I Overview

I-9105R Intelligent Reflective Beam detector (the detector) is an
addressable reflective infrared beam smoke detector that has two
signal output ways: loop output and contact output. When the detector is
connected with GST fire alarm control panel directly, state information
will be transmitted through loop between the detector and the control
panel. The detector can be programmed by GST programmer. Code
range is within 1~242. When the detector is not connected with the
control panel, fire and fault information can be transmitted by contacts.
The detector must be used together with a reflector. The number of
reflector(s) to be used (one or four) depends on the distance from the
detector.

With excellent built-in microprocessor, the detector has strong ability of
analysis and judgment. The detector can carry out system adjustment,
compensation of variation of ambient data, and judgment of fire and
fault through fixed algorithm. With new and reasonable design,
esthetical pleasing, flexible judgment and alignment method, it’s easy to
install and adjust. The sensitivity of the detector can be set through
hand held programmer in field, decreasing the demand for cleanliness
of field conditions, and enlarging application areas.

The detector is applicable to historical buildings, warehouses, large
storages, shopping malls, leisure centers, exhibition halls, hotel lobbies,
printing houses, clothing factories, museums and prisons, as well as
places where slight smoke particles.

3. Operation Principle
The detector and reflector are placed oppositely . The detector includes
emitting part and receiving part. Infrared beam of certain intensity sent
out from the emitting part is reflected by the right-angle prisms of the
reflector, and then received by the receiving part of the detector. The
receiving part simultaneously collects and amplifies the returned
infrared beam, analyze and judge the collected signals through its
microprocessor. When the detector is in normal monitoring state, the
intensity of infrared beam received by the receiving part is steady at a
certain level. When smoke particles enter the detecting area, the
intensity of infrared light received by the receiving part falls owing to
light scattering. When the smoke particles reach a certain density, and
the intensity of infrared light received by the receiving part is reduced
below the preset threshold value, the detector alarms fire, illuminates
red LED. And fire output contact is closed. If connected with GST
control panel, the fire signal will be passed to the panel through loop.
Operation principle is shown in Fig. 3.

V Mounting and Wiring

1. Ambient Conditions for Installation

The detector works on light obscuration principle. Avoid any fixed or
moving obscuration in its optical pathway when installing.

The wall for mounting either the detector or the reflector should be firm
and smooth. The detector is mounted vertical to the wall. The wall may
seem to be smooth, but corrugated or uneven, or may be changed by
the environment (in rainy season or in winter) and the installer should
ensure the detector not affected by these factors. If the detector is
installed on sustaining rack similar to metal tube, make sure the
sustaining rack fixed firmly.

Not Fit For Locations where:

¾ Space height is over 40m.
¾ It is not roofed.
¾ Space height is less than 1.5m.
¾ There are a lot of dust, powder or vapor.

¾ It is clean normally, but can be dusty in some special cases.
¾ Temperature is high. Note: Temperature at top part of a

workshop with transparent roof may be over 50℃ when
there is sunshine.

¾ There is no access for maintenance.
¾ The Mounting wall or fitting is greatly affected by mechanical

vibration.

¾ There are fixed or moving objects within 1m from the

detector’s optical pathway.

¾ There is strong magnetic field.

2. Mounting Height and Position

The mounting height of the detector and reflector should be most
accessible by smoke into beam zone. The following recommendations
are for reference:

reflected, please consider mounting a sunshade over the
detector’s optical pathway or contact our field application engineer
for a solution.

3. Mounting

1) Setting Length of Optical Pathway

Before installation, you need to set the length of optical pathway
first by setting device type of the detector . The detector can work at
two levels of length. When mounting distance between the
detector and the reflector is not less than 40m (but not more
than100m), the detector type should be set at “52” (factory default).
When the mounting distance between the detector and the
reflector is less than 40m (but more than 8m), the detector type
should be set at “51”. Refer to Section VIII Operation for detailed
setting methods.

2) Mounting the detector

3) Mounting the Reflector: The reflector is mounted opposite

the detector but in line with it. When the distance between the
detector and the reflector is more than 8m (less than or equal
to 40m), one reflector is enough. When the distance is more
than 40m (less or equal to 100m), four reflectors are needed.
Two ∅6 plastic expansion bolts are needed to fix a single
reflector. Mounting size is shown in Fig.11a. If four reflectors

finished to ensure the detector work stably.

VI Commission

1. Steps
a） Take off the protective membrane carefully on the surface of the

reflector and the detector. Do not scratch or contaminate their
surfaces.

b） Remove the detector’s top cover, and connect to 24VDC power. Two

minutes later, put the magnet of commission tool close to the reed
switch (around the red LED) of detector’s interface board. There may
be two cases with the LEDs:

（1）Green LED flashes.
（2）Green LED illuminates continuously.

Take away the commission tool.

c） If green LED flashes, it means the received light is quite weak (the

slower the flashing frequency , the weaker the received light signal is).
Tune the adjusting wheel and rotary rack on the detector to align the
light beam until green LED is lit continuously, showing that the light
received by the detector is strong. Then stop regulating and enter

14

15

step d).
If green LED illuminates continuously, it means the received light is

quite strong, you can go straight to step d).

Note: Observe the detector’s optical p ath way carefully to ensure
that the received light signal is reflected by the reflector rather
than by obscurations like wall, ceiling, or pillar. If uncertain,
verify by covering the reflector with opaque objects.

d） Put on the top cover gently, and screw the two bolts on the cover.
e） The green LED illuminates continuously. Put the magnet of

commission tool close to the zone where marked

○

M until yellow LED

illuminates constantly, then remove the commission tool quickly and
make sure there is no obscuration on the optical pathway. About 5
seconds later , the detector begins to adjust automatically. Y ellow LED
flashing means weak light, green LED flashing means strong light. If
red LED, yellow LED and green LED flash alternately , this means the
detector failed to adjust automatically and cannot enter normal
monitoring state. Please open the detector’s top cover and do
adjustment from step b). If yellow LED and green LED illuminate no
more, and red LED flashes periodically, this means the detector is at
the best position and has entered normal monitoring state. The
commission is finished.

2. Fire alarm test

After the detector has been in normal monitoring state for 20
seconds, cover the receiving window and emitting window with the
IR Light Filter (please use the part for fire alarm test), the detector
should report fire alarm in 30 seconds and red LED should turn on.

3. Fault test

Cover the receiving or emitting window of the detector quickly with
the IR Light Filter (please use the part for commission) to obscure
the optical pathway. Yellow LED of the detector should be turned on.
Taking off the filter immediately, yellow LED of the detector should be

16

turned off.

4. Failed Detector

During testing, repair failing detectors according to directions in
Section IX Troubleshooting and X Maintenance, and test again, if
they fail again, return them to factory for repair.

VII Cautions

1. Power up only after all devices are well connected.

2. Adjust the detector after installation and maintenance.

3. Under adjusting condition, both the detector loop and fault output

contact transmit fault signal.

4. The detector base should be fixed directly on solid wall or frame

that will not be deformed by vibration. Any deformable material
such as paperboard, plastic board, foam board or thin wood board
should not be placed between the base and the wall or the bracket.

VIII Operation

5. Other Functions

1） Automatic Compensation of Light

When dust exists in the working environment of the detector, the
emitting window, receiving window and reflector will be covered
with dust, which will affect normal operation. In order to solve the
problem, we designed the function of automatic compensation of
light. When there is dust on windows, the detector can judge the
amount of dust, and compensate the received signal through
internal program and circuit to ensure the detector can continue to
work normally. The detector gives fault signal when dust on the
lens and reflector surface reaches a certain level and light
compensation reaches the limit for the detector to work normally.

2） Self-diagnosis on Optical Signal

The detector has functions of checking emitting, receiving and
amplifying circuit. When there is fault with these three parts of
circuit during operation, the detector will generate fault
information.

1. If the detector gives fault signal after working for a long time, first
check whether the detector is damaged or not, and make sure that it
is fixed to the wall or other fittings. Then check whether it is the
accumulating dust and positional excursion, causing compensation
fault, then consider other types of fault.

2. If emitting window, receiving window and reflector surface are found
contaminated, clean them with soft cloth and alcohol (avoid
scraping). Never use water or other chemicals. Commission the
detector again after cleaning and make it in monitoring state.

3. The detector is fire protection product, whose operation must be
well recorded by the personnel on duty and shift.

4. Personnel on duty should be familiar with the functions and

Appendix 1 Warnings

Limitations of Smoke Detector

The smoke detector is designed for triggering and initiating emergency
fire equipments, but it only functions when matching with other
equipments. Installation of this smoke detector must conform to
electrical codes and standards in your country.

The smoke detector cannot work without power . It cannot work if power
is cut off for any reason.

The smoke detector may not sense fire that where smoke cannot reach
it, such as in chimneys, in walls, on roofs, or on the other side of closed
doors.

The detector also may not sense a fire on another level of a building.
Therefore, detectors should be placed on every level of a building.

All types of smoke detector have limitations. Because fires develop in
different ways and are often unpredictable in their growth, it is
impossible to predict which type of detector will provide the earliest
warning. No types of smoke detector can sense every kind of fire every
time. Generally speaking, detectors may not warn you about fires
caused by insufficient safety measures, violent explosions, leaking gas,
improper storage of flammable materials like diluents and other safety
hazards, arson or children playing with fire. The alarm of a smoke
detector used in high velocity environment will be delayed due to
dilution of smoke by frequent and fast airflow. What’ s more, the smoke
detector has to be maintained frequently because there will be more
dust contamination.

The smoke detector cannot last forever. In order to keep the detector
working in good condition, please maintain the equipment continuously
according to recommendations from manufacturers and relative nation

I-9105R
Intelligent Reflective Beam Detector
Installation and Operation Manual The Intelligent Solution

23

codes and laws. Take specific maintenance measures on the basis of
different environments.

The smoke detector contains electronic parts. Even though it’s made to
last for a long period of time, any of these parts could fail at any time.
Therefore, test your smoke detector at least every half-year according
to national codes or laws. Any smoke detectors, fire alarm devices or
any other components of the system must be repaired or replaced as
long as they fail.
