The warning device is used for monitoring of grease
interceptors. Over up to two sensors in the interceptors the
warning device can monitoring following functions:
• Monitoring of fat layer thickness, i. e. when a given
percentage of the max. accumulation capacity for fat has
been reached
• Monitoring of liquid overflow, i. e. when the outlet is blocked

The warning device has a built-in acoustic alarm and LEDs
which show the actual operation mode. Furthermore there are
two independent, potential-free change over contacts for the
connection of central monitoring system or external remote
alarms.
