Description
The oil/water alarm unit in a wall mounting housing triggers visual and
audible alarms in the event of accumulations of liquids which can be caused
by tank leaks, backflow, flooding, etc. ÖWWG 3 consists of a control unit
with visual/audible alarm,Test and Acknowledge buttons as well as a flexible
PTC thermistor probe. The probe is mounted at the lowest point of the
area to be monitored. The alarm is triggered when the probe comes into
contact with liquid. The audible alarm can be muted with the Acknowledge
button. The visual alarm remains active until the leak has been fixed.
The Test button allows you to simulate an alarm condition in order to
perform a function check. The self-monitoring probe triggers an alarm if
it is damaged. The voltage-free relay contact is provided for connection
of additional alarm equipment (such as additional alarm unit ZAG 01).
ÖWWG 3 is suitable for panel mounting with a mounting frame. A sealing
kit (IP 54) is available for rough application conditions. Alarm units can
be integrated into your existing building automation systems at lug the
wireless module into the interface (PCB of the device). The Gateway in
conjunction with additional RIELS products with wireless technology allow
you to configure a whole range of fully customisable, extensible features for
the protection of plants and buildings.
