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.

state, and open in fault condition.

5. Angle of Adjusting: -6°～+6°

6. Maximum angular misalignment: ±0.5°

7. Sensitivity Level:

Level 1: 1.61dB
Level 2: 2.31dB

8. Indication of Detector State:

Commission: Green LED and yellow LED are lit or flashed in a
certain way. Refer to details in Section VI Commission.

Normal monitoring state: Red LED flashes periodically.
Fire: Red LED illuminates when the detector reports fire alarm.

Fire output contact is closed. The fire signal can be transmitted to
the control panel through loop and has to be cleared by the control
panel. Power on the detector again to clear the fire signal if GST
control panel is not connected.
Fault: Yellow LED illuminates. Fault output contact is open. The
detector clears the fault signal automatically if the condition
causing the fault disappears.
Optical pathway obscured totally: the detector first gives fault
signal and turns on yellow LED. 15 second later, it reports fire
alarm, and red LED is turned on; fire output contact is closed.
Yellow LED is turned off, fault output contact is closed. Note: In

this case, it does not necessarily mean there is a fire. After
the obscuration is removed, the detector clears the fault
signal automatically. If fault signal turns to fire signal, it has
to be cleared by the control panel or cutting off power.

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.
