DETECTOR INTRODUCTION
2.1.
Open the package
!
If the detector was in conditions of negative temperatures, keep it for at least 4 hours
at the temperature of the heated room.
2.2.
Disconnect the detector from base and check the package contents:
* –
1 pcs. per 5 detectors allowed
**
–
upon agreement with the purchaser it is allowed not to deliver in the package
2.3.
Familiarize yourself with the design of the detector
џ
compare the serial number and date of manufacture on the case with the records in
your datasheet;
џ
make sure that there are no visible mechanical damage (cracks, chips, dents);
џ
make sure that the warranty seal is intact.
2.4.
Connect the battery and place it in the battery compartment in the
detector housing
2.5.
Press and hold the "Test" button for at least 2 seconds
The detector must switch to the "Fire" state. Make sure that the volume of the
sound signal is loud enough and that it sounds without audible defects. The light
should flash simultaneously with the sound signal.
!
The "Fire" state sound signal is very loud. While pressing the “Test” button, keep
the detector at arm's length.
2.6.
After releasing the "Test" button, the detector must return to the
"Standby Mode" state
Make sure that the light indicator flashes once every 20-25 seconds after
switching to the "Standby Mode" state.
3.
DESIGN AND OPERATING PRINCIPLE
The detector is an automatic electronic device with an optical sensor that signals
the appearance of smoke at the place of its installation.
The optical density of the medium inside the sensing chamber is analysed by
measuring the level of reflected IR radiation from the surface of the smoke particles
and then processing the received signal.
The response time of the detector to smoke depends on the fire conditions and
the properties of the burning materials.
If there is no smoke in the measuring chamber, the detector will be in the
"Standby Mode" state. There should be periodic single flashes of the light indicator
in red and no sound signals at all.
When smoke appears in the detector's sensing chamber, the detector goes into the "Fire" state.
The alarm is triggered by switching on the light and sound signals on the detector itself, issuing a
"Fire Alert" signal for other "DOKA - a" detectors as part of the AFA system and closing the
normally open built-in "Fire" relay. The detector remains in the "Fire" state until the end of
exposure to smoke and then switches to the "Standby Mode" state.
The detector is powered autonomously by a replaceable battery with a nominal
voltage of 9 volts. The detector provides electrical and mechanical protection
against incorrectly connected battery polarity. When the battery is low, the detector
generates a periodic light and sound signal.
The detector has a system for self-testing the performance of the optoelectronic
unit and the battery charge level.
If there is a complete loss of performance (or complete discharge of the battery),
any indication will be absent.
Forced testing of the "Fire" state is performed using the "Test" button.
The detector housing is made of impact resistant ABS plastic and forms a
protective shell.
A chamber with compartments is structurally made in the front part of the
housing to keep dust from getting inside the optical-electronic system.
The detector is shielded from static electricity and electromagnetic interference.
The base is used to install and connect the detector. The detector is
connected to the base by means of a detachable connection without using
any special tools.
The detector is connected to external circuits via the
multi-connector according to the diagram (see section 5.2).
The multi-connector has four numbered contacts:
џ
"General" (4) and "NO" (3)
- serve to transmit a fire signal by closing the NO
circuit for any external device (siren, Smart Home, GSM alarm system, etc.);
џ
"General" (4) and "AFA" (2)
- serve to group "DOKA-a" detectors (AFA
system);
џ
(1)
-
is a technological contact
,
any connections are prohibited.

INDICATION AND FUNCTIONS
"Standby Mode" state:
џ
The light indicator flashes every 20-25 seconds - the detector works properly
.
џ
The light indicator flashes every 20-25 seconds simultaneously with a sound
signal - the detector is working correctly, but the battery is low to 7.5 V. The
power supply element has to be replaced!
"Fault" state:
џ
A short sound signal every 20-25 seconds at the same time as the light
indicator - optoelectronic unit is faulty. The detector must be taken in for
repair!
"Fire" state:
џ
Intermittent (approximately 3 times per second) sound and light signals
.
џ
Closing of normally open relay contacts "Fire" ("NO" and "General")
.
џ
Appearance of voltage on the "General" and "AFA" contacts as a "Fire
Alert" signal for other detectors in the AFA system.
"Alert" state (only for detectors in the AFA system):
џ
Intermittent (approximately 3 times per second) sound signal
.
џ
Closing of normally open relay contacts "Fire" ("NO" and "General").
"Test" state:
џ
Similar to indication and functions in the "Fire" state.

NSTALLATION AND CONNECTION
5.1.
Selection of the detector installation location
It is not advisable to install the detector in areas where gases, vapours and aerosols
that can cause corrosion and false detectors are released.
Placement of the detector in premises must be carried out strictly in accordance with
the requirements of the design documentation (if any).
If you have purchased and are installing the detector on your own initiative, the
following recommendations must be taken into account:
џ
th
e main task of the detector is to sound an alarm when you do not control
the fire situation in your home. Therefore, install the detectors first in or near
bedrooms on the side of the most likely fire source (e.g. kitchen);
џ
the most preferable location of the detector on the ceiling in the middle of the room;
џ
it is prohibited to install the detector closer than 1 metre from ventilation openings;
џ
install the detector as far away as possible from sources of electromagnetic
interference (electrical wiring, fluorescent lamps, etc.) and infrared radiation
(heaters);
џ
prevent water from entering or flowing on the side of the base;
џ
it is permissible to install the detector on the wall.
