b)

 

remove

 

two

 

screws

 

that

 

fix

 

the

 

labyrinth

 

and

 

take

 

the

 

labyrinth

 

out;

 

c)

 

perform

 

the

 

necessary

 

cleaning.

 

A

 

delicate

 

brush

 

as

 

well

 

as

 

vacuum

 

cleaner

 

are

 

recommended

 

for

 

cleaning.

 

Compressed

 

air

 

can

 

be

 

possibly

 

used.

 

It

 

is

 

permitted

 

to

 

wash

 

the

 

labyrinth

 

with

 

warm

 

water

 

with

 

addition

 

of

 

washing

up

 

liquid.

 

No

 

damp

 

patches

 

should

 

remain

 

on

 

the

 

labyrinth

 

internal

 

surfaces

 

after

 

washing

 

and

 

drying.

  

After

 

cleaning

 

the

 

detector

 

should

 

be

 

assembled,

 

its

 

functioning

 

should

 

be

 

tested

 

using

 

a

 

smoke

 

imitator

 

or

 

smoke

 

generator

 

and

 

installed

 

again

 

into

 

the

 

detection

 

line.

  

In

 

this

 

order

 

to

 

assemble

 

the

 

detector,

 

it

 

is

 

necessary

 

to:

  

a)

 

fasten

 

the

  

labyrinth

 

with

 

two

 

screws;

 

b)

 

place

 

the

 

basket

 

in

 

the

 

reverse

 

position

 

as

 

that

 

shown

 

in

 

the

 

figure;

 

c)

 

insert

 

the

 

net

 

into

 

the

 

basket

 

paying

 

attention

 

to

 

its

 

positioning

 

 

alignment

 

with

 

the

 

juts;

 

d)

 

insert

 

the

 

cover

 

into

 

the

 

basket

 

so

 

that

 

the

 

illuminating

 

diode

 

is

 

placed

   

a

 

little

 

to

 

the

 

right

 

in

 

relation

 

to

 

the

 

glass;

 

e)

 

turn

 

the

 

cover

 

to

 

the

 

left.

 

 

Note

 

 

In

 

case

 

the

 

cleaning

 

does

 

not

 

produce

 

the

 

required

 

result,

 

it

 

is

 

necessary

 

to

 

send

 

the

 

detector

 

to

 

the

 

manufacturer

 

for

 

repair.

DETECTOR

 

INSTALLATION

 

The

 

DOR

4046

 

detectors

 

are

 

installed

 

(height,

 

arrangement)

 

according

 

to

 

the

 

guidelines

 

settled

 

by

 

the

 

Scientific

 

and

 

Research

 

Centre

 

for

 

Fire

 

Protection.

 

They

 

are

 

mounted

 

in

 

premises

 

where

 

the

 

working

 

equipment

 

or

 

stored

 

materials

 

may

 

emit

 

visible

 

smoke

 

when

 

a

 

fire

 

occurs.

 

In

 

case

 

it

 

is

 

difficult

 

to

 

determine

 

the

 

most

 

probable

 

fire

 

factor

 

(smoke

 

type)

 

that

 

is

 

likely

 

to

 

occur

 

in

 

the

 

first

 

fire

 

development

 

phase,

 

special

 

tests

 

should

 

be

 

carried

 

out

 

(at

 

a

 

designing

 

stage)

 

using

 

various

 

type

 

detectors

 

or

 

mixed

 

protection

 

(e.

 

g.

 

with

 

optical

 

and

 

ionisation

 

detectors)

 

should

 

be

 

applied.

  

The

 

detectors

 

are

 

intended

 

to

 

operate

 

in

 

loops,

 

in

 

loops

 

with

 

straight

 

branches

 

or

 

in

 

radial

 

detection

of

Note

 

 

The

in

atmosphere

 

that
