Linear fire smoke detector IPDL-D-II/4p version 5

Smoke line fire detector is designed to work as part of fire automation system in all macroclimatic regions (general climatic version).
The detector forms an optical beam passing through the controlled environment outside the detector, and gives a signal of fire in the case of weakening the intensity of the beam by the environment in its smoke.
The detector has built-in heating of optics, which allows its use in unheated rooms with reduced ambient temperature down to minus 40 °C.
The detector can be used in closed and semi-closed rooms where temporary leaks are possible.
The detector consists of a transmitter with a transmitter switching unit and a receiver with a receiver signal processing unit.
The transmitter and the receiver are manufactured in the same design.
