Intelligent Reflective Beam Detector

Installation and Operation Manual The Intelligent Solution

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.

Relative Humidity≤95%, non condensing

10. Monitoring Area: Maximum monitoring area: 14×100＝1400m2

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:

¾Space height is over 40m.

¾It is not roofed.

¾Space height is less than 1.5m.

¾There are a lot of dust, powder or vapor.

I-9105R

Intelligent Reflective Beam Detector

¾It is clean normally, but can be dusty in some special cases.

¾Temperature 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 for 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.

¾There 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:

a) When space height is not over 5m, the detector and reflector

should be mounted on the two facing walls 0.5m from the ceiling, as

shown in Fig. 4.

b) When space height is between 5m and 8m, the detector and

reflector should be mounted on the two facing walls 0.5m to 1m

from the ceiling, as shown in Fig. 5.

c) When space height is more than 8m, the roof is normally

gabled without ceiling, the detector and reflector should be

mounted on the two facing walls about 8m from the floor, ensuring

that the vertical distance between the detector/reflector and top of

the building is not less than 0.5m, as shown in Fig. 6. The distance

should be 7m from the detector to the floor.
