IS/ISO 7240 : Part 13 : 2020 Fire Detection and Alarm Systems - Part 13 Compatibility Assessment of System Components
NATIONAL FOREWORD
This Indian Standard (Part 13) (First Revision) which is identical to ISO 7240-13 : 2020 'Fire detection and alarm systems - Part 13: Compatibility assessment of system components' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Fire Fighting Sectional Committee and approval of the Civil Engineering Division Council.
This standard was first published in 2021 as IS/ISO 7240-13 : 2005. The first revision of this standard has been undertaken to align it with the latest version of ISO 7240-13 to make pace with the latest international practices.
This Indian Standard is published in various parts. The other parts in this series are:
| Part 2 | Fire detection control and indicating equipment |
| Part 3 | Audible alarm devices |
| Part 4 | Power supply equipment |
| Part 5 | Point-type heat detectors |
| Part 6 | Carbon monoxide fire detectors using electro-chemical cells |
| Part 7 | Point-type smoke detectors using scattered light, transmitted light, or ionization |
| Part 8 | Point-type fire detectors using a carbon monoxide sensor in combination with a heat sensor |
| Part 10 | Point-type flame detectors |
| Part 11 | Manual call points |
| Part 12 | Line type smoke detectors using a transmitted optical beam |
| Part 15 | Point-type fire detectors using smoke heat sensors |
| Part 16 | Sound system control and indicating equipment |
| Part 17 | Transmission path Isolators |
| Part 18 | Input/output devices |
| Part 20 | Aspirating smoke detectors |
| Part 21 | Routing equipment |
| Part 22 | Smoke-detection equipment for ducts |
| Part 23 | Visual alarm devices |
| Part 24 | Fire alarm loudspeakers |
| Part 25 | Components using radio transmission paths |
| Part 27 | Point-type fire detectors using a smoke sensor in combination with carbon monoxide sensor and, optionally, one or more heat sensors |
| Part 29 | Video fire detectors |
| Part 31 | Resettable line-type heat detectors |
A fire detection and alarm system including voice alarm systems combines the functions of detection and alarm in a single system and typically consists of a number of inter-linked components including automatic fire detectors, manual call points and alarm devices. These components are connected to control and indicating equipment by means of one or more transmission paths. All system components, including the control and indicating equipment, are also directly or indirectly connected to a power supply.
A fire protection system and/or building management system, or remote fault and fire alarm monitoring stations that are linked to a fire detection and alarm system, are not considered part of the fire detection and alarm system.
It is necessary for all of the components constituting the fire detection and alarm system to be compatible or connectable and it is necessary that requirements relating to the performance of the overall system be fulfilled.
Differentiation is made between components classified as components Type 1 and other components, classified as components Type 2.
As the possible configurations of fire detection and alarm systems are unlimited, the assessment is only carried out on the configuration(s) declared by the applicant.
This Indian Standard recognizes that it is not practical to assess the compatibility or connect ability of components in all possible configurations. Methods of assessment are specified to reach an acceptable degree of confidence within pre-determined operational and environmental conditions.
In this revision, the following major changes have been incorporated:
a) This revision takes into account new techniques in communication and the availability of new technologies and concepts;
b) This revision is applicable to electrical wires, optical fibre, or radio frequency connections. Previously it was only applicable to electrical wires;
c) Clarification introduced that it is possible to use this standard to establish compatibility with fire protection equipment such as sprinkler flow switches and electrically activated sprinkler heads;
d) Levels (field, control, and management) and a network transmission path for the basis of system configuration introduced;
e) Introduction of Annex A, example of levels used in fire detection and alarm system (FDAS);
f) Introduction of Annex B, classification of functions of the FDAS;
g) Introduction of Annex C, example methodology for theoretical analysis;
h) Introduction of Annex D, software design documentation; and
j) Introduction of Annex E, flowchart for assessment of compatibility/connect ability.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
