Functionality

"DOKA - a" is installed in closed space for continuous detection of fires accompanied by the appearance of smoke, operating with a built-in battery.

"Doka - a" provides:

automatic fire detection

fire notification independently or as part of the AFA system *

activation of any external device for fire warning

continuous self-testing of working capacity

battery charge control

* AFA is an autonomous fire alarm system consisting of a group of 2 to 40 DOKA-a detectors connected by a two-wire line. In addition, an external fire warning device (siren, or Smart Home system, or GSM alarm system, or other automatic equipment) can be connected to any "DOKA-a", for which a signal can be generated by closing a normally open line.

Назначение

"ДОКА - а" устанавливается в закрытых помещениях для непрерывного обнаружения возгораний, сопровождающихся появлением дыма, работая от встроенного элемента питания.

Variants of "DOKA - a" application

Variant 1

"DOKA - a" independently detects smoke and notifies about the fire

Variant 2

"Doka - a" is combined into AFA. One goes into the "Fire" state and for the others generates a signal
"Fire alert"

Variant 3

The annunciator (siren) with its own power supply is connected to "DOKA - a". When switching to the "Fire" state, the detector closes the siren feed circuit.

Variant 4

"DOKA - a" is connected to a normally open loop of any automatic equipment that has a fire warning function. When switching to the "Fire" state, the detector closes the loop.

You can mix options 2, 3, 4 in any combination. The siren and / or automatic equipment can be connected to any of the detectors in the AFA system.

The advantages of "Doka - a"

The advantages of "Doka - a"

qw-1

Dust-resistant, due to the measuring chamber which is hidden under the body and protected by a thin mesh. The dust settles in special compartments, without reaching the camera.

qw2

The body is made with vertical and horizontal smoke outlets, which allows you to catch currents in any direction and quickly respond to the first signs of fire.

icon_2

Operates in an extended temperature range: from –10 ° С to + 50 ° С

icon_4

Has reliable contacts for connecting wires
