FUSIBLE LINKS <br />Four temperature ratings of fusible links are available. <br />They are of the electric solder type link which will melt at <br />a predetermined temperature allowing the two halves of <br />the link to separate. <br />e em er 200 <br />er <br />JOB LINKS <br />Four temperature ratings of the Job Links are available. They are <br />constructed of two metal struts held intension by a small, glass bulb that <br />ruptures at the appropriate temperature rating. The detector bracket <br />(P/N 12508) will support either the Globe Type 'K' fusible links or the <br />Job links, and the same detector limitations apply for both types of <br />detector. <br />Part No. <br />Response <br />Type Link Rating <br />Max.

(1.37 Kg) <br />CONDUIT OFFSET (P/N 12507) <br />The conduit offset is used to allow a smooth transition for cable runs <br />into or out of the MRM, MRM II & PRM without using pulley elbows. It <br />may be used with the detection network, manual pull stations or <br />mechanical gas valve actuation network. The use of this device does <br />not reduce the maximum number of corner pulleys allowed in the <br />system. THE CONDUIT OFFSET MAY ONLY BE ATTACHED TO <br />THE ENCLOSURE OF EITHER THE MRM. MRM II OR THE PRM. <br />FUSIBLE LINK TERMINATION KIT (PN 17515) <br />The kit consists of four major components, their part <br />numbers and quantities per kit are provided in the <br />table. The kit contains the necessary cable segments <br />and hardware for the beginning and end termination of <br />the Linear Fusible Link Detection network. <br />QTY. <br />1 EMT CONDUIT CONNECTOR 1/2" <br />1 CABLE SEG. — MRM TO 1'' LINK— 30 FEET <br />1 CABLE SEG. — LINK TO TERMINATION <br />1 HANDY BOX —1/2 CONDUIT BOX <br />MRM TO 1sT LINK <br />r , <br /> <br />24 <br /> <br />LINK TO TERMINATION <br /> <br />CABLE SEGMENT — LINK TO LINK <br />PN17354 — 24" CENTERS <br />, _____-------.. --------:\ <br />PN19155 - 12" CENTERS <br />The Link to Link cable segment PN17354 insures that the LINK TO LINK <br />links in the linear fusible link detection system are spaced at the maximum 24" centers to center distance. <br />The Link to Link cable segment PN19155 places links 12" apart center to center. It will assist in locating links <br />in the hood duct opening when the two ducts are an odd distance apart. <br />1---- 24" / 12" CENTERS <br />APPENDIX A - Page 28 of 49
