Each Expander provides built-in dual-isolators, a signal equalizer and a signal

amplifier for highest X-BUS signal reliability. In loop topology the X-BUS is split-

up into two independent spurs in case of a shortcut or interrupt, and no X-Bus

components are lost.

SPCP332.300 Smart PSU (7 Ah) with 8 Input / 2 Output Expander

The SPCP332.300 Smart PSU Expander extends the SPC system via X-BUS with a

monitored 12 V DC 2.6 A local power source for connected security devices (e.g.

Expanders on X-BUS) and battery management, 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 outputs are volt free relays that provide both NO and NC terminals allowing the

greatest flexibility.

The Expander features also an X-BUS status LED and on-board buzzer for easy device

identification and extensive self-diagnostic capabilities.

The PSU with Expander comes in a tamper protected metal cabinet with space for

optional 7 Ah battery and complies with EN50131 Grade 2.
