Senator II Installation Manual 78910-03NM Issue 2_10/96

Notes to Installer
The manual contains fixing and wiring information to cover the installation
of the Senator II system, both Standalone and Network.
Installation
requirements It is recommended that the installer follows the general requirements of
BS5839:Part 1:1988, which is the code of practice relating to the fire
detection and alarm systems for buildings. The relevant parts of the Institute
of Electrical Engineers Wiring Regulations 16th edition must also be
followed.
Second fix
installation To prevent the possibility of damage or dirt degrading the performance or
appearance of the Senator II products, the installation of second fix items
should be delayed until all major building work in the area is complete (e.g.
clearing and sweeping).
Fixture and
fittings It is the installers responsibility to provide adequate fixtures and fittings for
the type of construction surface onto which a product is to be installed,
whilst utilising the fixing points on the respective 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.
NOTE: All these procedures assume that the cable, glands, steel boxes
(BESA boxes) and other related accessories are provided by the installer.
Location 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.
Fire sensor
covers Each fire sensor may be supplied with a plastic dust cover. If supplied then
the dust cover must be fitted to prevent dust and dirt from the building
work from contaminating the sensor.

Senator II Installation Manual

Parts for later
installation All unused parts should be retained in their respective container for safe
keeping until required.
NOTE: The installation of all outstanding parts is usually carried out
during Commissioning of the System.
Loop earth
continuity To maintain earth continuity on a loop, the loop cable screen must be
connected through each system device on the loop, whether the earth is
connected to a device or not
NOTE: The network cable screen is earthed at one end only.
Mains supply Mains supply to fire alarm control and indicating equipment must be via an
unswitched fused spur unit.
The fused spur isolator cover should be red and marked:
FIRE ALARM - DO NOT SWITCH OFF
Each of the fire alarm equipments’ fused spur units must be fed from a
dedicated switch or protective device at the local mains supply distribution
board.
Mains and
battery supply
connections
The mains and battery supply cables must be installed to the stage to
facilitate the power up for commissioning.
WARNING: Where mains cable are to remain disconnected,
their tail ends must be insulated to prevent dangerous
conditions arising in the event of accidental switching On of
the mains supply
Cable
termination
and connection
Terminate each cable at the entry point to the enclosure, using the cable
manufacturer’s recommended techniques.
Where the cable is required to be connected, ensure it is secure to the
respective terminal.
Where the cable is not required to be connected, leave 400mm (unless
otherwise specified) tail wire length and mark each core identifying its
final point of connection.
Wiring test CAUTION: DO NOT undertake high voltage insulation tests
WITH THE CABLES CONNECTED to their terminals. Such a
test may damage the electronics circuitry in loop devices and
panels.

EMC Compliance
Installation guidelines for compliance with the
requirements of the Electromagnetic
Compatibility (EMC) Directive
Introduction These guidelines should be followed to meet the requirements of the EMC
directive in force within the European Union, to prevent the reception
and emission of electromagnetic interference into and out of the analogue
addressable fire detection and alarm system.
Products The products covered by these guidelines are listed under EMC compliant
products, see list on the last page of this section.
Code of
practice The installer must follow BS7671 : 1992 Requirements for Electrical
installations, IEE wiring regulations 16th edition if installation is in the United
Kingdom, UK.
Cables The following cables have been tested against EMC directives for use with
with fire detection and alarm applications:
(see also the Cable types part of Installation manual for further information)
For loop circuit, battery connection and master alarm circuit wiring:
•Mineral Insulated Copper Cable (MICC)
•FIRETUF OHLS Cable type: FTZ2E1.5
For network interface to network interface or control panel to
network interface wiring:
•Mineral Insulated Copper Cable1(MICC)
•Belden Cable No 9729 (UL Style 2493)
•Armoured Cable2
By armouring the Belden Cable No 9729 (UL Style 2493)
In the UK, the guidance of BS5839 : Part 1 should also be followed.
EMC Compliance Introduction
78910-03NM Issue 2_10/96

Senator II Installation Manual
1The Mineral Insulated Copper Cable should be used for fire resistant applications.
2The cable manufacturer cannot guarantee the cable specification if it is armoured.

Cable
Separations The cables of the fire detection and alarm system and other systems should
usually be separated by at least 160mm, unless dedicated conduit or ducting
is being used.
In the UK there is additional guidance provided in a document reference
‘Recommended cable separations to achieve electromagnetic compatibility
in buildings’ obtainable from the Electrical Contractors Association.
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, whether the earth is connected to the device or not.
see also Cable termination.
NOTE: Do not use any part of building structure for earthing.
A zinc coating is provided around the termination point, on the inside of an
equipment metal enclosure. This provides a good electrical conductivity
path for cable earth termination.
CAUTION: The zinc coating should not be damaged. Any
damage will expose bare metal, which can corrode and make
poor earth connection.
There are copper fingers fitted to the control and indicating equipment to
fill the gap between enclosure and cover. The fingers provide a shield
against electromagnetic and radio frequency interferences.
CAUTION: It is important to avoid damage to the copper
fingers, as this can re-introduce gap between enclosure and
cover.
Mains Supply The mains supply to mains operated equipment should enter the enclosure
by a dedicated entry, which is the closest to the mains connection points.
Cable
termination Use only cable manufacturers recommendations for cable termination.
The wires between the termination point and terminals should be short and
as straight as possible.
Cable Separations EMC Compliance
Senator II Installation Manual
2-2
78910-03NM Issue 2_10/96

Where Mineral insulated cable (MICC) is being used:
use only galvanised finish junction boxes for installation of alarm and
detection devices
use brass locknut with zinc plated lockwasher to secure gland to the
metal enclosure.
There is no need to use earth tail seals when terminating mineral insulated
cable, providing there is good earth continuity between gland and enclosure.
When using Firetuf cable, the earth drain wire should be fitted to the earth
point nearest the cable entry, with a length not exceeding 50mm.
Board fixing Ensure all board fixing screws are fully tightened, if they have been
removed during installation. The screws maintain an earth continuity path
between the board and its metal enclosure.
