microprocessor, storage memory and system
interfaces which form the intelligent core of the system. A small battery provides protection
by maintaining the systems memory, date and time during power failure. The processor card
provides interfaces for serial printers, network cards, display card and expansion modules. A
fully monitored power supply is also incorporated on the card providing three major external
supplies for readers, door locks and lead acid battery charger. Control and monitoring of
external equipment can be carried out using the eight clean contact monitor inputs and eight
relay contacts provided.

The reader interface card provides the logic to control four readers with PIN pads. Plugable
connectors allow easy maintenance. The interface supports three major reader interfaces
Watermark Magnetics™, Weigand and ABA soft magnetics. The interface is plugable to
allow support for future devices.

The network interface is provided for the interconnection of controllers within an on-line
system. A number of cards are available including RS232C, isolated RS485 and isolated
current loop modules.

The system is expandible to a full featured PC based On-line system, hosted by mouse driven
graphical software.

This manual covers the hardware installation of the controller and peripheral equipment wiring
including card readers, PIN pads and communications. This manual does not cover program­ming of the system. Refer to the SA-4 operators guide for this information.

System Description and Configuration

The SA-4 Access Control System is comprised of three major parts, the SA-4 controller, the
card reader and the card. The SA-4 controller stores all information concerning users access
rights and makes all decisions about both entry of users and control and monitoring of external
equipment. The controller supports up to four card readers and can simultaneously support
readers of mixed card technology. The system will support four points of entry using free egress
or two doors using reader entry and egress.

The simplest SA-4 system configuration would consist of one SA-4 controller and one card
reader. The SA-4 controller would be located in a position suitable to allow programming of
the card reader and door controls would be located at the point of entry. Cabling between the
card reader and the controller allows card information to be passed to the controller and status
information to be passed to the reader. Separate cabling between the entry/exit point controls
and the controller allow monitoring and control of entry and egress of card holders.

Unpacking

Remove the controller from the box and check the following are present:-

Two battery leads - one red, one black

Four inductive load suppression kits

One spare fuse

Four mounting brackets and bolts. (IP enclosure version only)

Check that all plugable terminal blocks are present and there is no damage to the equipment
before you continue with the installation.

Installation

The controller can support up to four readers and/or keypads concurrently. It is recommend
that the controller be situated as centrally as possible, keeping cabling between the readers and
controller to a minimum. If further readers are to be added to a controller after installation,
ensure that the distances between potential reader sites and the controller are taken into
account.

The chassis can be removed whilst the enclosure is being mounted in a suitable position. Two
types of enclosure are available, standard and IP rated. The standard enclosure is secured via
four holes, one in each corner of the enclosure. The IP enclosure is supplied with four mounting
brackets. These brackets have two fixing holes, one is used to secure the bracket to the rear of
the enclosure and the other is used for a wall fixing.

Mains to the unit should be supplied using an unswitched 240V 3A fused spur, cabled to current
wiring practices and fused to 3A.

Readers

Connection of readers to the unit will vary from reader to reader, however, an example
interconnection diagram which accompanies this guide gives wiring diagrams for two common
reader interfaces. Note that the reader interface only supplies 12V DC, so for readers requiring
a 5V supply a separate supply must be provided (e.g. a 5V regulator driven from the 12V line).
The interface also provides two open drain outputs which on a standard board are terminated
with 1k ohm resistors, giving 12mA drive current for the connection of LED’s. However a non­terminated version of the card is available with a sink capacity of 200mA for connection of
higher current indicators. These outputs have fixed functions. Output one is for connection to
an accept indicator and output two for a reject indicator, generally green and red respectively.

Two non-isolated inputs are available on the interface for connection of supplementary reader
signals, such as card present and time-out. These signals are not required by the system for
correct operation and are connected at the user's discretion.

MEL-TEM-011 ISSUE 1

Earthing

All cabling from the controller should be shielded and bonded to the controllers earth, with the
exception of communication cabling which is terminated at the main controller. A terminal on
the communications board is provided for the termination of communication cable shield. Note
that cables should not be bonded to more than one earth as this can cause problems.

Relay outputs

There are eight 1 amp relay outputs, with normally closed and normally open outputs. When
connecting inductive loads such as magnetic locks or door strikes, a suppression kit should be
fitted. The suppression kit contains a diode and a capacitor. The capacitor should be fitted
across the relay common and the switching terminal of the relay either N/C or N/O. This
prevents damage to the relay contacts due to arcing. The diode should be fitted reverse biased
at the load to reduce switching noise from the load. Failure to fit suppression could lead to
damage to relays and cause intermittent resetting of the controller during load switching. For
loads greater than 1 amp, a shunt relay should be provided and driven from the relays in the
controller.

Clean contact inputs

Eight isolated inputs are provided for connection of switches, relays and other voltage free
contacts. These inputs can be used for generating alarms or as general purpose inputs for
driving local or global outputs on controllers.

I/O functionality

None of the inputs or outputs provided by the controller have fixed functions. The function of
each input or output is defined from the central controller as a software script which is down
loaded to the controller. It is important to remember that controllers which have the same or
similar I/O functionality should be cabled in the same way. This will reduce the number of
scripts which have to be written during commissioning.

Keypads

Facilities for up to four keypads are provided for the connection of standard XY matrix
keypads. Up to sixteen keys are supported. The position and function of each key is defined
from the central controller. Again, it is important that all keypads are wired in the same way
to reduce the number of keypad definitions to be created during commissioning.

MEL-TEM-011 ISSUE 1

Communications

Presently, three types of serial interface are available for controllers, RS485, RS232 and
current loop. The RS485 interface is a full duplex, multi-drop topology consisting of two
differential pairs, transmit and receive, carried on standard Belden twisted pair cable. The
communications cable is daisy chained from the master controller (generally a PC based
RS485) to each controller. The cable must not be spurred or starred as this can cause
transmission problems. Each pair must be terminated at each end of the line with a quarter watt
150 ohm resistor. For connection details of the RS485 card, see the attached connection
diagram.

A standard RS232 interface is available with 9 pin delta connector termination and is suitable
for connection to line drivers, modems and direct connection to a personal computer. The
current loop interface is available which is fully compatible with Tunstall/Tann equipment.
This network topology is the same as RS485 but requires no termination resistors and can cover
greater distances. Both the current loop and RS485 cards have LED's to indicate reception of
data from the main controller. The RS485 card has both transmit and receive indicators, these
are provided for diagnostic purposes. All of the interfaces plug into the main controller PCB
via an eight pin header and are secured using four M3 screws. When fitting communications
cards, ensure that the pins are correctly positioned in the socket before the controller has power
applied to it.

Installation considerations

When carrying out any wiring or maintenance on the controller, remove mains power and if
present, disconnect the battery. The plugable connectors are provided for ease of installation
and maintenance and are not 'hot insertable' (REMOVE THE POWER!). When inserting
plugs, ensure that they are positioned correctly as it is possible to insert a plug in an offset
position, eg. pin 1 in pin 2 position. Always ensure that there are no loose wires or foreign
objects in the enclosure which could short out the circuitry. Before a controller leaves the
factory it is tested for electrical safety. This test includes an earth bonding test. If any earth
bounds are removed by the installer, the equipment must be re-tested.

When positioning the controller, locate a position which is central to installed and potential
reader sites. This will minimise reader cable lengths. When mounting the controller on the wall,
ensure that the height chosen allows the controller to be programmed comfortably by the user.

DO NOT

Exceed 100m cable length between reader and controller.

Use unshielded cable.

Use cores from a reader cable to drive inductive loads (Door strikes).

Drive inductive loads without installing suitable suppresion devices.
