Hochiki DFE 135 Fixed Temperature Heat Detector

Hochiki DFE 135 Fixed Temperature Heat Detector is suited for installation where high heat output fires are
expected or in areas where ambient conditions would not allow use of other detection methods.
Heat detectors are used for property protection. Do not rely on heat detectors for life safety protection. Where
life safety is involved, smoke detectors must also be used. Heat detectors should be electronically supervised from a UL listed alarm panel.
The DFE 135 fixed temperature heat detector is suited to alarm in the presence of slowly rising temperatures. The construction of this model incorporates an over-sized heat collector protected from damage by the built-in, durable plastic guard. The DFE 135 fixed temperature heat detector used the proven snap-disc principle of operation. This bi-metal disc deflects when temperature reaches a predetermined value. The disc deflection then causes a push-rod to close the internal contact resulting in an alarm condition. The bi-metal disc returns to its normal shape when the heat subsides causing internal contacts to return to their normally open position. A standby condition is restored.
