OAS-WI

Product Description

The OAS-WI water ingress detection system comprises a centralised cabinet housing the main processor, various electrical components, Ex1-W00 intrinsically safe diode safety barriers and an indication panel located in the bridge. The sensor is a type WI-22 level detector based on conductivity principle, which connects to the alarm module containing the safety barriers, in the central cabinet. Up to 12 off pairs of sensors can be connected to the system. The alarm is processed by a common alarm-processing unit CU2-C01 and relayed to the OAS-5 remote alarm panel. The sensor can be terminated in a flanged deck assembly or fitted on a flanged protection tube located inside lower stool on sloping plates. The alarm panel provides unique audible pre-alarm at 0.5 M and main alarm at 2 M conditions as well as system alarms and channel override facilities.
