RISCO LightSYS 8 Zone Input Expander – RP432EZ8 Wired Zone Expansion Module for Alarm Systems

The RISCO LightSYS 8 Zone Input Expander (model RP432EZ8) is a reliable wired input expansion module designed to increase the number of hardwired zones in your RISCO alarm system. Compatible with LightSYS™, LightSYS™ 2, and ProSYS™ Plus panels, this expander allows for seamless integration of additional wired detectors using the RISCO system BUS. It simplifies installation by enabling parallel connections from any point along the wiring route, offering both flexibility and scalability for residential and commercial security setups.

Product Features

Expandable Wired Zone Capacity

Easily expand your existing system by adding up to:

• 3 expanders to LightSYS™
• 5 expanders to LightSYS™ 2
• 35 expanders to ProSYS™ Plus
  Each expander adds 8 wired input zones, allowing for more detectors and sensors in large or growing installations.

BUS-Based Connectivity

Utilizes RISCO’s 4-wire BUS architecture, reducing cabling complexity and supporting parallel wiring configurations—making installation faster and more efficient.

Event-Driven Output Control

Includes 8 open-collector outputs (100mA each), configurable to trigger based on system events, such as zone violations, user actions, or partition statuses. This adds automation capability for controlling relays, indicators, or external devices.

Detector Compatibility

Supports connection of any standard wired detectors (motion sensors, glass break detectors, magnetic contacts) via the expander, enhancing your system’s coverage and security depth.

Plug-and-Play Integration

Auto-identification and seamless integration with RISCO control panels ensure fast setup and compatibility without complex configuration.
