DETECTORS
The detector consists of three basic components: the bracket, CLIP -ON STYLE - PART NO. 56837 AND 56538
linkage, and fusible link. (Fusible links are not included and must '
be ordered separately.) The bracket holds the entire assembly `
to the mounting surface. The linkage is used to support the / 4, fusible link. The fusible link is designed to separate at a specific . LINKAGE BRACKET
temperature and release the wire rope, thereby actuating the ` NKIBLE
regulated release mechanism. ,,
There are three styles of detectors available: the clip -on style, _ , _ V 1.43
the hinged style, and the scissor style. rr 7 3
The clip -on style allows the wire rope to be strung completely HINGED STYLE - PART NO. 15373 AND 15375 V (

�
The hinged style detector requires the wire rope to be strung
to the detector bracket, and then "threaded" through the linkage LINKAGE BRACKET
assembly before continuing to the next detector bracket. , \ FUSI
The scissor style allows the wire rope to be strung completely _ LINK
through the detection system conduit and brackets first and the 1 r
detector linkage assemblies are then clipped on later. ■ •
Each style of detector consists of two types of assemblies:
The Terminal Detector (Part No. 56838, 15375, or 417368) SCISSOR STYLE - PART NO. 417368 AND 417369
includes a test link and is placed last in a series of detectors.
This detector is sometimes referred to as the end-of -line detector . BRACKET
and is thus named because it is at the point at which the wire LINKAGE Q
rope "terminates," or is anchored at the detector bracket. Only
one terminal detector is required per detection system. FUSIBLE t
