Introduction
FastSense
25
incorporates a patented ‘artificial intelligence‘ known as
ClassiFire
® , which allows the detector
to configure itself to optimum sensitivity, alarm thresholds and minimum nuisance alarms for any environment.
ClassiFire
intelligence also monitors the detector chamber and dust separator for contamination, continually
adjusting the appropriate operating parameters to counteract the negative effects of such contamination. The
Ampac range of detectors is unique in being able to provide a consistent level of protection in a very wide
range of environments by continuously making minor adjustments to sensitivity.
The Ampac range of detectors has proven its worth many times by detecting ‘difficult
-to-
detect’ slow

electrica
l overload incipient fires in ‘difficult’ environments
.
This handbook gives information likely to be needed for most installations, but for more detailed information on
subjects such as Fresh Air Referencing, please refer to the complete Technical Manual or System Design Guide.
This equipment is Class 111 as defined in EN60950 or AS/NZS 3260:93 (i.e., this equipment is designed to
operate from Safety Extra Low Voltages and does not generate any hazardous voltages).
Warning
This detector must only be installed by
FastSense
25
accredited installers.
This detector has an IP 50 rating and is not suitable for installation where it may be exposed to falling or
spraying of any form of liquid or corrosive gases or chemical fumes.
The performance of the system is dependant upon the pipe network design. Any extension or modification to
the designed network may alter the performance of the system. The correct operation of any such changes
must be verified with the use of the
PipeCalculator
.
PipeCalculator
is available from your Local Ampac
Customer Service Office.
Conduit entries to the
FastSense
25
unit are designed for 27mm outer diameter conduit. When using 25mm
outer diameter conduit ensure that the 27mm to 25mm adaptors provided with the unit are fitted.
As this equipment is part of a fire detection system, it should be supplied from an approved power supply
conforming to EN54-4, AS4428 Part 5 or to NZ4512.
This symbol appears on the main board of the unit and indicates that the board contain static
sensitive components. Suitable anti-static precautions must be taken when handling the board, eg. for fuse
replacement.
LASER CLASS 1
PRODUCT
This label is located on the laser chamber at the bottom right of the open detector and
signifies that the unit is a Class 1 Laser product as specified in IEC 60825-1 and AS2211. The unit incorporates
a Class 3B embedded laser which must not be removed from the detector as retinal damage may result if the
laser beam enters the eye.
This symbol indicates the Safety Earth studs (see sections 1.3 and 1.4). These are for grounding cable
screens etc. and should not be connected to ØV or signal earth.
Ampac has taken every care to ensure that
FastSense
25
is as simple to install as possible but in case of
difficulty, please contact our Local Customer Service Office to ensure trouble free installation and operation.
