Summary
DFE 135/190 FIXED TEMPERATURE HEAT DETECTOR APPLICATION The DFE 135/190 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
OPERATIONSTANDARD FEATURES The DFE 135/190 fixed temperature heat detector is• Choice of fixed temperature - 135°F or 190°F suited to alarm in the presence of slowly rising temperatures. The construction of this model• UL Listed ceiling spacing of 50' by 50' incorporates an oversized heat collector protected (2,500 square feet) from damage by the built-in, durable plastic guard
The DFE 135/190 fixed temperature heat detector• Self-Restoring used the proven snap-disc principle of operation. This• Heat element protected by a built-in guard bi-metal disc deflects when temperature reaches a predetermined value. The disc deflection then causes• Contact Rating of 100 mA a push-rod to close the internal contact resulting in an alarm condition. The bi-metal disc returns to its normal• Highly Dependable shape when the heat subsides causing internal• Latching LED base available contacts to return to their normally open position. A standby condition is restored

Frequently Asked Questions
What is a dfe 190 heat detector?
DFE-190, a fixed temperature heat detector suited for installation where high heat output fires are expected or in areas where ambient conditions would not allow the use of other detection methods. SOC-24VN is a reliable, high-quality Photoelectric Smoke Detector.
What is a dfe 135 heat detector?
DFE 135, a fixed temperature heat detector suited for installation where high heat output fires are expected or in areas where ambient conditions would not allow the use of other detection methods.
What is a dcd 190 fixed temperaturerate of rise heat detector?
DCD-190 fixed temperature/rate-of-rise heat detector is suited for installation where high heat output fires are expected or in areas where ambient conditions would not allow the use of other detection methods. Heat detectors are intended for the protection of property.
What is a fixed temperature point for a heat detector?
The most common fixed temperature point for electrically connected heat detectors is 58°C (136.4°F). Rate-of-Rise (ROR) heat detectors operate on a rapid rise in element temperature of 6.7° to 8.3°C (12° to 15°F) increase per minute, irrespective of the starting temperature.
