NANO fire system

User responsibility
Your fire alarm system should have been designed,
installed and commissioned to your site specific
requirements and in accordance with the requirements
of BS5839 Part 1. You should have received
instructions about your system during the handover
stage and must make arrangements to ensure the
system is regularly tested and maintained.
It is recommended that the person responsible for
the fire alarm system should ensure the system is
tested and maintained in accordance with the
requirements of BS5839:Part 1 and become familiar
with:
¨the operation of controls and be able to
interpret the indications given at the control
panel
¨keep up to date all documentation associated
with the system.
&Any servicing work on the
system must be carried out by a
suitably trained person, please refer to
your servicing organisation.
Daily
BS 5839:Part 1, states that the system should be
inspected daily to ensure:
¨That a normal indication is given at the
control and indicating equipment.
¨That any previously indicated fault
conditions have received appropriate
attention.
¨All system events are entered into the Log
Book for future reference.
¨That the use of the 'area(s) that are inspected'
has not changed since the system was
designed.
¨That no unsafe practices that could lead to
fire are being undertaken.
Weekly
When testing the system there may be a need to
isolate ancillary outputs and it is important to contact
the alarm receiving centre before and after the weekly
test.
¨A different manual call point of the system
should be tested to ensure the system is
capable of operating under alarm conditions.
¨The operation of the alarm sounders should
be checked, which also reminds the
occupants that there is a fire alarm system
which gives a particular sound output.
"The test should be performed
at a regular time to avoid confusion
between a test and a genuine fire alarm.
The alarm receiving centre must be
contacted before and after the test to
check alarms are received and also to
avoid unwanted alarms.
Quarterly
At quarterly intervals the system should be inspected
and any work necessary should be performed by a
trained maintenance engineer.
"For help with service and
maintenance please refer to your servicing
organisation, see contact details entered
in the log book.
Limitation of false alarm
It is recommended that the person responsible for the
fire alarm system should arrange for suitable
investigation and appropriate action on occasion of
every false alarm. For a system having less than 40
automatic fire detectors installed, an in-depth
investigation should be instigated on occurrence of
two false alarms in any rolling 12 months. For a
system having more than 40 automatic fire detectors
an investigation should be instigated if there has been:
¨one false alarm for every 20 installed
detectors in the system in any rolling
12 months, or
¨two or more false alarm occurrences from a
single device.

Operating instructions

Control and indicating equipment
On occurrence of a fire, fault or disablement event in the protect premises, the event is quickly indicated at the
control panel. The panel controls are password protected and must only be operated by the person responsible
for the fire system.
Control panel
The control panel is the heart of the system. It is normally located near to the main entry or exit point of the
protected premises. The control panel continuously monitor devices that are connected to the device loop. The
device loop cable is routed through the protected premises to cover all areas with both ends of the loop
terminating at the control panel. On the loop cable are installed devices such as fire sensors that constantly
monitor the environment for fire. Alarm devices on the loop provide alert and evacuation alarm to warn
occupants in the protected premises in the event of a fire.
Repeat panels
There may be one or more repeat indicator panels installed in the protected premises to provide secondary
indications of the system events. The repeat indicator panels are usually located near to secondary entry and
exit points of the protected premises.

automatic disablement may be pre-configured for your premises to disable smoke sensors, in areas where
smoke may be present for example during the normal working hours. Also a disablement may be necessary
where building work is being undertaken that could result in a false alarm.
CAUTION: Any changes to
the setting of an automatic
disablement must only be
attempted by a trained
engineer who is
responsible for the fire
alarm system, see contact
details in the Log book.
What must be done? Investigate the reason for the disablement and re-enable if appropriate.
Record the event Where necessary make an entry in the log book of the event for future
reference.
Multiple
