limitations.
1.2 Communication
• Built-in network communication to DMP Model SCS-1R Receivers (Panels with Network/Encryption only)
• Built-in 128-bit or 256-bit encrypted communication to DMP Model SCS-1R Receivers (XR550 with Encryption
only)
• Built-in Contact ID communication to DMP Model SCS-1R Receivers
• Optional 893A Dual Phone Line Module with phone line supervision
• Can operate as a local panel
Note: 256-bit encrypted messages to SCS-1R receiver only communicate when using SCS-104 Receiver Line Cards
with Version 102 or higher software.
1.3 Panel Zones
• Eight 1k Ohm EOL burglary zones (zones 1 to 8)
• Two 3.3k Ohm EOL powered zone with reset (zones 9 and 10)
1.4 Keypad Bus
You can connect up to a total of 16 of the following supervised keypads and expansion modules to keypad bus:
• Alphanumeric keypads
• Four, Eight- and/or single-zone expansion modules
• Single-zone detectors
• Access control modules
• Wireless Keypads (maximum of 4)
1.5 LX500-LX900 Bus™
You can connect the following devices to the LX-Bus™ connections provided on the panel. See Accessory Devices
section 3.3.
• Four, eight, sixteen- and/or single-zone expansion modules
• Single-zone detectors
• Relay output expansion modules
• Graphic annunciator modules
1.6 Outputs
The XR150/XR550 Series provide two Single Pole, Double Throw (SPDT) relay outputs which require the installation of
two Model 305 relays, each rated 1 Amp at 30 Vdc resistive (power limited sources only). A Model 431 Output Harness
is required to use these outputs.
The XR150/XR550 Series panels also provide four open collector outputs rated for 50mA each. The open collector
outputs provide ground connection for a positive voltage source. A Model 300 Output Harness is required to use these
outputs.
