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 16 of the following supervised keypads and expansion modules to the keypad bus:
• Alphanumeric keypads
• Four- and/or single-zone expansion modules
• Single-zone detectors
• Access control modules
1.5 LX-Bus™
You can connect the following devices to the LX-Bus™ provided on the panel or by the DMP 481, 462N, 462P, 462FM,
and 472 Interface Cards up to the maximum number of LX-Bus™ addresses. See Accessory Devices in section 3.4.
• Four- and/or single-zone expansion modules
• Single-zone detectors
• Relay output expansion modules
• Graphic annunciator modules
1.6 Outputs
The XR500/XR500N provides 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 XR500/XR500N also provides 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.
