I Overview
C-9105R Conventional Reflective Beam Detector (hereinafter called
the detector) is a non-addressable reflective infrared beam smoke
detector, which 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 automatically carry out
system adjustment, compensation of variation of ambient data, and
judgment of fire and fault through fixed algorithm, and indicate these
states by LED and signal output terminals. With new and reasonable
design, attractive appearance, flexible adjustment 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 etc, as well as places where slight smoke particles exist.

Fire: Red LED constantly illuminates,. Fire alarm should be
cleared through powering up again.
Fault: Yellow LED constantly illuminates. 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. 20s later, it alarms fire,
illuminates Red LED and turns off Yellow LED. Note: In this
case, it does not mean there is a fire. After the obscuration
is removed, the detector clears fault signal automatically.

(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, analyzes and judges 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 closes
volt-free fire output contact. 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:
¾Space height is over 40m.
¾It is not roofed.
¾Space height is less than1.5m.
¾There are a lot of dust, powder or vapor.
¾It is clean normally, but can be dusty insome special cases.
¾Where temperature is high. Note: Temperature at top
part of a workshop with transparent roof may be over
50℃when there is sunshine.
¾There is no access to maintenance.
¾The mounting wall or fitting is greatly affected by
mechanical vibration.
¾There are fixed or moving objects within 1m from the
detector’s optical pathway.

positions shown in Fig. 2 (two mounting holes and two wire-in
holes) with glass glue or 703 silica gel after the detector is
fixed and wiring is finished to ensure the detector work stably.
VI Commission
1. Steps:
1) Take off the protective membrane carefully on the surface of the
reflector and of the detector cover. Do not scratch or
contaminate their surfaces.
2) Remove the detector’s top cover, and power up the detector
with 24VDC. 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:
a. Green LED flashes.
b. Green LED illuminates continuously.
Take away the commission tool.
3) 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

16
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 step 4). If Green LED
illuminates continuously, it means the received light is quite
strong, you can go straight to step 4).
Note: Observe the detector’s optical pathway carefully to
ensure that the received light signal is reflected by the
reflector rather than by obstructions like wall, ceiling or
pillar. If uncertain, verify by covering the reflector with
opaque objects.
4) Put on the top cover gently; screw the two bolts on the cover.
5) The green LED illuminates continuously. Put the magnet of
commission tool close to the zone where marked M until Yellow
LED illuminates continuously, then remove the commission tool
quickly and make sure there is no obstruction on the optical
pathway. About 5 seconds later, the detector begins to adjust
automatically. Yellow LED flashing means weak light, Green
LED flashing means strong light. Ten seconds later, 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 again from step 2). 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 20s,
cover the receiving window and emitting window with the IR

HTTP://WWW.HOMBI.RU
C-9105R
Conventional Reflective Beam Detector

17
Light Filter (please use the part for fire alarm test), the detector
should alarm fire in 30s and Red LED should turn on. Fire
volt-free contact is closed. Removing the filter, the detector
should enter normal monitoring state directly without alarming
fire or fault.
3. Fault Test
Cover the receiving or emitting window of the detector quickly
with the IR Light Filter (the part for commission) to obscure the
optical pathway, and Yellow LED of the detector should turn on.
Remove the filter immediately, and Yellow LED should turn off.
4. Failed Detectors
During testing, repair the 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) Adjustment should be made to the detector after installation and
maintenance.
(3) During adjustment, the detector may give fault signal (fault
volt-free output contact is closed), but this will not affect
adjustment.
(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.
