SCS-104 Line Card
Provides four digital dialer (DD) lines and a network connection for communication to DMP panels.
The SCS-104 provides four digital dialer (DD) lines and a network connection for communication to DMP panels. Each card includes one shielded eight-pin modular connector (J1) for the digital data network connection. This allows the SCS-1R Receiver to accept alarm and system messages over a network from DMP panels. Each card also includes a non-shielded eight-pin modular connector (J3) that supports up to four digital dialer lines, when connected to a standard RJ61 jack.

Version 103 | October 16, 2017
Send Stored Messages (XT30/XT50 and XTLplus Only)
SCS-104 Version 103 (10/16/17) supports the Send Stored Messages feature of upcoming panel firmware Version 172. If Send Stored Messages is enabled, an XT30/XT50 or XTLplus Series panel with Version 172 firmware will store any messages that are not able to be sent while communication to the receiver is down. Once communication is restored, the panel will send all stored messages to the receiver. Each stored message provides the number of minutes ago the event occurred. This feature requires upcoming SCS-150 firmware Version 104.
Receiver Check-In Messages (XT30/XT50 and XTLplus Only)
This feature supports upcoming panel firmware Version 172 and requires SCS-150 firmware Version 104. Prior to Version 172, if a panel failed to deliver a check-in message to the receiver on IP1, the panel attempted to send a check-in message on IP2.
If IP2 was programmed to communicate with a different line card, that line card would generate an S17 (communication restored) message. Depending on the programmed fail time, the line card pointed to by IP1 could also generate and S16 (communication failed) message.
If the line card pointed to by IP2 was different, then on the next successful check-in attempt to IP1, that line card would generate an extra S16 (communication failed) message.
Beginning in panel firmware Version 172, the panel sends a special check-off message to the receiver’s IP2 once communication is restored to IP1. This improvement prevents the SCS-104 from generating an extra S16 (communication failed) message after communication with IP1 is restored. Send Stored Messages must be enabled in the panel for this feature to be available.
Panel Communication
The SCS-104 has been enhanced to allow for better panel communication when dealing with low signal levels caused by bad phone lines, carrier exchanges, and other issues.
TCP Session Reset
SCS-104 cards now automatically reset TCP sessions where panel communication is lost for more than 15 seconds. When a bad session is reset, the inactive socket is closed and the card resumes accepting network communication.
Caller ID Display
With Version 103, SCS-104 cards now collect caller ID information when the calling number is delivered in the message field.
Subnet Mask
The SCS-104 has been updated to allow the subnet mask to be used independently from the IP address. Previously, the SCS-104 would ignore a class B subnet mask if the IP address was 192.X.X.X or higher.
Card Reset
An issue where the SCS-104 would intermittently reset itself has been resolved.
