X-BUS

All the SPC panels can be expanded up to their maximum number of zones or

outputs using the common system expanders on the X-BUS (expansion bus).

The X-BUS bus supports a maximum distance of 400 meters between each

Expander. A complete range of Expanders covers all the security requirements.

SPCE650.100 Expander, 8 Input / 2 Outputs

The SPCE650.100 Expander extends the SPC system via X-BUS with 8 wired zones and 2

fully programmable relay outputs. The zones and outputs on the Expander function

exactly as the zones and outputs on the SPC panel.

Each zone can be configured for different zone monitoring requirements. The system

supports 4K7 resistors as standard for monitoring but does support other resistor values.

The outputs are volt free relays that provide both NO and NC terminals allowing the

greatest flexibility.

The Expander comes in a tamper protected housing and features also an X-BUS status

LED and on-board buzzer for easy device identification and extensive self-diagnostic

capabilities.
