The related 622 is the dual‑circuit variant in the same family, offering expanded wiring within the same form factor. These Series 600 heat detectors are described as attractive and durable, built to withstand demanding environments while delivering reliable heat‑based detection when coordinated with a compatible fire alarm system. The sensor combines a rate‑of‑rise element with a fixed‑temperature element to trigger alarms on rapid heat buildup or after a sustained high temperature, making them suitable for mechanical rooms, electrical spaces, warehouses, and other areas where smoke detectors may be unsuitable. They are intended for use within life‑safety networks in accordance with applicable standards, with NFPA 72 guidance referenced in Chemetronics manuals for application requirements. \u003c\/p\u003e\u003c\/div\u003e","brand":"CHEMETRONICS","offers":[{"title":"New","offer_id":51677983277358,"sku":null,"price":160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_923a7b72-f815-4911-8347-29bc372d7d81.jpg?v=1769570302","url":"https:\/\/plgautomation.com\/products\/industrial-chemetronics-602-heat-detector-622-series-600-fire-alarm-heat-detector","provider":"PLG Automation ","version":"1.0","type":"link"}
