Conventional Reflective Beam Detector

Installation and Operation Manual The Intelligent Solution

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.

II Features

(1) Wide operating voltage range, big monitoring areas.

(2) Combination of the emitting and receiving part makes mounting

easy and optical pathway accurate.

(3) Built-in microprocessor enables intelligent judgment of fire

alarm and fault.

(4) The detector can calibrate automatically, which ensures that

one person complete adjustment in short time. It’s also

convenient to operate.

(5) Self-diagnosis function can monitor the inner fault.

(6) Automatic compensation for factors weakening received signals,

such as dust contamination, positional excursion and ageing

transmitter.

(7) It has volt-free output contacts for fire alarm and fault.

(8) Two sensitivity levels can be set in field.

(9) The detector’s optical pathway is designed with strong

anti-interference ability.

(10) SMT processing technology.

(11) Attractive and decent appearance.

certain way. Refer to details in Section VI Commission.

Normal monitoring state: Red LED flashes periodically.

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.

Fire signal has to be cleared by powering up the detector

again.

(8) Operating Environment:

Temperature: -10°C～+50°C

Relative Humidity≤95%, non condensing

(9) Monitoring Area: Maximum monitoring area: 14×100＝1400m2

Maximum width: 14m

(10) Length of Optical Pathway: 8m～100m

(11) Protection Level:

Under common environment, ingress protection rating is IP20.

Under special environment, ingress protection rating is IP66

through glue-seal treatment.

(12) Dimension: length: 206mm width: 95mm thickness: 95mm

(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.

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.

Detector

4.5m

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, refer to 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 more than 0.5m,

refer to Fig. 6. The distance should be 7m from the detector

to the floor.
