System Sensor R-20E Fire Relay Steel Enclosure

Product Description

The SYSTEM SENSOR R-20E is a fire relay designed for use in fire alarm and life safety systems. It functions similarly to the R-20T model but is housed in a steel enclosure, providing added mechanical protection for the relay module. Licensed fire alarm technicians and low-voltage contractors install this device as part of a broader fire detection or suppression control circuit. The steel enclosure construction makes it suitable for installations where the relay must withstand physical contact or harsher mounting environments.

This relay is intended for use in commercial and residential fire alarm system applications where a control relay is needed to switch auxiliary devices such as fans, dampers, door holders, or other ancillary equipment. It is installed in locations requiring a relay with an enclosed form factor, and serves as a direct counterpart to the R-20T in applications where a steel enclosure is specified or required by the installation.

Key Features

• Steel enclosure provides mechanical protection for the relay module
• Functions as a fire control relay for switching auxiliary devices in life safety systems
• Shares core relay functionality with the R-20T platform
• Sold as an individual unit (each)

Compatibility

Designed as an OEM-style replacement or installation option for fire alarm system relay applications where a steel-enclosed relay module is required.

Installation Notes

Installation must be performed by a licensed fire alarm technician or low-voltage contractor in accordance with NFPA 72 and applicable local codes. De-energize the fire alarm control panel and associated circuits before beginning installation or wiring work. Follow the manufacturer product manual for wiring terminations and relay configuration. Verify all connections and system operation with a full system test after installation.
