Isolator modules should be spaced between groups of sensors or modules in a loop to protect the rest of the loop. If a short occurs between any two isolators, then both isolators immediately switch to an open circuit state and isolate the devices between them. The remaining units on the SLC loop continue to fully operate. No more than 25 devices are recommended for each group.\n\u003ch4\u003eINSTALLATION\u003c\/h4\u003e\nThe SK-ISO mounts directly into a 4” square electrical box. The box must have a minimum depth of 2-1\/8”. A surface mount electrical box (System Sensor® PN SMB500) is available from Silent Knight.\n\u003ch4\u003eIsolation Module Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e Panel controlled status LED that flashes green in normal state and is solid red in alarm\u003c\/li\u003e\n  \u003cli\u003e Isolates short circuits on an SLC loop\u003c\/li\u003e\n  \u003cli\u003e Protects the modules on the SLC loop so other devices continue to operate\u003c\/li\u003e\n  \u003cli\u003e Standard 4 inch electrical box mounting\u003c\/li\u003e\n  \u003cli\u003e SEMS screws for easy wiring UL Listed\u003c\/li\u003e\n  \u003cli\u003e CSFM Listed\u003c\/li\u003e\n  \u003cli\u003e FM Approved\u003c\/li\u003e\n\u003c\/ul\u003e\nThe SK-ISO is compatible with the following Honeywell Silent Knight fire alarm control panels:\n\u003cul\u003e\n  \u003cli\u003e6820: Addressable fire alarm control panel\u003c\/li\u003e\n  \u003cli\u003e6820EVS: Addressable fire alarm control panel with an emergency voice system.\u003c\/li\u003e\n  \u003cli\u003e6808: Addressable fire alarm control panel\u003c\/li\u003e\n  \u003cli\u003e\n\u003ca href=\"https:\/\/www.fireandsafetyplus.com\/product\/sk-6700-facp-50-point-addressable-fire-alarm-control-panel-silent-knight-by-honeywell\/\" target=\"_blank\" rel=\"noopener\"\u003e6700\u003c\/a\u003e: Addressable fire alarm control panel\u003c\/li\u003e\n  \u003cli\u003e5700: Addressable fire alarm control panel\u003c\/li\u003e\n  \u003cli\u003e5808: Addressable fire alarm control panel\u003c\/li\u003e\n  \u003cli\u003e5820XL: Addressable fire alarm control panel\u003c\/li\u003e\n  \u003cli\u003e5820XL-EVS: Addressable fire alarm control panel with an emergency voice system\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Silent Knight","offers":[{"title":"Default Title","offer_id":43246876885057,"sku":"SK-ISO","price":102.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/2465\/9009\/files\/dd798c68-217udlmfoql._sl500.jpg?v=1770771163","url":"https:\/\/www.fireandsafetyplus.com\/products\/silent-knight-sk-iso-line-isolator-module","provider":"Fire and Safety Plus","version":"1.0","type":"link"}
