ISO 7240-10:2012 pdf download – Fire detection and alarm systems —Part 10: Point-type flame detectors.
5.7 On-site sensitivity adjustment
If there is provision for on-site sensitivity adjustment of the detector, then:
a) for all settings at which the manufacturer claims compliance, the detector shall comply with the requirements of this part of ISO 7240 and shall achieve a classification Corresponding to that marked on the detector for that setting;
b) for each setting in a), access to the adjustment means shall be possible only by the use of a code or special tool or by removing the detector from its base or mounting;
C) any setting or settings at which the manufacturer does not claim compliance with this part of ISO 7240 shall only be accessible by the use of a code or special tool, and it shall be dearly marked on the detector or in the associated data that if these setting or settings are used, the detector does not comply with this part of ISO 7240.
NOTE These adluatments can be carried out on the detector or on me control and indicating equipment.
5.8 Ingress protectIon (IP) — Optional function
The IP category (i.e. IP rating) of the detector shall be specified by the manufacturer, No requirement shall apply to type A flame detectors Type B flame detectors shall comply with rating 1P54C of IEC 60529 (see 6.18),
5.9 MarkIng
5.9.1 Each detector shall be dearty marked with, or supplied with, the following information:
a) reference to this part of ISO 7240, i.e. ISO 7240-10:2012;
b) name or trademark of the manufacturer or supplier:
c) model designation (type or number):
d) classification of the detector, e.g. class 1 (where the detector is ciassified as class 4. irnlicate class 4 aixJ
the distance as determined by;
e) IP rating (if applicable).
f) mark(s) or code(s). e.g. a serial number or batch code, by which the manufacturer can identify, at least, the date or batch and place of manufacture and the version number(s) of any software contained within the detector;
g) wiring terminal designations;
h) angle of reception as determined in 6.4:
i) operating wavelength band(s), e.g. UV. lR.
5.9.2 For detachable detectors, the detector head shall be marked with at least a), b), c), d), e), f), h) and i) from 5.9.1, and the base shall be marked with at least C), i.e. its own model designation, and g).
5.9.3 Where any marking on the device uses symbols or abbreviations not in common use, these shall be explained in the data supplied with the device,
5.9.4 The marking shall be visible during installation of the detector and shall be accessible during maintenance.
5.9.5 The markings shall not be placed on screws or other easily removable parts.
5.10 Data
5.10.1 Detectors shall either be supplied with sufficient technical, installation and maintenance data to enable their correct installation and operation or, if all of these data are not supplied with each detector, reference to the appropriate data sheet shall be given on. or with, each detector.
5.10.2 To enable correct operation of the detectors, these data should describe the requirements for the correct processing of the signals from the detector. This may be in the forni of a full technical specification of these signals, a reference to the appropriate signalling protocol or a reference to suitable types of control and indicating equipment, etc.
5.10.3 Installation and maintenance data shall include reference to an fri situ test method to ensure that detectors operate correctly when installed.
NOTE Additional information can be required by organizations certifying that detectors produced by a manufacturer conform to the requirements of this part of ISO 7240.
5.11 Requirements for software-controlled detectors
5.11.1 General
For detectors that rely on software control, the requirements of 5.11.2, 511.3 and 5.11,4 shall be met in order to fulfil the requirements of this part of ISO 7240.
5.11.2 Software documentation The manufacturer shall submit documentation that gives an overview of the software design. This documentation shall be in sufficient detail for the design to be inspected for compliance with this part of ISO 7240 and shall include at least the following:
a) functional description of the main program flow (e.g. as a flow diagram or structogram). including a bnef
description of
1) the modules and the functions that they perform.
2) the way in which the modules interact
3) the overall hierarchy of the program.
4) the way in which the software interacts with the hardware of the detector,
5) the way in which the modules are called. including any interrupt processing;
b) description of those areas of memory used for each purpose (e.g. the program, site-specific data and running data):
c) designation by which the software and its version can be uniquely identified.
