System Sensor PR-1 Multi-Voltage Conventional Relay, Epoxy Encapsulated (SPDT) Relay with Activation LED

For reliable high-current switching in fire, security, and building automation systems, the System Sensor PR-1 Multi-Voltage Conventional Relay delivers consistent performance and simplified installation. This SPDT multi-voltage relay is epoxy encapsulated for rugged protection against vibration and moisture, and features a red activation LED that gives technicians immediate visual confirmation of coil energization—speeding up commissioning and troubleshooting. Engineered for common HVAC and security uses, the PR-1 handles fan and damper control, door control and air-handling unit interfaces so control panels can focus on logic and monitoring while the relay handles power switching. It performs across a wide temperature range (−40°F to 158°F / −40°C to 70°C) and mounts easily in enclosures or with double-sided tape for flexible field installations. Designed by System Sensor (Honeywell), this relay supports surveillance, monitoring, and fire system integrations where dependable switching and clear status indication matter. Add the PR-1 to your project to reduce inventory complexity and improve system uptime—contact us for ordering or integration guidance.

• Simplifies system integration: multi-voltage SPDT design supports a wide range of control panels and reduces SKU complexity for installers
• Visible coil status: built-in red activation LED provides instant verification for troubleshooting and monitoring during commissioning or maintenance
• Durable, field-ready construction: epoxy-encapsulated relay core resists vibration and moisture for reliable switching in HVAC, fire, and security environments
• High-current switching for equipment control: ideal for fans, dampers, door controls and air-handling units to offload high-current loads from control panels
• Wide operating range and warranty: operates from -40°F to 158°F (−40°C to 70°C) and includes a 3-year limited warranty for long-term reliability
