DC24V Explosion proof Linear Infrared Beam Smoke and Fire Detector

DC24V Explosion proof Linear Infrared Beam Smoke and Fire Detector

Product Overview

DFTC-HW(K)Explosion proof infrared beam smoke and fire detector(Hereinafter referred to as detector)It is a flameproof reflective linear infrared beam smoke detector. This detector can be equipped with a coded linear beam smoke and fire detector produced by the host manufacturer. The detector must be used in conjunction with a reflector, but one or four reflectors may be used depending on the installation distance between the two. The explosion-proof performance of the detector meets the requirementsGB3836—2000 According to the requirements of the series standards, the inspection unit has passed the inspection and obtained the explosion-proof certificate. Applicable to1 District2 The area contains Class IIATheBTheClevelT1~T6Hazardous locations in explosive gas environments with temperature groups.

DC24V Explosion proof Linear Infrared Beam Smoke and Fire Detector

Performance Characteristics

1. Communication method: non-polar dual bus; And relay output andRS485outputmodbusagreement

2. Equipped with automatic compensation function, it can automatically compensate for the impact caused by factors such as dust and vibration to a certain extent, improving the performance

Reliability of detectors;

3. Easy debugging, with concentric laser module indication, making it easy to find the optical path, and digital display to indicate the reflected light intensity;

4. Sensitivity and distance values can be set on-site through a handheld encoder;

5. PCBFully sealed protection process for the board.

6.Supports both encoding and non encoding application modes.

Product Parameters

5.Indicator lights: Debugging status: Green and yellow indicator lights light up and flash in a specific way;

Normal monitoring status: The red indicator light flashes periodically;

Fire alarm status: The red indicator light is always on, and the yellow indicator light is off;

Fault status: The yellow indicator light is constantly on;

The light path is completely blocked: the detector first reports a fault and lights up the yellow indicator light,20sThe rear detector will report a fire alarm again, and

Turn on the red indicator light and turn off the yellow indicator light.

6. Fire alarm and fault contact output (invalid output terminal when encoding mode):

Fire alarm relay: contact capacity30V/2A, normal wiring terminalHJ1TheHJ2Normally open, closed in case of fire alarm.

Fault relay: contact capacity30V/2A, normal wiring terminalGZ1TheGZ2Normally open, closed in fault state.
