Y2K Compliance Statement
Cat Series Control Access Equipment is designed to be used prior to, during, and after the calendar year 2000 A.D.,
and Cat Series Control Access Equipment will operate during each such time period without error relating to date data,
specifically including any error relating to, or the product of, date data which represents or references different cen-
turies or more than one century.
Cat Series Control Access Equipment will not abnormally end or provide invalid or incorrect results as a re-
sult of date data, specifically including date data which represents or references different centuries or more
than one century;
Cat Series Control Access Equipment has been designed to ensure year 2000 compatibility, including, but not
limited to, date data century recognition, calculations which accommodate same century and multi-century
formulas and date values, and date data interface values that reflect the century;
This statement should not be taken to mean that Cat Series Control Access Equipment corrects any errors gen-
erated by your computer, it’s BIOS (Basic In Out System), or your operating system or any other program or
auxillary equipment attached to the Cat Series Control Access Equipment that you have or use.
Definitions
Four Digit Year Format
shall mean a format that allows entry or processing of a four digit year date: the first two digits will designate
the century and the second two digits shall designate the year within the century. As an example, 1996 shall
mean the 96th year of the 20th century.
Leap Year
shall mean the year during which an extra day is added in February (February 29th). Leap Year occurs in all
years divisible by 400 or evenly divisible by 4 and not evenly divisible by 100. For example, 1996 is a Leap
Year since it is divisible by 4 and not evenly divisible by 100. 2000 is a Leap Year since it is divisible by 400.
Year 2000 Compliant
shall mean that the data outside of the range 1990-1999 will be correctly processed by Selcom 2000 including
application programs, files and databases.

The Select Engineered Systems
Cat Series 4 Entrance Expansion Module
The Cat Series 4 Entrance Expansion Module operates as
a remote reader controller,with requests sent through a RS485
three wire loop from a CAT SERIES Unit ONLY. Wiegand in-
puts are sent to the CAT Card Access Unit where they are
checked and will activate the correct entrance relays if autho-
rized. The expansion module may be selected to Fail Secure or
Fail Safe.
Fail Secure means the relays are normally de-energized
and energize on command. When power fails the relays remain
de-energized not allowing a command.
Fail Safe means the relays are normally energized and de-
energize on command to open. When power fails the relays de-
energize forcing the command to open.
A local terminal block provides for local activation of the
REX (Request to Exit) and door sense inputs.
Each Cat Series 4 Entrance Expansion Module is individu-
ally assignable using a simple rotary switch to an address range
in steps of four reader groups. The entire system allows for 3
boards to be connected for a maximum of 12 external readers.
Note: If two boards are set to the same address, the readers
on BOTH boards would interact and the BOTH boards
would NOT operate.
The local terminal blocks provide opto-coupled control with
the drive voltage provided. Terminals maybe pulled to Circuit
Common using dry relay contacts or opto-transistor pull downs
with 100 ohms or less. LEDs (Light Emitting Diodes) are pro-
vided to indicate input and output conditions as well as RS485
activity.
The Cat Series 4 Entrance Expansion Module requires
power at 18VAC / 40VA. The output relays are rated 3 amps at
24V ac/dc.
A 12”L x 11.5”W x 3.5”H NEMA 1 enclosure is standard.

Standard Features for Cat Series 4 Entrance Expansion Module.
The Cat Series 4 Entrance Expansion Module contains an
addressing selector 16 position rotary switch (SW1). This sets
the address of the first reader code on the board and the other
readers follow in consecutive order ( Example: Switch Position
1 ( shown) sets the activation codes as
RLY0 = Reader 5 control,
RLY1 = Reader 5 shunt,
RLY2 = Reader 6 control,
RLY3 = Reader 6 shunt,
RLY4 = Reader 7 control,
RLY5 = Reader 7 shunt,
RLY6 = Reader 8 control
RLY7 = Reader 8 shunt.
Note: J4 is not used and is disabled.

The Cat Series 4 Entrance Expansion Module contains

and four alarm shunt relays. J5 set the relay action as
J5-Off = Fail Secure (Relay is normally off and
energizes on command ) or J5-On = Fail Safe (Relay is
normally on and de-energizes on command )
Note: R-Time is not used and is disabled.

Warning: If the jumper is moved to the 12V position and
connected to a 5 Volt Reader, the reader will be damaged,
and reader warrantys are void.

Standard Features for Cat Series 4 Entrance Expansion Module
The Cat Series 4 Entrance Expansion Module contains a
terminal block (J16) that provides an logical low output for each
relay output. They can be used to activate display LED’s on the
readers to indicate acceptance. The entrance indicated will de-
pend on the setting of SW1.
The Cat Series 4 Entrance Expansion contains a ter-
minal block (J3) to individually activate the REX (Request to
Exit) and when the input terminals are shorted or pulled to com-
mon. You may use dry relay contacts or transistor pull-downs
referenced to circuit common. Each input has a LED located
just to the right of the terminals to indicate when that input is on.
When each input is closed the output relay will be activated for
the time programmed by the Relay Timing Selector Switch and
then the relay will return to its normal state even if the input re-
mains closed.

J7 located at the bottom of the board on the right
side maybe used to turn off all the relays at once by
opening the connection. This connector is normally
shipped with a Jumper installed. This could be used with
dry contacts opening on an external signal in conjunction
with J5 settings (J5 connected is fail safe) to de-energize
the relays during emergencies.
The relay outputs are type Form C (one normally open
and one normally closed contact) rated at 3 amps 24 v
ac/dc. Each relay has a LED (light emitting diode) next to
it indicating when the relay is energized.
The BAT connections allow a backup battery to be
connected. (SES Part No. B12V) This allows the unit to
continue to operate during short power interruptions
(approx 1 hour). Circuitry is included to charge and
maintain the battery. Note: Do not use these terminals
to power other devices.

Wiring and interconnections
Power: 18 vac at 40 va. Plug in transformer supplied with
unit.
Connect at J1 with 18 GA wire to a maximum of 100 ft and
14 - 16 GA to 200 ft. Recommend using seperate trans-
formers for each unit for maximum noise isolation and pro-
tection.
RS485 connections: the Cat Series 4 Entrance Expansion
Module comunicates with CAT Series Units only, using iso-
lated RS485 connections .
Recommended wire is Belden #8771. Attach from the CAT
terminal barrier strip to J2 terminals as shown. Terminal ‘A’
is Red, Terminal ‘C’ is Black. Terminal ‘B’ is White. Note:
Termination for the RS485 connections are provided. They
must remain only on the LAST module connected. (If you
are installing only one module, the Jumpers J17 J18 RE-
MAIN).
Note: Entrance Modules and Auxilary Relay Modules
may be connected in the same RS485 line.
