{"product_id":"notifier-hd-601-heat-detector","title":"Notifier HD-601 Heat Detector","description":"\u003cp\u003eThe HD-600 Heat Detector is attractive, durable, and features combination rate-of-rise and fixed-temperature detectors. Heat detectors are available in 135°F (57°C) and 200°F (94°C) temperature ratings.\u003c\/p\u003e\n\u003cp\u003eRate-of-rise elements detect heat by quickly responding to rapid temperature increase. HD-600 detectors use the same reliable pneumatic rate-of-rise element used in former models, but offer added aesthetic appeal. The pneumatic rate-of-rise element responds to a rapid rise in temperature, approximately 15°F (8°C) per minute, by expansion of air within the sealed chamber faster than it can escape through a calibrated vent. The resultant increase in pressure depresses the diaphragm, causing the electrical contact to close the circuit. HD-600 rate-of-rise units have a wide spacing allowance of 50-foot (15.24-meter) centers.\u003c\/p\u003e\n\u003cp\u003eFixed-temperature elements react to heat by responding to a specific temperature setting. The fixed-temperature element uses a fusible alloy. When activated, the external heat collector drops away to provide quick visual confirmation that the element has operated.\u003c\/p\u003e\n\u003cp\u003eThe units protrude only 1-3\/8\" (34.925 mm) from the ceiling surface with a junction box mounting. They have pleasing contours and an all-white finish that conforms to ceiling aesthetics.\u003c\/p\u003e\n\u003cdiv class=\"elementor-element elementor-element-d2bd60e elementor-widget elementor-widget-heading\" data-id=\"d2bd60e\" data-element_type=\"widget\" data-widget_type=\"heading.default\"\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\n\u003ch3 class=\"elementor-heading-title elementor-size-default\"\u003eFeatures\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementor-element elementor-element-89939d6 elementor-widget elementor-widget-jet-listing-dynamic-field\" data-id=\"89939d6\" data-element_type=\"widget\" data-widget_type=\"jet-listing-dynamic-field.default\"\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\n\u003cdiv class=\"jet-listing jet-listing-dynamic-field display-inline\"\u003e\n\u003cdiv class=\"jet-listing-dynamic-field__inline-wrap\"\u003e\n\u003cdiv class=\"jet-listing-dynamic-field__content\"\u003e\n\u003cul\u003e\n\u003cli\u003eRate-of-rise and fixed-temperature.\u003c\/li\u003e\n\u003cli\u003eOne- or two-circuit, normally open.\u003c\/li\u003e\n\u003cli\u003eEasy installation.\u003c\/li\u003e\n\u003cli\u003eLow-profile design.\u003c\/li\u003e\n\u003cli\u003eVisual indication.\u003c\/li\u003e\n\u003cli\u003eOperation testing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Fredland Supply Company","offers":[{"title":"Default Title","offer_id":48235629871363,"sku":"FA-793-2","price":19.99,"currency_code":"USD","in_stock":false}],"url":"https:\/\/phishstonesproducts.myshopify.com\/products\/notifier-hd-601-heat-detector","provider":"PhishStones Products","version":"1.0","type":"link"}
