Technical description:
Ventilation smoke switch system for smoke monitoring in potentially explosive areas
Areas of Zone 1 and Zone 2. This
System, consisting of ventilation smoke switch and Ex connection box, is pre-wired for quick and easy
Installation on the ventilation duct.
The system is assembled by
outside and can be used on both channels
both round and square cross-sections. The attachment can
with screws or tension straps
ventilation duct.
The evaluation electronics of the smoke switch monitors the smoke measuring part
for contamination and disruption. The
Operating states: operation, contamination,
Fault and alarm become visual
displayed and are visible from the outside.
Thanks to the automatic alarm threshold tracking and the intelligent
Evaluation electronics is a constant response and therefore
safe operation and increased
Lifespan guaranteed.
Optionally, the individual operating states can be controlled via the integrated RS bus
System read and sent to higher-level
positions are forwarded.
Thanks to the maintenance-friendly structure
The annual revision can be carried out without tools
take place.
