Its mechanical layout provides mounting capacity for seven local rail modules while also supporting as many as two compatible power supplies and a half-footprint module within the designated chassis area. The assembly installs inside compatible EST3 lobby enclosure wallboxes and provides the physical framework needed to organize interconnected control, communication, display, and power components. Because the chassis, enclosure backbox, doors, rail modules, and system electronics are selected according to the required EST3 configuration, the 3-CHAS7 supports flexible panel construction without functioning as an independent electronic control device.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eSeven Local Rail Positions: Provides mounting space for up to seven compatible EST3 local rail modules.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDual Power Supply Capacity: Accommodates as many as two compatible EST3 power supply assemblies.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eHalf-Footprint Module Space: Includes capacity for one compatible half-footprint module within the chassis arrangement.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSingle Chassis Space: Occupies one designated chassis position within a compatible EST3 enclosure.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eEST3 System Compatibility: Designed specifically around the modular mechanical architecture of Edwards EST3 systems.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eModular Panel Configuration: Allows control, communication, interface, and other local rail modules to be arranged according to system requirements.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eIntegrated Equipment Support: Provides a common mounting structure for both system electronics and associated power equipment.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLobby Enclosure Integration: Designed for installation within compatible EST3 lobby enclosure wallboxes.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eService-Oriented Layout: Organizes modules within the cabinet for installation, wiring, inspection, and maintenance access.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDurable Construction: Provides the rigid mechanical support required for permanently installed life-safety control equipment.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eExpandable Architecture: Supports the scalable EST3 approach in which chassis and module combinations are selected for individual system requirements.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePassive Mechanical Assembly: Requires compatible EST3 modules and power supplies to provide system functionality and does not operate independently.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eThe 3-CHAS7 delivers the reliability and precision required for organizing and supporting modular electronics in Edwards EST3 fire alarm and life-safety control systems.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp id=\"p-rc_c7b8f4fae39e183e-25\"\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Edwards","offers":[{"title":"Default Title","offer_id":52804688412970,"sku":"3-CHAS7","price":362.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l1200_c47ecf09-764a-4f7c-8d5d-629743852559.jpg?v=1790792758","url":"https:\/\/iqelectro.com\/products\/edwards-est-3-chas7-est3-7-module-fire-alarm-control-panel-chassis-assembly","provider":"IQElectro","version":"1.0","type":"link"}
