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 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.
Installing the SCS-100
Install the SCS-100 in any one of the SCS-RACK ve right hand positions with the card puller in the
up position. Connect the 10-position at cable from the SCS-150 processor card. The line card line
number is determined by the processor card cable it is connected to.
THE LIGHT BROWN (PIN 1) WIRE OF THE FLAT CABLE CONNECTOR MUST FACE UP ON THE LINE CARD.

Connecting the Phone Line
Install the RJ11X cable provided with the line card between the RJ11X connector on the line card front to a
customer supplied RJ jack. Use a standard 103J voice grade (analog) line. A slot is provided in the receiver back
plate for the RJ11X cable to pass through. Maximum line impedance is 100 Ohms.
The SCS-100 is registered with the FCC, registration number CCK8GW-16197-AL-N; Ringer Equivalence 1.2.
Phone Line Monitor
The SCS-100 monitors the incoming phone line voltage. During a loss of phone line voltage, the red Phone Line
Fail LED lights and the alert sounds. The alert can be silenced by pressing the silence switch on the SCS-100. The
LED remains lit until the phone line is restored.
Power Monitor LED
The green LED labeled PWR lights when the power supply on the line card is working properly.
SCS-100 LEDs
The six yellow LEDs indicate the line card condition during the various stages of communication. A description of
each LED is listed below:
TD Transmit Data On when the line card is transmitting to a panel.
RD Receive Data On when the line card is receiving data from a panel.
CD Carrier Detect On when the carrier tone from the panel is detected on the phone line.
OL On Line On when a digital dialer line card has answered the phone line.
RG Ring Detect On when ringing voltage is detected on phone line.
DT Data Terminal Ready On when the line card is ready for operation.
