The unit can also detect leaks within pipe in pipe systems and bunded tanks using our PPS sensor. Up to 3 sensors can be connected to each zone.

The current alarm status is displayed on a large alpha numeric display. When oil touches one of the sensors the display will flash showing the zone number, an internal audible warning will sound, the common alarm volt free contacts will change state, if fitted, the remote beacon/beacon sounder will start, and if fitted, the SMS text messaging/Email unit will send an alarm message via the mobile network.
