1 Introduction
An aspirati ng smoke detector uses a fan to draw samples of air
from a network of pipes with sampling holes positi oned as if they
were point smoke det ec tors.

systems for buildings
CLASS A, B and C
Technical data: see INF48027 held
by the manufacturer
The detector i nc or por ates a patented artificial intelligence system
called ClassiFire
optimum sensitivity for any environment.
This smoke detect or is defined as Cl ass III in EN 60950. It is
designed to operate f r om S afet y Extra Low Voltages and does not
generate any hazardous voltages.
If this detector is to form part of an approved fire detection system,
its power must be supplied from a certified power supply ( typically
EN 54-4).
In order for the installation to conform to EN 54-20, pipes must
conform at least to EN 61386-1 Class 1131.

, which allows the unit to adjust itself to the
Please note that pri nted circuit boards are stati c sensit ive and must
not be handled without taking proper stati c precautions.
This symbol indicates that the detector i s a Class 1 laser pr oduc t
as defined in IEC 60825-1. This unit incorporat es a Class 3B
embedded laser which m ust not be removed from the detector, as
retinal damage m ay occur if t he beam enters t he ey e.
This symbol indicates that this product m ust NOT be disposed of
with other waste. It i s the user’s responsibility to dispose of this
product by sending it to an approved reprocessing company, or by
returning it to the manufacturer for reprocessing.
NOTE: Every care has been tak en to ensure that the detector is as easy to install as possible by trained
fire Alarm engineers. In case of difficulty, please contact the Hochiki Product Support Department
(contact details are at the front of this manual) in the first instance to ensure trouble free
installation and operation.

2 Outside the Detector
Front Cover Securing Screw: Leave sufficient cl ear ance bel ow the det ec tor to allow
screwdriver access to this screw.
Fire Alarm: Illuminates to indicate that the sm ok e lev el has passed the detector’s Fire 1
threshold, and t he normally open FIRE relay contacts have closed.
Pre Alarm: Illuminates to indicate that the sm ok e lev el has passed the detector’s Pre Alarm
threshold, and t he normally open PRE ALARM relay contacts have closed.
Fault: Illuminates to indicate a Fault conditi on and that the normally closed FAULT relay
contacts have opened. Three additional LEDs i ndic ate the type of fault:
Flow: Illuminates to indicate an airflow fault . This may be due to blocked or broken pipes,
although it can al so occur if, for example, factory warehouse doors are opened on a windy day,
or if industrial air conditioning tur ns on. Another possible cause is that the aspirating fan
connection c able is damaged or disconnected.
Filter: Illuminates to indi c ate t hat t he detector’s air filter needs to be changed.
Head: Illuminates to indicate a problem with the detector laser chamber, as might be caused if
the laser head connect ing cable is damaged or disconnect ed. It can also be caused by certai n
kinds of internal systems faults, which appear in the detector’s Event Log as “process err or s”.
OK: Illuminates to confirm normal oper ation.

NOTE: If the FAULT LED is ill umi nated but none of the additional LEDs are lit , it indicates a problem with
the power supply if its Fault output is connected t o the detect or ’s INP UT terminals and DIL switch
7 is set to OFF (its default position). Alternatively, this can happen if the INPUT terminals are left
open circuit and DIL switch 7 is OFF.
NOTE: During initial setup, the OK LED will flash for 15 mi nutes while the detector learns it s operat ing
environment . Thi s does not i ndic ate a problem with the detector.

3 Inside the Detector
Aspirating Fan Connector Lead: If this lead is broken or not connected, the fan will not turn
and the detector will indicate a FLOW fault.
Main PCB: No user-serviceable parts. The PCB is fixed in plac e with 5 off M3 x 6 screws. The
detector must not be operated with any of the screws missing, as this may cause air leaks and
unreliable oper ation.
DIL switch: Used to configure user-selectable det ector func tions.
Detector Head Ribbon Connect or: If this lead is broken or not connec ted, the detector will
indicate a “Head” Fault .
Detector Head Co ver Plat e: This protects the laser head. The plat e should not be r em ov ed
from the detector.
Detector Head Assembly: No user-serviceable parts. Do not remove this from the detector
due to the risk of exposure t o the laser.
Replaceable Dust Filt er: This simply slides in and out of its mount ing. The filter and its
replacement hav e IN writt en in red on one side, and OUT on the other to indicate correct
orientati on. The part number for ordering spare dust fi lter s i s 30755.
NOTE: As viewed abov e, I N should be on the left and OUT should be on the right, as indi c ated by the
moulded-i n ar r ows next to the filter slot.
