Its front panel incorporates 12 individually programmable switches paired with 12 yellow LED indicators, while slide-in labels allow each control position to be identified according to its assigned system function. The module normally installs over an EST3 local rail module, receiving power and control signals through a ribbon-cable connection; where no local rail module is available, a 3-LDSM LED Display Support Module can provide the required mounting support. Surface-mount electronics minimize panel space and power requirements, while programmable switch and indicator assignments allow the module to support functions such as zone control, equipment status, auxiliary operations, and other application-specific commands.\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\u003e12 Programmable Switches: Provides twelve individual operator control positions that can be assigned according to system programming.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003e12 Yellow LEDs: Includes one yellow status indicator associated with each of the twelve switch positions.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eEST3 Integration: Designed for use with the Edwards EST3 fire alarm and life-safety platform.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLocal Rail Installation: Mounts over compatible EST3 local rail modules for efficient use of panel space.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eRibbon Cable Interface: Receives power and control signals from the supporting electronics through a ribbon-cable connection.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOptional 3-LDSM Support: Can be installed over a 3-LDSM LED Display Support Module when no functional local rail module is present.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eProgrammable Functions: Switches and LEDs can be assigned to system functions according to the required control strategy.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSlide-In Labels: Replaceable labeling strips allow customized identification of individual controls and indicators.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSurface-Mount Electronics: Compact electronic construction reduces physical space and power requirements within the control panel.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLamp Test Capability: LED operation can be verified through a programmed control switch or the system's node lamp-test function.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAddressable Operator Interface: The 12 switches and corresponding indicators are individually represented within the system's operator-layer addressing structure.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAnnunciator Compatibility: Suitable for compatible EST3 local and remote annunciator configurations using Control Display Modules.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan\u003eThe 3-12SY delivers the reliability and precision required for programmable operator control and yellow status annunciation in Edwards EST3 fire alarm and life-safety 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":52804716265770,"sku":"3-12SY","price":455.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l1200_727b4f5d-44e2-4e80-9eaa-6b7280583c5f.jpg?v=1790793195","url":"https:\/\/iqelectro.com\/products\/edwards-est-3-12sy-est3-12-switch-12-yellow-led-display-control-module","provider":"IQElectro","version":"1.0","type":"link"}
