ii) The location of the CIE, or other enclosure, containing the
SPT;
- shall, when installed as part of a new I&HAS; be in an
area provided with 'direct alarm protection'
located where it is not visible to, or readily accessible
by, members of the public.
- should, when retro-fitted to a pre-existing I&HAS; be
in an area provided with 'direct alarm protection'
and be located where it is not visible to, or readily
accessible by, members of the public.
Alarm protection of Site Network Equipment
'Site Network Equipment'
i)
which has a locally or remotely accessible and changeable
function, (e.g. a telephone switchboard or IP router),
together with Alarm Transmission Path (ATP) aerials* and
network access termination points, shall be located in an
area provided with 'direct alarm protection'
Other 'Site Network Equipment'
ii)
intermediate junction boxes, should be provided with
'direct alarm protection'
* Where an ATP aerial cannot be located in an area readily
provided with 'direct alarm protection'
recommended minimum signal strength for adequate
performance, it may be installed elsewhere (preferably indoors
but otherwise outdoors), subject to positioning it where its
discovery and/or ready access by intruders is considered
unlikely.
Connections between the SPT and Site Network
b)
Equipment
i) Any radio based ATP shall have a cable connection
between the SPT and the required aerial, with all cable
termination points, including those at any intermediate
connections, using termination components (or housings)
that protect against cable removal without the use of a
tool.
ii) Any landline based ATP shall have a cable connection
between the SPT and the first suitable alarm transmission
network termination point within the premises. This shall
be made in one continuous run and use termination
components (or housings) that protect against cable
removal without the use of a tool.
The connection to the alarm transmission network shall be
made in such a manner that where non-alarm related
apparatus/services are also connected to that network, they do
not prevent, or interfere with, the correct operation of the ATS.
Notes
a)
The phrase 'direct alarm protection' shall mean that
sufficient detection devices are installed to ensure that,
when the I&HAS is set, access to the protected equipment
results in a full (e.g. a 'confirmed') alarm condition. Where
an I&HAS uses a time delayed entry/exit route as part of
the facility for unsetting, detection devices programmed to
act as entry/exit route detection shall not be regarded as
providing 'direct protection'.
b)
The phrase 'Site Network Equipment' shall be regarded as
all equipment installed within the alarmed premises
through which signals from the SPT to the alarm
transmission network beyond the perimeter of the
premises are transmitted. For example, non-alarm

and still achieve the
dedicated (shared use) IP routers, telephone
switchboards/Private Automatic Branch Exchanges
(PABX), network access termination points, ATP aerials
and communication network junction boxes/switches.
ARC/ATS message holding
Where the Alarm Receiving Centre (ARC) and/or ATS provider
offers, or requests use of, a facility to block the receipt of, or
a)
hold information relating to, ATS fault notification signals or
messages pending receipt of further alarm information (e.g.
pending the designation of a confirmed alarm as per BS 8243),
agreement to such an action shall be confirmed in writing by
the customer (end user); with the relevant notification stating
that this action is compatible with the risk assessment and/or
the requirements of any interested party, for example an
insurer.
In such cases the installer shall make suitable arrangements,
which shall be confirmed in writing, for the customer to be
alerted to any such ATS fault notification signals/messages
when their alarm system is next unset, or after a period of 96
hours, whichever is the sooner.
Customer (end user) Information
Installers shall advise the customer:
i) of any potential for normal ATS functions, including normal
or 'stepped up' checking of ATS availability (e.g. by
sending test signals), which could interfere with, or prevent
use of, any non-alarm related apparatus/services
connected to a telephone line shared with the ATS. In
such cases customers should be recommended to
consider use of an ex-directory 'In Coming Calls Barred'
(ICCB) telephone line dedicated to ATS use.
ii) of the adverse effect on reliable operation of their intruder
alarm system that may result where 'Site Network
Equipment'
- could have its correct operation/settings locally or
remotely accessed and changed/disabled, for
example a non-alarm dedicated (shared use) IP
router. In such cases customers should be
recommended to consider protection against
unauthorised access by the use of an access
password (not the factory default) and, if their
equipment has wireless connectivity having the
wireless network Access Point Name (APN) hidden.
- would cease to work in the event of loss of mains
power; for example a Private Automatic Branch
Exchange (PABX) or non-alarm dedicated (shared
use) IP Router. In such cases customers should be
recommended to consider protecting the power
supply against disconnection by use of an unswitched
fused spur connection or by having such equipment or
its power supply connections located in an area/room
to which unauthorised access is restricted.
iii) of the adverse effect on reliable operation of their intruder
alarm system that may result from cessation of any
communication service(s) necessary for correct operation
of the ATS; for example telephony services such as 'three
way calling' (Star Services) or access to internet services
(via an ISP). In such cases customers should be
recommended to take steps to ensure that availability of
these services is maintained at all times when their alarm
system is likely to be in use.
