System Overview
Description
The SCS-1R Security Control Receiver system from DMP is a full featured digital dialer and data network capable
alarm receiver. The receiver provides a 32-character LCD display for viewing incoming messages and a built-in
membrane keypad for acknowledging messages and conguring the SCS-1R system.
Function
The SCS-1R Receiver system provides central stations with computerized monitoring of DMP panels. Features of
the SCS-1R include automatic alarm, trouble, and supervisory account message logging on a local printer including
the date and time of their occurrence. The SCS-1R also provides an output to most security automation software
packages.
32-Character LCD Membrane Keypad
The built-in LCD display and Membrane Keypad add exibility to the SCS-1R system by allowing the operator to
view alarm messages before acknowledging them from the built-in Membrane Keypad. A typical alarm message
includes the account number, zone name, and alarm type with the time and date of the occurrence. Alarm
messages display on the LCD and print to the local printer.
Printer
Routine messages print without the need of operator response while non-routine messages print and display on
the LCD for operator acknowledgment.
Note: UL central station applications must use a serial printer that is listed for Fire Protective Signaling
Systems.
Additional Messages
Other messages transmitted to the SCS-1R by DMP Command Processor panels include:
• Operator code number additions and deletions including the name of the person making the change
• Zone bypasses and resets by name and number including the name of the person making the change
• Schedule changes including the name of the person making the change
• Trouble and Restoral message by zone name and number
• Door access reports including the user name and the number of the door being accessed
The Printout Explanation section of this guide provides a description of the SCS-1R alarm and activity messages
that print and display.
24-Hour Recall Tests
The automatic recall test from a digital dialer account must be tracked manually or with a listed automation
system. The SCS-1R Receiver does not automatically indicate a delinquent recall test. Failure to receive a signal
from a Digital Alarm Communicator Panel (DACT) over a 24-hour period is handled by the automation system.
Line Capacity
The SCS-1R Receiver accommodates up to ve incoming phone lines. The account range for Digital Dialer panels is
1 to 65,535.
To select the communication type used on each incoming line, refer to Congure System in the Operator’s Guide
section of this guide.
Number of Standard or Encrypted Line Security Network Accounts
The maximum number of accounts with standard or encrypted line security and substitution using 6-minute
checkin that can be received by a single SCS-101 Line Card is 3200.
Opening and Closing Signals
The total capacity of opening or closing signals per SCS-1R Receiver, limited by automation system using 19200
baud and acknowledgement speed of 100 milliseconds, is 300 per minute.

Model SCS-100 Line Card
Description
The SCS-100 provides for one incoming line of digital dialer (DD) communication to DMP Command Processor™
panels. Each line card includes one 10-position at cable for processor card connection, and one RJ11X cable for
phone line connection from a customer supplied RJ11X connection block.
Transmit Level
The Transmit Level is the level of signal strength at which the SCS-100 transmits through the phone line. To adjust
the transmit level, place the 2-pin jumper on the desired level on the J11 Transmit Level header.
The Transmit Level comes from the factory set to -9 dB. -9 dB is the quietest, 0 dB is the loudest.
Echo Cancel Off
Echo Cancellation is technology used by telephone companies to stop echo from interfering with digital telephone
transmissions. In some cases this technology can interfere with alarm signals. If you have problems with Echo
Cancellation interfering with your signals, place the 2-pin jumper on the J12 Echo Cancel Off header to the
YES position to turn off the echo cancellers. If you are not having problems with the telephone company echo
cancellation, leave the jumper on the default setting of NO to leave the echo cancelers on.
