Features

1. The DFE series of features a slim design which combines visual appeal with a high standard of reliability

2. The operating characteristics of all models are a key feature of the product enabling a very cost effective solution for the use of heat detectors. This is further enhanced by the insignificant supervisory current, which enables an unlimited number of detectors to be connected on the same detection wires.

3. With connection to the standard Hochiki range of conventional and addressable bases, the DFE heat detector can be connected or disconnected very easily, allowing simple interchangeability with other types of the Hochiki conventional detection range. Applications The wide operating margin of the DFE fixed temperature heat detector ensures that reliable detection will occur in situations where a fire is characterized by a slow or fast increase in temperature. The DFE range of heat detectors have the widest possible applicability to different types of installations and have been designed to sense heat in a vertical or horizontal position. Consideration should be given to the maximum normal operating temperature before deciding the most appropriate DFE detector for the application. Note : The centre of the metal disk must not be depressed or permanent damage will occur. Specifications Rated Voltage: DC 24V Working Voltage Range: DC 15V - 30V Maximum Switching Current: 300mA Max. Heat Sensing Element Bi-metallic Element Alarming Fixed Temperature (Typical): 54°C~60°C/ 84°C~90°C Storage Temperature Range: -30°C~+50°C/-30°C~+80°C Allowable Ambient Humidity (at 40 C) 95% RH Non-Condensing Dimensions: ø 100mm X 42mm Weight Approximately: 55g Color Off White Applicable Standard: EN-54-Pt5 UL-521 En-54-Pt8 UL-521 Response rade Grade 2 Ordinary Range 1 Intermediate

Thông tin sản phẩm:
FEATURES - Choice of fixed temperature - 135°F or 190°F - UL Listed ceiling spacing of 50' by 50' (2,500 square feet) - Self-Restoring - Heat element protected by a built in guard - Contact Rating of 100 mA - Highly Dependable - Latching LED base available 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. OPERATION The DFE 135/190 fixed temperature heat detector is suited to alarm in the presence of slowly rising temperatures. The construction of this model incorporates an oversized heat collector protected from damage by the built-in, durable plastic guard. The DFE135/190 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.
