This add-on receiver picks up signals from paired wireless sensors and transmits zone status to a connected control panel via its onboard relay. It is suited for residential and light commercial installations where additional zone capacity is needed beyond what the primary receiver provides. Licensed security technicians and alarm system installers are the primary trade that specifies and installs this component.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 independent zones of wireless signal reception for expanded sensor coverage\u003c\/li\u003e\n  \u003cli\u003eIntegrated relay output for direct interface with control panels and access systems\u003c\/li\u003e\n  \u003cli\u003eAdd-on design pairs with existing compatible receivers without replacing primary hardware\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for residential and light commercial panel enclosures\u003c\/li\u003e\n  \u003cli\u003eSold individually as a single unit for precise inventory and project management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an add-on expansion receiver for use within compatible OPTEX wireless receiver and repeater system configurations.

De-energize the existing control panel and receiver system before connecting the EN-4204R. Follow applicable local low-voltage wiring codes and the control panel manufacturer guidelines when integrating the relay output. Verify zone assignments and pairing with wireless sensors after installation to confirm proper signal reception before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Zones\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput Type\u003c\/strong\u003e: Relay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Category\u003c\/strong\u003e: Wireless Receivers and Repeaters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OPTEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EN-4204R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OPTEX","offers":[{"title":"Default Title","offer_id":51560778629426,"sku":"EN-4204R","price":635.93,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/optex-en-4204r-4-zone-add-on-wireless-receiver","provider":"Voomi Supply","version":"1.0","type":"link"}
