Optex Zone Control Panels

Overview

The OPTEX EN-4204R is a 4-zone add-on wireless receiver with integrated relay output, designed to expand the detection and control capabilities of compatible wireless security and alarm systems.

Licensed security technicians and alarm system installers are the primary trade that specifies and installs this component. The EN-4204R is used as a supplemental receiver in wireless alarm and access control system deployments. It is applicable in residential security builds, small commercial intrusion detection layouts, and any installation where the base receiver has reached its zone limit and additional wireless sensor coverage is required. It fits within broader wireless detection infrastructure rather than acting as a standalone controller.
