Point-type temperature-sensitive fire detector
Introduction
Point-type temperature-sensitive fire detector
(hereinafter referred to as the detector) uses the sensitivity of the thermal element to temperature to detect the ambient temperature. . This detector adopts modern technology and uses a microprocessor chip and non-volatile memory inside. It has powerful processing functions and accurate and reliable alarms. Temperature sensing parameter analog quantity collection and processing, and internal intelligent model criteria make up for the shortcomings of the traditional alarm mechanism. The structure is reasonably designed and can sensitively sense the temperature changes of the surrounding air.
Main features and technical indicators
◆Wire system: non-polar two-wire bus
◆Encoding method: electronic encoding, simple and convenient operation
◆Reasonable structural design, sensitive to the surrounding air Temperature changes, rounded and beautiful shape
◆Advanced three-proof processing technology, effectively resists erosion from moisture, mildew, salt spray, etc.
◆Working voltage: bus pulse
◆Working current: monitoring current ., Alarm current
◆Using environment: temperature～+℃
,
Relative humidity%
～%
(no condensation)
◆Dimensions: Diameter, height
◆Weight
◆Alarm confirmation light: red
◆Casing material and color: B beige
◆Detector status display
Normal monitoring status: The light flashes periodically. Fire alarm status: The light is always on. Fault status: The light is always off or flashes irregularly
◆Protection area: When the height of the space is less than 1, the protection area of a detector is . The specific parameters should be based on the "Design Specification for Automatic Fire Alarm System B".
Wiring and installation
Wiring requirements: The insulation resistance between lines and between lines and the ground is greater than 1, and the resistance of a single line of the detection bus loop is less than 1.
The two detectors are connected in parallel.
The bus loop of this system adopts a two-wire system, regardless of polarity. There is a conductor piece on the base of the detector with wiring terminals. When wiring, press the two bus lines of a certain circuit to the terminals of the detector base.
After the base is firmly installed, connect the bottom of the detector to Align the base and rotate it clockwise to install the detector on the base.
The detector should be encoded with an electronic encoder before installation.
