36、e with the National Electrical Code, NFPA 70. A gas detector and/or sensor and/or vapor detector, as covered by these requirements, consists of an assembly of electrical components coupled with a sensing means inside a chamber, or by separate components to detect toxic and/or combustible gases or va
37、pors. The detector includes provision for the connection to a source of power and signaling circuits. 1.2 These requirements cover the following types of detectors: a) Detectors intended for monitoring the environment and detectors intended for open area protection and for connection to a compatible
38、 power supply or control unit for operation as part of gas detection or emergency signaling systems; b) Detectors intended solely for control of ventilation or shut off devices such as fans or control valves; c) Detectors intended for both the above applications; d) Sensors and sensing circuits inte
39、nded for use with or in gas detectors, alarms or gas detection circuits within fuel cell systems; e) Portable gas detectors; f) Multi-gas gas detectors; g) Multi-gas sensors and h) Equipment intended for use in hazardous locations. Note, the equipment must comply with the applicable hazardous locati
40、on requirements prior to evaluation to UL 2075. 1.3 These requirements also cover all remote accessories that are intended to be connected to a gas or vapor detector and/or sensor. 1.4 This standard does not cover the following: a) Control units to which the detectors are intended to be connected th
41、at are covered by the Standard for Control Units for Fire-Protective Signaling Systems, UL 864; b) Control units to which the detectors are intended to be connected that are covered by the Standard for General Purpose Signaling Devices and Systems, UL 2017; c) Self-contained single and multiple stat
42、ion carbon monoxide alarms or residential combustible gas detectors, not intended for connection to a system control unit, that are covered by the Standard for Single and Multiple Station Carbon Monoxide Alarms, UL 2034 or Residential Gas Detectors, UL 1484; d) Automatic ammable vapor sensor systems
43、 and components covered by the Standard for Automatic Flammable Vapor Sensor Systems and Components, Z21.94/CSA 6.3.

44、ese requirements will additionally need to ensure that inuencing factors not addressed in this standard for the end product installation, such as mechanical movement, eld placement of conductive material, and product damage, will not affect the system for insulation coordination or performance opera
45、tion. Examples are the deformation of the enclosure, movement of the ttings for conduit or armored cable, or the improper installation of eld wiring. 2 General 2.1 Components 2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply with the requirements for
46、that component. 2.1.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall
47、 be used in accordance with its rating established for the intended conditions of use. 2.1.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not excee
48、ding specied limits, and shall be used only under those specic conditions. 2.2 Units of measurement 2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.3 Undated references 2.3.1 Any undated reference to a code or standard
49、appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard.
