Paradox ZC1-P2C Zone Door Contact Module

The Paradox ZC1-P2C (ZC1) is an official single-zone door contact extension module designed for Paradox security systems. Engineered for fast, concealed installation, it converts a standard magnetic contact reed switch into a system addressable zone. This allows installers to connect magnetic door/window contacts directly to the panel’s combus/communication line, expanding zone capacity without running dedicated cable wires back to the main control board.

Key System Features & Functionality

• Single Zone Input Module: Adds 1 hardwired addressable zone input for magnetic reed switches or door contacts.

• Compact In-Door/Frame Design: Miniaturized form factor allows clean, hidden installation inside door frames, junction boxes, or window mullions.

• Direct Bus Connectivity: Connects directly to the Paradox 4-wire multibus communication line.

• Supervised Zone Input: Continuously monitors zone status (Open/Closed/Tamper) and reports real-time state changes to the control panel.

• Low Power Consumption: Ultra-low current draw powered directly from the panel auxiliary/bus output.
