Paradox PDX-ZX16PWR 16-Zone Powered Bus Expander Kit is a complete expansion solution designed to add 16 hardwired zones to compatible Paradox alarm control panels. Combining two ZX8 8-zone expansion modules, a metal enclosure base kit with battery and tamper protection, and a 1.7A switching power supply, this kit provides reliable, powered zone expansion for professional residential and commercial security installations.

Product Description

The PDX-ZX16PWR Powered Bus Expander Kit delivers scalable system growth by integrating two ZX8 expansion modules into a single powered enclosure solution. Each ZX8 module connects to the control panel’s combus (4-wire bus) and provides 8 additional hardwired inputs and one 50mA on-board PGM output.

Together, the two modules expand the system by 16 zones, allowing installers to significantly increase detection capacity without replacing the existing control panel. The included KIT1 metal enclosure houses the modules securely and includes a backup battery, 16VAC plug pack, and tamper protection. The PS817 1.7A switching power supply ensures stable and consistent operation.

This powered expansion kit is ideal for larger residential properties, commercial sites, and system upgrades requiring additional hardwired inputs while maintaining professional installation standards.
