INTRODUCTION
The SCS2 is a multi-line, multi-format digital receiver for
commercial fire and burglary. The basic unit consists of up
to 15 individual line card modules (SCS2-200) and 30 telco
lines connected to a SCS2-300. The SCS2 can decode a variety
of popular and widely used communication formats. Refer
to Appendix A, SCS2-200 Communication Formats for a list
of the available communication protocols.
The SCS2’s real-time clock and calendar stamps all information
received with the time and date, and all information can be
printed and/or forwarded to a computer. To ensure security,
adjustment of the clock, calendar and other programming is
password-protected.
SCS2-300
The SCS2-300 Central Processing Module oversees operation
of the line cards. Along with its built-in keypad and LCD
message screen, the SCS2-300 features one parallel printer
port, and two COM Ports.
SCS2-200
Each SCS2-200 module can monitor two telephone lines. The
line card module is equipped with a 256-event non-volatile
memory buffer to record events and corresponding telephone
numbers. Caller Source capability is built-in and telephone
numbers can be printed out, sent to automation and stored
in memory. Events and information stored in memory can be
printed at any time. Each line card also features flash EPROM
uploads through the Debug port for software upgrades or
options programming.
SUPERVISION
The standby battery voltage and connections are supervised.
The line cards are also continuously supervised to ensure
uninterrupted communication with the SCS2-300. Any trouble
conditions are reported on the LCD screens and sent to the
printer and the computer.
The SCS2-200 line card module also verifies communications
with the SCS2-300. In the event of a malfunction, the operator
will be advised with a visual indication and the line cards will
continue to function. Each line card will continue to receive
information.
The printer is supervised for loss of power, off-line, paper
out and other trouble conditions. The communication link to
the computer through the RS-232 port is monitored by the
supervisory “heartbeat” test transmissions.
COMPATIBILITY
Central station automation software packages such as
M.A.S., DICE, SIMSII, S.I.S., GENESIS and MICROKEY
support the SCS2 DMP interface. Compatibility with the automation
software in a system used at a central station is intended to
be handled under a separate UL 1981 software package and/
or site certification evaluation.
SCS2-300 OUTPUTS/INPUTS
The SCS2-300 features three switched-negative outputs. One
output labeled “OPTION” has a corresponding LED on the
SCS2-300 front panel; the factory default programming slowly
flashes the OPTION LED when the “OPTION” output is activated.
Switched negative outputs are also provided for the
Acknowledge and Trouble LEDs.

VIRTUAL RECEIVER ARCHITECTURE
The most novel feature of the SCS2-200 is its ability to use
the telephone company information delivered as DNIS (Dialed
Number Information Service) or Caller ID. This allows the
DMP Format Expert System to handle on the fly each received
call. With this feature, dedicated line pool hardware is
eliminated. Instead, the DNIS or Caller ID information allows
dynamic options that set up virtual line pools to identify
security formats and extend account numbers.
Standard DNIS is supported up to 10 digits. Each dialed
number should be assigned to a virtual receiver. Multiple
Caller ID numbers can be assigned to a single virtual receiver.
Each dialed number would formerly have been a line pool
on conventional line cards.
NUMBER OF LINE CARDS SUPPORTED
The system will support a maximum of 15 line card modules
concurrently connected.

Data Reception
During data reception, a message similar to this will be displayed:
In Communication
1234 56
If valid Caller Identification information is received, a message
similar to this will be displayed:
TEL:[phone]
1234 56
The SCS2-200 decodes all information received and stores
the information in its event buffer. When a valid signal is
received, the SCS2-200 sends a kissoff signal and transmits
the decoded alarm signal to the computer and then to the
printer through the SCS2-300.
Options [1D] and [1E] can be adjusted to allow the SCS2-200
to compensate for weak signals or noisy telephone lines;
refer to “SCS2-200 Programmable Features”for information
on programming these options.
The SCS2-200 will send each message it receives to the
printer for review by the system operator. Two messages
may be sent to the printer to indicate reception problems:
“Invalid Report”and “Communication Fail”.
INVALID REPORT MESSAGE
When this problem is encountered, the following information
is transmitted to the printer and the computer:
Printer: L01- 0000-INVALID REPORT TIME:DATE
Computer: 0RRL[#0000 | NYNRRLL]
NOTE: The first RRL is subject to the line card length
option.The second RRLL is the receiver and line card
number, both in HEX.
This output for account code “0000”indicates that data has
been received, but is not valid (for example, there are
unmatched rounds or the wrong parity). The following is an
example of faulty data received by the SCS2-200, and the
printer output generated:
Round Data Received Printer Output
1st 123456 [No printout]
2nd 123446 ?1234?56 Invalid Report
?1234?46 Invalid Report
3rd 123356 ?1233?56 Invalid Report
4th 123456 ?1234?56 Invalid Report
5th 123346 ?1233?46 Invalid Report
?????10 Invalid Report
NOTE: There is only 1 invalid report at the end of a call.
COMMUNICATION FAIL
When this problem is encountered, the following information
is transmitted to the printer and the computer:
Printer: L01- 0000-COMMUNICATION FAIL TIME:DATE
Computer: 0RRL[#0000 | NYCRRLL]
NOTE: The first RRL is subject to the line card length
option. The second RRLL is the receiver and line card
number, both in HEX.
This output indicates that a call was received, but no data was
detected. The call may have been a wrong number, or the
calling control panel was unable to connect with the receiver’s
handshake.
CALLER ID
If an Invalid Report or Communication Fail occurs, and
Caller ID is enabled, the printer messages will be similar to
the following:
Fault Data: “??????10 5551212”
Fault Call: “??????40 5551212”
Note that “?”represents the missing data; “5551212”represents
the originating telephone number.
Stopping Data Reception Manually
To cancel communications between the SCS2-200 line card
and the calling control panel, press the [CANCEL] button.
Pressing the [CANCEL] button will hang up the line. This
feature can be used to hang up on a control panel that is
repeatedly sending alarms.

11
PROFILES
The SCS2-200 will load unique “profiles”in order to effectively
communicate with control panels. A profile is a set of pre-pro-
grammed line card options unique for a particular “Calling ID
Number”or DNIS number. The “Calling id”or “DNIS”will point to a
particular profile, which will then be loaded into the line card at the
beginning of each call.
Each SCS2-200 can have a maximum of 64 profiles. To change the
options for a particular profile, utility software is provided. This
software will allow the user /operator to edit the profiles.
STATIC OPTIONS
Option [01]: Line Card Number
The Line Card Number provides a virtual identification code
for each SCS2-200 module. Hexadecimal numbers “01”to
“1E”can be programmed in Option [01] to identify line
cards. [Defaults are 0D and 0E]
Option [02]: Line Card Number Length
This option is used to determine how many digits from the
line card number will be sent to the output. You also have
the option of displaying the number in hex or decimal.
Program option 02 with one of the following:
01 Send only one hex digit to the printer or computer
output (If you have a 2 digit line card number, only
the last digit will be sent to the output).
02 Send 2 hex digit line card number to the output.
03 Send 3 hex digit line card number to the output (leading
zeros will be inserted prior to the line card number).
0A Send 2 digits receiver number in decimal. 3 digits line
number in decimal.
0D Send 2 digits receiver number as programmed. Send
3 digits line card number in decimal.
0E Send 2 digits receiver number in Hex. Send 1 digit
line card number as follows:
Line Card # Send
1..F 1..F
10..1E G..U
NOTE: When using the SCS2-200, the Line Card Number
Length option should always correspond to the number
of DNIS digits being received.
For example, if 5 digits are being received then the Line
Card Number Length Option should be programmed to 3
so that 1RRLLL would be overwritten by the 5 digits of
DNIS to become 1ddddd. [Default is 0E]
Option [04]: 2-Way Audio Activation Time
Option [04] determines how long, in 10-second increments,
the 2-Way Audio function will be active once it is initiated.
At the end of this time, the line card will hang up the line.
Program a value from “01”to “FF”for 10 to 2550 seconds.
Three minutes (set option 04 to 12) is the recommended
length of time for the 2-Way Audio activation time.
To disable the 2-Way Audio feature, program Option [04]
as “00”.
NOTE: For UL Listed installations program time maximum
20 seconds.
[Default is 00]
Option [05]: Pre-Handshake Delay
When the line card seizes the line, it will wait the time
programmed at option [05], then send the first handshake.
The time programmed (hex) at this location will be multiplied
by 100 ms –e.g., 100 ms, 200 ms etc.
The default setting is 0A, for 1 second.
NOTE: If DNIS is used, this time will not start until DNIS
is received.
[Default is 00]
Option [0F]: Mute Buzzer Option
Operation of the line card’s buzzer may be programmed as
follows:
00 Buzzer sounds for line fault, SCS2-300 error, or if an
alarm occurs during a SCS2-300 error
01 Buzzer does not sound for any event
02 Buzzer sounds for audio, line fault, SCS2-300 error,
or if an alarm occurs during a SCS2-300 error
03 Buzzer sounds for all status change conditions
[Default is 00]
Option [10]: Keep Last Message On
To have the last alarm message retained on the SCS2-200
display, enable this option with a setting of 01.
Option [11]: Hook-flash Enable/Disable
Enables or disables ability to hook-flash the phone lines and
determines its duration in increments of 10 ms.
If programmed as 00, the option is disabled. If set to anything
else, you multiply the decimal equivalent of the hex value
by 10ms and that is the duration.
For example, if a hook-flash time of 500 ms is wanted, program
option [11] to 32 hex. 500 ms/10=50, 50 Dec=32 hex.
[Default is 00]
Option [12]: Caller Source Selection
Option [12] allows the line card to receive Caller ID data or
DNIS that is transmitted after the first ring on the telephone
line.

[Default is 00]
DEFAULT DYNAMIC OPTIONS
The SCS2-200 uses a unique DMP communication format to
transmit data through the SCS2-300 to the central station
computer. Event codes corresponding to alarm codes in 10
to 40 Baud formats and DTMF 4/1 to 4/3 formats are used
in this unique format to enable the computer software to
determine alarm types.
Options [30] - [3F]: 3/1, 4/1 Format Event Codes
The SCS2-200 will use the last digit of data received in 3/
1 and 4/1 formats to determine the computer event code.
The event code will then be transmitted to the central
station computer. Refer to the SCS2-200 Decoding Library
for the complete set of event codes used by the SCS2-200.
In Sections [30] through [3F], program ASCII codes according to
the Decoding Library. Values other than 20-7F (ASCII) will not be
accepted. Note that the old value programmed in each Option
will not be changed until a command with valid data is received.
Default settings are as below:
•30-38: 41 •3A: 41 •3C: 43 •3E: 52
•39: 52 •3B: 4F •3D: 5C •3F: 54
Options [40] - [4F]: 4/2 Format Event Codes Selection
The SCS2-200 will use the first digit following the account
code in 4/2, 3/1 extended, 4/1 extended, or 3/2 formats to
determine the computer event code. The event code will
then be transmitted to the central station computer. Refer
to the “SCS2-200 Decoding Library”for the complete set of
event codes used by the SCS2-200.
In Sections [40] through [4F], program ASCII codes according to
the Decoding Library. Values other than 20-7F (ASCII) will not be
accepted. Note that the old value programmed in each Option
will not be changed until a command with valid data is received.
Default settings are as below:
•40-48: 41 •4A: 41 •4C: 43 •4E: 52
•49: 52 •4B: 4F •4D: 5C •4F: 54

13
Options [50] - [5F]: 4/3 Format Event Codes Selection
The SCS2-200 will use the fifth digit of data received in 4/3
and 4/2 extended formats to determine the message and event
code. The event code will then be transmitted to the central
station computer. Refer to the “SCS2-200 Decoding Library”
for the complete set of messages and event codes used by the
SCS2-200.
In Sections [50] through [5F], program ASCII codes according to
the Decoding Library. Values other than 20-7F (ASCII) will not be
accepted. Note that the old value programmed in each Option
will not be changed until a command with valid data is received.
Default settings are as below:

•51: 41 •55: 4F •59: 52 •5D: 42
•52: 41 •56: 54 •5A: 54 •5E: 48
•53: 41 •57: 41 •5B: 43 •5F: 5C
Option [60]-[6F]: See APPENDIX D
Option [70]: Automation Common Event Code
Some central station software packages are unable to process
the alarm using the event codes listed in the SCS2-200 Decoding
Library. Where a central station monitors thousands of accounts
belonging to different companies, the same reporting codes
may have different meanings depending on the company.
Because of this, the individual event codes in Options [30]
through [5F] cannot accurately represent the alarm condition.
To overcome this, Option [70] may be programmed as follows:
Program Operation
00 Use Individual Event Codes to computer
20, 30-39, 41-5A Use Common Event Codes (space, 0-9, A-Z)
When using Common Event Codes, it is recommended that
either hexadecimal code “5A”(ASCII “Z”) or hexadecimal
code “41”(ASCII “A”) be used.
The “Space”character (Hex 20) can be used as the common
event code with certain automation software packages to
avoid account code database changes when switching over
from other brand receivers to the DMP receiver.
Note that Option [70] is ignored when using Modem formats,
Contact-ID, ACRON, FBI Super Fast, BFSK, ADEMCO Super
Fast and SK FSK1, 2 formats. [Default is 00]

NOTE: These options will only affect steady tone hand-
shakes.
[Default is 00]
Option [91]: Inter Handshake Duration
The SCS2-200 line card will usually wait for signals from the
control panels for 4 seconds before sending the next handshake,
if there are no signals received. In certain applications,
control panels can not wait long enough to get their own
handshake, especially if the handshake is programmed as
the fifth or later handshake.
Program Option [91] with one of the following:
00 4 second interval (default)
01 1 second interval
02 2 second interval
03 3 second interval [Default is 00]
Option [95]: 5 digits pulse
The SCS2-200 cannot distinguish between 4/1, 3/2 and 3/1
with checksum because all of them contain a total of 5
digits. Therefore, this option must be programmed to inform
the SCS2-200 which of the 3 formats may be used.
00 select 4/1 format (default)
01 select 3/2 format
02 select 3/1 with checksum format
NOTE: The printer messages for the 3-2 format are the
same as those used for the 4/2 format.
[Default is 00]

16
Option [96]: 4/1 Extended Format
Program Option [96] as “01”to combine 2 round pairs of 4/
1 extended format into 4/2 output for reporting to the
computer and the printer.
For example, with Option [96] enabled, the security control
panel may transmit the following information:
1234 3
1234 3
3333 1
3333 1
The SCS2-200 will interpret this information as: 1234 31
This format is not recommended as it occupies the telephone
line for long periods of time. The default setting for Option
[96] is “01”; when programmed as “00,”the option is disabled.
[Default is 00]
Option [97]: 4/2 Extended Format
Program Option [97] as “01”to combine 2 round pairs of
4/2 extended format into 4/3 output for reporting to the
computer and the printer. Program one of the following:
00 4/2 Extended format data is not combined
01 The panel sends: 1234 051234 05
0505 16
0505 16
The SCS2-200 will interpret this information as 1234 516,
or the panel sends: 1234 03
1234 03
3333 01
3333 01
The SCS2-200 will interpret this information as 1234 301.
NOTE: The default setting for Option [97] is “00”; when pro-
grammed as “00”, the option is disabled.
[Default is 00]
Option [98]: 3/1 extended format
Program Option [98] as “01”to combine 2 round pairs of 3/
1 extended format into 3/2 output for reporting to the
computer and the printer. (For M.A.S. software users, the
option should be programmed as “02”.)
For example, with Option [98] enabled, the security control
panel may transmit the following information:
123 3
123 3
333 1
333 1
The SCS2-200 will interpret this information as: 123 31
The default setting for Option [98] is “01”; when programmed
as “00”, the option is disabled. [Default is 00]
Option [99]: 8 Digit DTMF
The Ademco 4/1 Express format may cause conflicts with
the DMP DTMF 4/3 with checksum format or FBI Superfast
without checksum. Therefore, this option must be programmed
to inform the SCS2-200 which of the 3 formats may be used.
00 DMP DTMF 4/3 with checksum
01 Ademco 4/1 Express
02 FBI without checksum [Default is 01]
Option [9A]: Error Counter
0X This option is used for pulse formats. If set to X
value, the line card will hang up after X bad
rounds.
00 Disabled [Default is 01]
Option [9B]: Echo Suppression
00 Disabled
01 Enabled: The echo suppression option will enable
the transmission of a 2 second, 2025 Hz tone from
the line card to disable echo suppression
equipment. This option will only work with panels
which require a 2225 Hz handshake.
Option [9C]: Acron RS-232
When this option is programmed as “00”, the SCS2-200 will
convert the Acron Super Fast format signal into 3/2 or 4/2
format (Ex: AAAAsXssYY[DC4]). If it is programmed as “01”
the Acron Super Fast will be sent to the computer as follows:
9RRLssssAAAACCCCCCCCC[DC4]
Where:
9 = Protocol number
RR = Receiver number
L = Line number
ssss = Spaces
AAAA = Account code
CCCC = Channel 1-4
CCCC = Channel 5-8
[DC4] = Terminator
Example:
•Raw data:
1578BDDDDDDD
1578BDDDDDDD
•Printer output will be as follows:
(01-001-1578-BDDDDDDD-)
•Computer output:
(901001 1578BDDDDDDD) [Default is 01]

17
Option [9D]: MODEM II RS-232
The SCS2-200 is able to decode the Modem II formats. The
handshake 0B needs to be programmed as one of the
handshakes of the SCS2-200 for the Modem II, Modem IIa, or
Modem IIb, and handshake 0E for Modem IIE or Modem IIIa2.
Option [9D] determines the protocol sent to the computer.
NOTE: This option will also affect the BFSK format only
if programmed as 00 or 01.
Option 9D: Modem II RS-232
00: 1RRLssssssAAAAXXYYYY[DC4] (6500 protocol)
01: 6RRLssssssAAAAXXYYYY[DC4] (SG protocol)
02: Modem II to SIA protocol
03: Modem II to SIA protocol, and text is decoded
and sent to printer and computer.
NOTE: please make sure the automation software sup-
ports settings 02 and 03 if the SIA protocol is desired.
[Default is 00]
Option [9F]: Ademco High Speed RS-232
When this option is programmed as “00”, the SCS2-200 will
convert the High-Speed format signal into 4/2 format (Ex:
1RRLssssssAAAAsXssYY[DC4]). If it is programmed as “01”the
Ademco High Speed will be send to the computer as follows:
8RRLAAAAsCCCCsCCCCsC[DC4]
Where:
8 Protocol number
RR Receiver number
L Line number
AAAA Account code
s Space
CCCC Channel 1-4
s Space
CCCC Channel 5-8
s Space
C Channel 9
[DC4] Terminator [Default is 01]
Option [A1]: FBI RS-232
To enable the computer FBI Superfast protocol, program
option [A1] as “01.”When enabled, the computer output
will be as follows:
JRRLssssssAAAATZZEss[DC4]
Where:
J = FBI protocol identifier
RR = Receiver number
L = Line number
s = Spaces
AAAA = Account code.
T = Zone type
ZZ = Zone number, in hex.
E = Event code
NOTE: if E=0 and T=0 : listen in.
[Default is 01]
Option [A3]: D6500 computer output
The SCS2-200 will emulate the Radionics D6500 RS-232 protocol
on pulse formats only (00 = disable, 01 = enable).
Examples:
1. 3/1 format: Account code “123”with alarm code “1”
(alarm), the computer output will be:
00 1RRLsssssss123sAss1[DC4]
01 1RRLsssssss123sAss1[DC4]
2. 3/1 format: Account code “123”with alarm code “B”
(opening), the computer output will be:
00 1RRLsssssss123sOssB[DC4]
01 1RRLsssssss123sOsss[DC4]
3. 4/2 extended (or 3/2 or 3/1 extended): Account code
“1234”with alarm code “2”on zone “1”(alarm), the
computer output will be:
00 1RRLssssss1234sAs21[DC4]
01 1RRLssssss1234sAs21[DC4]
4. 3/1 extended (or 4/2 or 3/2): Account code “234”with
alarm code “C”on zone “2”(closing), the computer
output will be:
00 1RRLsssssss234sCsC2[DC4]
01 1RRLsssssss234sCss2[DC4]
WhereRR = Receiver Number
L = Line Number
s = Space
[DC4]= Terminator
Please note that option [70] must be left as individual event
code when enabling this option. [Default is 01]
Option [A4]: BFSK RS-232
When programming option [A4] as “01”, the BFSK format
will convert its Radionics D6500 computer output to a standard
protocol output. [Default is 01]
NOTE: This option also affects the modem option [9D].
Option [A5]: 7 Digit Pulse
This option allows the SCS2-200 to select Sescoa Super
Speed or 4/2 checksum pulse. Ordinarily, the SCS2-200
cannot distinguish between these two formats, since they
are both 7 digit pulse. Program option [A5] as 00 to have
all incoming 7 digit pulse calls decoded as 4/2 checksum,
or 01 to decode as Sescoa Super Speed. [Default is 00]
Option [A7]: SK FSK2 RS-232
The SCS2-200 provides two possible outputs to the computer.
Select 00 for protocol #1 or 01 for protocol #2. Please refer
to SCS2-200 Communication Formats section (SK FSK
communication format) for more details. [Default is 00]

DMP DTMF FORMATS
DMP DTMF 4/3 and 4/3 with checksum formats provide fast,
reliable and easy-to-understand and decode data transmission.
On-line time will be greatly reduced when using 4/3 and 4/
3 with checksum formats. The 4/1 and 4/2 DTMF formats
can also be decoded by the SCS2-200.
The 4/3 with checksum format is recommended for use with
DMP and DSC security control panels.
Example:
•DMP 4/3 format
Each round pair represents a single event: AAAAEZZ
AAAA = 4-digit account code.
E= Event code.
ZZ = Zone number or user number.
