Introduction

The installation of a video fire detection system (VFDS) can only be successfully accomplished if the

following conditions are fulfilled:
— materials are of a suitable quality;
— special knowledge in the field of video fire detection (VFD) is implemented;
— skilled personnel carry out the work.

Although the quality of the material can be ensured by adherence to applicable standards and quality

audits, the overall effectiveness of an installation depends widely on the quality of work, the experience

of the designer and installer, and regular service.

This document has been prepared by ISO/TC 21/SC 3. A number of existing national codes and

standards were reviewed during the preparation of this document. As VFD technology is significantly

different from conventional fire detection technology, different considerations need to be addressed and

therefore a document specifying the installation of VFDSs has been developed. While specific to VFDSs,

this document has the same objective of early fire detection as ISO 7240-7. This document specifies the

minimum requirements for fire detection installation using equipment conforming ISO/TS 7240-29.

5 System functionality
5.1 Responsibility

The VFDS shall be subjected to a performance test by a qualified person to verify functionality in the

field as specified by the manufacturer.

NOTE Examples of a qualified person are an installer, designer, commissioning engineer or other responsible

party taking into consideration national guidelines.

The designer shall ensure that propagation of smoke from masked areas to unmasked areas is assured

and detected by the VFDS. Areas that are masked to resolve nuisance alarms shall be covered by a

different fire detector.

The designer shall ensure that equipment conforming to ISO/TS 7240-29 used in the VFDS has been

independently assessed as being compatible with the fire detection control and indicating equipment

(FDCIE), in accordance with ISO 7240-13 when connected to the FDCIE.

Where the requirements of ISO 7240-13 do not directly apply, then it may be used as a guide to prepare

a suitable compatibility assessment procedure.

The designer shall ensure that devices such as motors that may cause vibration or EMI are not in direct

proximity to the VFDS.
5.2 Documentation

The designer shall prepare a list of all components used in the VFDS and identify which components are

compatible.
5.3 Certification

Certification of compatibility of equipment used in the VFDS shall be included in the design

documentation for the VFDS.

Where assessment has not been made by an independent party, the designer shall identify the

components and describe why assessment has not been undertaken.

Where the VFDS interfaces to another system (e.g. building-management system) using voltage free

relay outputs, then self-assessment may be made by the designer and documented accordingly.

Where the VFDS interfaces to another system (e.g. fire alarm system) using a high-level link (e.g. serial

data communication), the designer shall prepare a suitable test plan to ensure reliable interfacing,

including the testing of failure and fault modes. This may be done in conjunction with the equipment

manufacturer.
