Notes on system
installation
The power-up of the control panel and
commissioning of the system is done by
the Servicing organisation.
Installation requirements
It is recommended that the installer follow the general
requirements of BS5839:Part 1:2002, which is the code of
practice relating to fire detection and alarm systems for buildings.
The installer must follow the relevant parts of BS7671 : 1992
Requirements for Electrical installations, 17th edition of IEE wiring
regulations if installation is in the United Kingdom, UK.
Second fix installation
To prevent the possibility of damage or dirt degrading the
performance or appearance of the products, the installation of
the panel should be delayed until all major building work in the
area is complete.
"The installation of all outstanding parts and
panel the panel power up is usually carried out during
system commissioning.
Fixture and fittings
It is the installer's responsibility to provide adequate fixtures and
fittings for the type of construction surface onto which a product
is to be mounted, whilst utilising the fixing points on the product.
As an aid to this decision, the weight and overall size of each full
assembly together with implications on cable entries and routing
should be taken into consideration.
"All these procedures assume that the cable,
gland, steel box (BESA box) and other related
accessories are provided by the installer.
As fitted drawings
The installer should acquire site specific information from the
interested parties, for details on the location of products for
installation. The acquired information together with this guide and
the relevant standards should be used to assist the work.
Each product assembly can be identified from its package label.
The contents of all packages should be checked for any
discrepancies.
Cable type and routing
Appropriate attention must be given to ensure the correct cable
type is installed in accordance with 'as fitted drawings', site
specific information and recommendations of BS5839 Part 1 :
2002. The cables must be installed using cable manufacturers
recommended fixing and accessories.
Fire sensor cover
Each fire sensor may be supplied with a plastic dust cover. The
cover must be fitted to prevent dust and dirt from the building
work contaminating the fire sensor.
Earth continuity
All earth connection points should be clean to provide a good
electrical conductivity path. To maintain the earth
continuity: all earth leads and fittings provided should be
installed. The loop cable screen must be continued through
each system device on the loop circuit, whether the earth is
connected to the device or not.
"Do not use any part of building structure for
earthing.
Some of the system products having metal enclosure with zinc
coating around the cable termination points, the coating
provides a good electrical conductivity path for cable earth
termination. The zinc coating on metal enclosures should not be
damaged. Any damage will expose bare metal, which can
corrode and make a poor earth connection.
Power supply
The power to the system is derived from the mains and battery
supplies. Before removal of the electronic module from the panel
or disconnection of any cable from the board ensure both mains
and battery supplies are disconnected.
Mains supply
Mains supply to any fire alarm control and indicating equipment
must be via an unswitched 5A fused spur unit. A disconnect
device must be provided to disconnect both poles and must have
a minimum gap of 3mm. The disconnect device should be
available as part of the building installation and must be easily
accessible after installation is complete.
&All mains powered equipment must be earthed.
Devices
Always install new devices on the loop circuit. Never use devices
that have been previously installed on the loop circuit of another
system.
Local Manual Call Point
To comply with the requirements of EN54-2 : 1997 a manual call
point must be installed near the control panel. The call point
when activated must be set up to sound all alarms without delay.
"Failure to install and configure a local manual
call point in the manner described above when delays are
set up on the system will result in the panel not
complying to EN54- 2 : 1997.

EN54 information
Optional functions with requirements of this European standard
The Control panel complies with the requirements of EN54 : Part 2 : 1997. In addition to the basic requirements of the standard the
panel conforms to the following optional clauses:
Clause Description
7.8 Output to fire alarm devices
7.11 Delays to action outputs
8.3 Fault signals from point
10 Test condition
System wiring
"
If instructed, the installer may need to terminate as well as connect the cables to the appropriate terminal blocks.
Cable separation
Where the outgoing and return cables of a loop circuit covers more than the equivalent of one zone they must not run together, for
example, either close to the Control Panel or in a service duct. There should be as much physical separation as possible between
the cables and the mechanical protection of the cable should be to a particularly high standard. This is to minimise the risk of
accidental damage to both cables.
Lightning protection
Where a loop cable is mounted to an external wall or between two buildings then consideration should be given to the use of
lightning protection devices.

Requirements of cables
The British Standard BS5839 Part 1 : 2002 Code of practice for
system design, installation, commissioning and maintenance
states the requirements for standard and fire resisting cables in
Clause 26.2 section d and e.
"d) Standard fire resisting cables should meet PH 30
classification when tested in accordance with EN50200 and
maintain circuit integrity if exposed to the following test:
- a sample of the cable is simultaneously exposed to flame at a
temperature of 830ºC- 0+40ºC and mechanical shock for 15min,
followed by simultaneous exposure to water spray and
mechanical shock for a further 15min.
e) Enhanced fire resisting cables should meet the PH120
classification when tested in accordance with EN 50200 and
maintain circuit integrity if exposed to the following test:
- a single sample of the cable is simultaneously exposed to flame
at a temperature of 930ºC - 0+40ºC and mechanical shock for a
period of 60min, followed by simultaneous exposure to water
spray and mechanical shock for a further 60min."
"The cables listed in this manual are those that
have been tested for EMC compliance with the system
products.
Loop Cable usage
"There is a maximum limit of 1Km loop cable
usage allowed per loop circuit. This maximum limit is the
sum of the cable used on main loop circuit, spurs off
main loop circuit, plus cable runs to all input / output
lines off loop powered interface units installed on the
loop.
There is a further maximum limit of 100m cable run
allowed per input/output line off loop powered interface
unit.
Mains Supply cable
The mains supply cable must be a standard fire resisting type
and should meet PH30 classification, such as any of the standard
and enhanced cables listed above.
Repeat indicator to Control panel cable
A maximum of 1Km cable distance is allowed between Control
Panel and Repeat indicator panel
¨Belden No. 9842 EIA RS485 Applications, O/A
Beldfoil® Braid having two twisted pairs
Loop cable
A loop cable carries both data and power, therefore its selection
is important. Note the following:
¨In countries where the European EMC directive is in
force, only EMC Compliant cables are to be used.
¨The loop cable usage must not exceed 1Km. This
includes the cable used on main loop and spur circuits.
¨Single pair cable must be used. It is NOT permissible
to run mixed loops or outgoing and return pairs in a
multi core cable, due to inadequate separation and
possible electrical interference problems.
¨Each core of the loop cable must be 1.5mm2cross
section area.
¨The cable screen must be capable of being earthed at
each system device.
¨Red is the preferred cover sheath for fire applications.
¨The specified loop circuit cables are also suitable for
wiring master alarm, auxiliary relay, input/output lines
and mains supply.

"The cables marked * utilise laminated
aluminium tape with a tinned drain wire for electrostatic
screening. Under certain environmental conditions
galvanic action may take place between the aluminium
and the drain wire. This will severely degrade EMC
performance as the foil to drain wire impedance will
increase. Armoured variants of these can also be used
for wiring a loop circuit.

SenTRI ONE System

Devices per Device loop
"It is important that redundancy is built into the system to accommodate future expansions.
The number of devices on the loop circuit can be limited by the total number of addresses available, the electrical load on the circuit,
the maximum cable length and other geographical considerations.
¨The loop circuit must not cover more than 10,000m2of floor area of a protected site.
¨In total a maximum of 127 devices are allowed on the loop circuit.
¨As a general rule allow 1000 load factor for the loop circuit and only use the 2nd value when calculating the
maximum load factor.
The following table can be used as a rough guide only to determine loop load.
"For a precise battery standby value use the Battery Standby Calculator. The Battery Standby Calculator
should be used during system design stage using the Commissioning tool.
