Ventus Basic
1 TO 6 VALVES
The Ventus shut-off valve system facilitates the targeted exclusion of individual wards or functional areas from the central gas supply system. The integrated electronics continuously monitor the pressure in the piping and visually and acoustically trigger the clinical emergency alarm. Additionally, the Ventus system has an intake point that is specific for the type of gas and is protected against unauthorized opening by means of an electronically monitored door with emergency access. Installation is suitable for flush mounting, assembly in dry walls or surface mounting.
Basic version
Door made of sheet steel, powder-coated (RAL 9016), opening > 90° via a lateral hinge.

ELECTRONICS DESIGN
- High level of safety due to redundant microprocessors (if one processor fails, the second processor will assume all functions)
- Clinical operational alarm: Visual (red and green LEDs) and an acoustic signal in the presence of rising or failing pressure (according to DIN EN: ISO 7396-1)
- Reset key for alarm suppression or confirmation (time-dependent alarm repetition every 12 min); test key or a functional test
- The board contains an integrated connection to the central instrumentation and control systems, i.e. possibility of transmitting the alarm via potential-free relay contacts
- Possibility of retrofitting additional electronics or connection to a network system
- RS485 interface for maintenance / service on the electronics
- Display panel for the media designation
HARDWARE DESIGN
For each type of gas, the shut-off unit consists of the following components:
- Zone shut-off valve and manometer
- Physical separation of the pipe system
- Emergency intake option via NIST coupling
- Pressure sensor
