Inovonics EN4204R 4-zone Wireless Receiver Relays

Product Description

The INOVONICS EN4204R is a 4-zone wireless receiver with integrated relays, designed for use in professional security and life-safety system installations. It receives wireless transmissions from compatible INOVONICS devices and converts those signals into dry-contact relay outputs, allowing integration with hardwired control panels, annunciators, or automation equipment. The EN4204R provides four independent zones, each with its own relay output, giving installers a clean interface point between wireless sensors and wired downstream systems. It is typically installed by licensed security or low-voltage contractors working on commercial or residential applications.

The EN4204R fits into installations where wireless sensing devices must interface with conventional wired control infrastructure. Typical scenarios include retrofit projects where running new wire is impractical, or facilities where a mix of wireless and hardwired devices must coexist on the same control platform. Each of the four zones operates independently, supporting a range of wireless input devices in the INOVONICS ecosystem. This makes it a practical solution for access control, fire alarm auxiliary functions, or general supervised wireless monitoring applications.

Compatibility

Designed as an OEM-style component within the INOVONICS wireless ecosystem; no specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a licensed low-voltage or security systems contractor in accordance with applicable local codes and NFPA 72 where fire-alarm integration is involved. Power down the control panel and any associated equipment before making relay output connections. Follow the manufacturer product manual for antenna placement, zone programming, and supervision settings. Do not exceed the relay contact ratings specified in the installation manual for connected loads.
