Description
Introduction
The ABB SWM4 (Product ID: GHQ4030001R0004) is a resin-encapsulated water detector designed to provide early warning of water ingress in safety and security applications. Operating on a 12 V DC auxiliary voltage with a low power loss of 0.09 W, this device detects moisture accumulation before major water damage occurs. This device is part of our Accessories range.

Engineered for direct operation on the detector circuits of intrusion alarm panels or security terminals, the surface-mounted ABB SWM4 effectively identifies leaks caused by pipe fractures, groundwater, sewage, or faulty appliances such as washing machines and dishwashers.
