Option 1
:
Application of one "DOKA - a" detector as an independent smoke
detection and fire warning device.
Option 2
:
The detectors are grouped (AFA system) by a two-wire line. One of
the detectors switches to the "Fire" state and generates the "Fire Alert" signal for the
other detectors. These detectors switch to the "Alert" state. The maximum number
of "DOKA - a" detectors in the AFA system is 40.
Option 3
:
Install one "DOKA-a" detector and any siren with its own power
source. "DOKA - a" switches to the "Fire" state and closes with the built-in relay
"Fire" minus wire of the siren power supply circuit. The siren must operate at a
voltage of no more than 24 V and consume no more than 300 mA DC.
Option 4:
The "DOKA-a" detector is connected to a normally open loop of any
automation (ACU, Smart Home system, GSM alarm system, etc.), which performs
the function of fire alert. "DOKA - a" switches to "Fire" and closes a normally open
loop. Upon a signal from the loop, the automatics will execute a fire alert. The
voltage in the loop must not exceed 24 V.
You can combine options 2, 3, 4 in any combination. The siren and/or ACU can
be connected to any of the detectors in the AFA system.
!
When connecting, observe the polarity according to the diagrams below.

Options for use
To connect, disconnect the multi-connector as shown in the figure. Connect the
wires as shown in the diagram with a screwdriver.
After connecting insert the multi-connector into the base. Place the wires under the clips.
5.4.
Functionality test
Press and hold the "Test" button until the detector enters the "Fire" state. Then release
the button. If you apply "DOKA - a" in options 2, 3, 4 (or any combination of these), make
sure that all the selected fire alarm modes are executed. After releasing the "Test" button,
the detector will return to the "Standby Mode" after a while.
6.
TRANSPORTATION AND STORAGE
џ
The detectors must be transported in a packed form by any type of transport in
accordance with the rules for the carriage of goods in force for this type of
transport.
џ
Packed detectors during loading and unloading operations and transportation
must not be exposed to sharp shocks and precipitation.
џ
The method of laying and fixing of detectors on the vehicle must exclude their
movement.
џ
Transportation conditions must comply with storage conditions 5 in accordance with GOST 15150.
џ
The detectors must be stored in packages in a heated and ventilated storage areas on
the racks at temperatures from +5 °C to +40 °C and relative humidity of not more
than 80% at 25 °C (storage conditions 1 in accordance with GOST 15150).
7.
MANUFACTURER WARRANTY
џ
The manufacturer guarantees the compliance of the detectors with the
requirements of technical specifications, provided that the consumer meets the
conditions of transportation, storage, installation and operation.
џ
The warranty operation period is 24 months from the date of putting the detector into
operation. The warranty storage period is 12 months from the date of manufacture, provided
that the conditions of Section 6 are met.
џ
Detectors found to be in non-compliance with the requirements of technical
conditions during the warranty period shall be restored at the manufacturer's expense.
џ
Warranties apply to detectors that have no traces of mechanical impact
and the warranty seal has not been damaged.
8.
DISPOSAL CONSIDERATIONS
At the end of its service life, the detector is disposed of in accordance with the
applicable nature protection legislation.
The detector contains no precious metals.
9.
MAINTENANCE
џ
Maintenance of the detector during operation consists of cleaning the detector
components and checking their functionality.
џ
It is recommended to check the functionality of the detector approximately once
a month by triggering the detector with the "Test" button.
џ
In the event of false alarms, an unscheduled dust cleaning of the detector must
be carried out or it must be handed over for repair.
џ
If the detector generates a "Battery Discharge" sound signal, the detector must
be disconnected from the base, the battery replaced and the functionality checked.
Sensing chamber cleaning
џ
Try to blow through the smoke inlet openings for 1 minute with compressed air
on all sides (0.5 ... 3 kg/cm²).
џ
If this does not result in positive results, clean the sensing chamber by
disassembling the detector according to instructions on www.dokasensors.by.
!
After the maintenance and/or removal/installation of the detector, perform its testing.
!
When carrying out maintenance work, it must be ensured that the detectors are
protected from construction materials and dust.

Wire installation
After selecting any of "DOKA-a" applications (except for Option 1), carry out the
wiring installation taking into account the wiring diagram and design of the detector.
Cables and wires of any type and brand with a maximum core cross-sectional area of
1.5 mm² are permitted. Leave the required stock of wires for connection.
5.4.
Base installation
Depending on how the cable is installed, select the holes in the base for the wires
as shown in the drawings and attach them to the installation site. Mark the location
of any two opposite fixing holes. Prepare the holes and fasten the base to a flat
surface (due to the curvature of the surface, the base may be skewed, which may lead
to impossible connections of the detector to the base).
