6. Installation
The panel must be installed by suitably qualified
engineers familiar with the installation of fire
detection systems. In addition, it is recommended to
refer to the following information:
Current edition of the IEE wiring regulations.
Current edition of BS5839-1 or the installation
standards for the relevant country.
Any specific site requirements.
Any field device installation instructions.
Any data sheet provided for the installation of
Intrinsically Safe devices.
Notes:
The rating plate, containing essential electrical
information is located inside the panel on the
inside face of the door.
Any mains supply cable should be a minimum
of 1mm
2
copper protected by a 5A fuse and
must include an appropriate lockable double
pole disconnect device as part of the building
installation. This device must have a minimum
contact gap of 3mm.
6.1 Electrical Safety
WARNING:
Read this section completely before
commencing installation.
Prior to commencing installation of the
panel,
ensure
that
adequate
precautions are taken to prevent
damage to the sensitive electronic
components on the PCBs due to
electrostatic discharge. You should discharge any
static electricity you may have accumulated by
touching a convenient earthed object such as an
unpainted copper radiator pipe. You should repeat
the process at regular intervals during the
installation process, especially if you are required to
walk over carpets.
The panel must be located in a clean, dry
position, which is not subject to shock or
vibration and at least 2 metres away from pager
systems or any other radio transmitting
equipment. The operating temperature range is -
5ºC to 40ºC; maximum humidity is 95%.
Precept EN Exp 4 and Precept EN Exp 5 Output
Expansion panels must be located immediately
adjacent to the fire alarm panel.
IMPORTANT NOTES ON BATTERIES [when
fitted]:
DANGER:
Batteries are electrically live at
all times, take great care never to short
circuit the battery terminals.
WARNING:
Batteries are often heavy; take great
care when lifting and transporting batteries. For
weights above 24 kilos, lifting aids should be used.
DANGER:
Do NOT attempt to remove the
battery lid or tamper with the internal
workings of the battery. Electrolyte is a highly
corrosive substance, and presents significant
danger to yourself and to anything else it touches.
In case of accidental skin or eye contact, flush the
affected area with plenty of clean, fresh water and
seek immediate medical attention.
Valve Regulated Lead Acid (VRLA) batteries are
“low maintenance”, requiring no electrolyte top-
up or measurement of specific gravity.
WARNING:
Only clean the battery case
with a cloth that has been soaked or
dampened with distilled water. Do not use
organic solvents (such as petrol, paint
thinner, benzene or mineral spirits) or
other materials that can substantially weaken the
case. Do not use a dry cloth as this will generate
static electricity, which in turn may lead to an
explosion.
WARNING:
Avoid operating temperatures outside
the range of -15
C/5
F to +50°C/122°F for
float/standby applications.
The recommended normal operating temperature is
20°C.
HIGH TEMPERATURE will reduce battery service
life. In extreme cases this can cause Thermal
Runaway, resulting in high oxygen/hydrogen gas
production and battery swelling. Batteries are
irrecoverable from this condition and should be
replaced.
LOW TEMPERATURE will prolong battery life but
reduce output capacity.
DANGER:
Do not incinerate batteries. If
placed in a fire, the batteries may rupture,
with the potential to release hazardous
gases and electrolyte. VRLA batteries contain
substances harmful to the environment.
Exhausted batteries must be recycled. Return them
to the battery manufacturer or take them to your
Council waste disposal site for appropriate disposal.
ELECTRICAL SAFETY:
The volt-free relay contacts provided within the
panel must not be used to directly switch any
voltage that exceeds 50VAC or 75VDC. (Please
also refer to relay rating data).
This equipment requires a 230V AC supply. [See
Rating Plate inside equipment. See also section
3. ] All installation work should be carried out in
accordance with the recommendations of
BS5839 Part 1 and the current edition of the IEE
regulations by suitably qualified and trained
personnel.
