2x smoke detector VDK-10 + Finder source 12V DC /25 W

The device is intended for shutting down the air handling equipment in the event of combustion emissions.

The device is not a component or part of an electrical fire alarm system.

If it is necessary to use it on a pipe with a circular cross-section, it is necessary to prepare a flat abutment surface on this pipe (or use a blinded T-piece) with holes according to the attached drilling plan - the smoke detector is normally designed for installation on a pipe with a square cross-section.
