Fusible Links. <br /> <br />The fusiole link is designed to separate at a specific temper- <br />ature. releasing tension from the fusible link line, causing <br />system actuation. See Figure 2.12. <br /> <br /> <br /> <br />Figure 2-12.

Thermal Detectors. <br /> <br />Rate compensated temperature thermal detectors are nor- <br />mally open, mechanical contact closure switches designed <br />to operate at a factory preset temperature. They are avaiJ. <br />able in six preset temperatures which meet NFPA standards <br />and are UL Listed and FM Approved. After determining the . <br />maximum ambient temperature at the thermal detector loca- <br />lion, selecl the correct thermal detector according to the <br />tem;JeralUre condition ohart below: <br /> <br />Thermal <br />Detector <br />Model No. <br /> <br />TO.140 <br />TD-190 <br />TO-225 <br />TD-325 <br />TD-450 <br />TO-SOO <br /> <br />Maximum Ambient <br />Temperature <br /> <br />70' F.
