System Sensor PR-2 Multi Voltage Fire Relay

Product Description

The SYSTEM SENSOR PR-2 is a multi-voltage relay module designed for fire alarm and life safety systems. It provides a switched output contact that activates in response to a signal from the fire alarm control panel, with an onboard activation LED that gives technicians a clear visual confirmation of relay state. The PR-2 accepts input across multiple voltage levels, making it adaptable to a range of panel configurations without requiring dedicated voltage-matched accessories. Fire alarm technicians and systems integrators install this module to control ancillary devices such as door holders, damper actuators, fans, and elevator recall circuits.

The PR-2 is suited for commercial and light industrial fire alarm installations where a supervised, panel-driven relay output is needed to interface with building systems. It is commonly installed as part of an addressable or conventional fire alarm system wherever a dry contact output is required to trigger or shut down auxiliary equipment during an alarm condition. Its multi-voltage input compatibility makes it a practical choice for retrofit projects alongside existing panel infrastructure.

Key Features

• Multi-voltage input compatibility for use across a broad range of fire alarm control panel configurations
• Onboard activation LED provides immediate visual indication of relay status during commissioning and service
• Switched dry contact output suitable for controlling door holders, dampers, fans, and other auxiliary devices
• Compact form factor suited for installation in standard fire alarm system enclosures and junction boxes
• Designed for supervised fire alarm circuit applications in commercial and light industrial settings

Compatibility

Designed as an OEM-style relay module for use in fire alarm and life safety systems requiring a multi-voltage supervised relay output.

Installation Notes

Installation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes. De-energize the fire alarm control panel and any connected circuits before wiring the relay module. Verify panel compatibility and supervised circuit wiring requirements prior to installation. Do not install or test this device without proper authority having jurisdiction approval where required.
