installation, commissioning and maintenance of I&HAS installed in buildings. Requirements for I&HAS are specified
in EN 50131‑1:2006.
The recommendations of this Technical Specification (TS) also apply to IAS and HAS
when these systems are installed independently.
When an I&HAS does not include functions relating to the detection of intruders, the
requirements relating to intrusion detection do not apply.
When an I&HAS does not include functions relating to hold-up, the requirements relating
to hold-up do not apply.
NOTE Unless otherwise stated the abbreviation I&HAS is intended to also mean IAS and HAS.
These application guidelines are intended to assist those responsible for establishing
an I&HAS to ascertain the appropriate design of I&HAS both in terms of the extent
of the supervision required and in determining the grade of system performance necessary
to provide the degree of supervision considered appropriate.
These application guidelines are also intended to assist those responsible for selecting
equipment appropriate to both the level of performance required and the environmental
conditions in which the equipment will be required to operate.
These application guidelines are relevant to all classes and grades of I&HAS of any
size and complexity. These application guidelines should be read in conjunction with
EN 50131‑1:2006.
NOTE It has been assumed in the drafting of these application guidelines that the execution
of its provisions will be entrusted to appropriately qualified and experienced persons.

or use an I&HAS.
