Technical description:
Ventilation smoke switch system for smoke monitoring in ventilation pipes,
consisting of ventilation duct base and
optical smoke switch with smoke detection based on the scattered light principle.
The system is assembled by
Outside. The structure can be done on channels
round and square cross sections
take place.
The alarm relay of the optical smoke switch is with alarm storage
fitted. Resetting one
Alarm is only possible if there is no smoke
and takes place by briefly interrupting the supply voltage. The
Evaluation electronics monitor the smoke measuring part for contamination and malfunctions.
The operating states operation,
Pollution, disruption and alarm become
visually displayed and are from the outside
visible. Through the automatic alarm threshold tracking and the
intelligent evaluation electronics is one
consistent response and
thus a safe operation and a
increased service life guaranteed.
Optionally, the individual operating states can be read out via the RS bus system and sent to higher-level locations
to get redirected.
Thanks to the maintenance-friendly structure
The annual revision can be carried out without tools
take place.
