To give a constant tension on the wire rope during installation of the detector linkage, hang a vice grip or other weighted device on the excess stainless steel wire rope, leaving an ade- quate length of spare wire rope between the locking clamp and the weighted device. Install the linkage and the correct ANSUL approved fusible link in the remainder of the detector brackets.
