Specifications

Gateway IP Address: Enter the Gateway IP Address to exit your local network. The default value is

000.000.000.000.

Subnet Mask: Enter the subnet mask assigned to the SCS-104. The default value is 255.255.255.000.

Passphrase: In order to communicate using encryption, XR550 Series and XR500 Series panels

reporting in to the SCS-104 at the receiver must have a Passphrase. This Passphrase must be

programmed into every panel reporting in to the SCS-104 at the receiver. The SCS-104 installed in the

receiver must also be programmed with the same Passphrase.

To enable encryption enter an 8 to 16-character Passphrase using alphanumeric characters. If you

leave the Passphrase blank, the SCS-104 communicates with XR550 Series and XR500 Series panels,

but the data is not encrypted. The Passphrase is blank by default.

Note: DO NOT LOSE THE PASSPHRASE. A lost or forgotten Passphrase requires that every

panel reporting in to the SCS-104 at the receiver be individually reprogrammed with a new

passphrase.

S16 & S17 Always: When disabled, the S16 Panel Not Responding message is sent to the

automation computer for each supervised account that has stopped sending check-in messages unless

50 S16 messages have been generated for different accounts within one minute. This could occur

because the network has failed. Once this occurs, S72 Network Trouble is sent and the receiver stops

sending S16 messages to the automation computer. The receiver sends S73 Network Restored and will

begin sending S16 messages after the receiver starts receiving check-in messages again.

When enabled, the S16 Panel Not Responding message is always sent to the automation computer for

each supervised account that has stopped sending check-in messages without regard to the number of

accounts generating S16 messages.

When enabled, the S17 Panel Response Restored message is sent to the automation computer each

time a supervised account checks in for the first time after installation. This also occurs at an

account’s first check-in after the receiver or SCS-104 is powered-up. Default is disabled.

Acknowledge Panel Substitution Message: When selected, the SCS-104 replies with an

acknowledgment to messages sent by substituted panels. See the Substitution Code section of the

panel programming guide for the definition of a substituted panel. The SCS-104 generates only one

S58 Alarm: Panel Substitution message to the host automation computer and receiver printer for each

substituted panel. Subsequent messages from substituted panels do not generate additional S58

messages.

When not selected, substituted panels are not sent acknowledgments for their messages. For each

message received from a substituted panel, an S58 Alarm: Panel Substitution message is sent to the

host automation computer and receiver printer.

Note: Select this option for all receiver installations except for Canadian receiver installations

where the security requirement is ULC Level 5 and then this option should not be selected.
