Paradox SP-5500 central unit is an alarm control panel designed to manage intrusion detection systems in residential and commercial environments. The unit functions as the main processor for connecting sensors, detectors, keypads and communication modules, enabling centralised handling of alarm inputs and outputs and coordination of system arming and event reporting.

Advantages

The Paradox SP-5500 central unit provides a compact platform for integrating multiple wired and compatible peripherals, offering reliable processing of alarm events and clear interface with user keypads and external communicators. Its architecture supports standard alarm zones and outputs, allowing centralised configuration and straightforward system expansion without complex rewiring. The device is compatible with common intrusion detection workflows and is built for continuous operation in typical residential and light commercial installations.

Suitable for

• Residential perimeter and interior intrusion detection
• Small to medium commercial premises requiring central alarm processing
• Integration with wired sensors, sirens and keypad control panels
• Installations that need a reliable on-site alarm processor and event routing

Key specifications

• Function: Central alarm control processor for intrusion detection systems
• Connections: Interfaces for multiple wired zones, alarm inputs and outputs, keypad and communicator links
• Compatibility: Designed for use with standard wired sensors, detectors, sirens and compatible keypads
• Installation: Wall-mountable control panel enclosure suitable for indoor use
• Power: Requires appropriate mains power supply and battery backup per installation requirements

How to use

Install the Paradox SP-5500 central unit in a secure, accessible indoor location and connect the mains power and battery backup according to local wiring codes. Run wiring from sensors, detectors, sirens and keypads to the designated zone and communicator terminals, following the manufacturer's connection diagram. Program zone types, entry/exit delays and output behaviour using the compatible keypad or configuration software, then test each sensor and output to confirm correct operation and alarm reporting.

Usage recommendations

Use appropriately rated backup batteries and a reliable mains supply; perform periodic functional tests of sensors, zones and communication paths. For installations with remote monitoring or alarm reporting, verify communicator settings and notification paths after initial setup. Engage a qualified security installer for complex configurations, integration with other systems, or when local regulations require certified installation.
