4. Installation
1. Attach EM300 to the wall and mark the two holes on the wall. The connecting line of two
holes must be a horizontal line.
2. Drill the holes according to the marks and screw the wall plugs into the wall.
3. Mount the EM300 to the wall via mounting screws.
4. Cover the mounting screws with screw caps.
5. For leak detection senor, install the probe/cable to the place where liquid may leak. For magn
et switch sensor, install the magnet beside the door/window.
Note: For SLD sensor, please ensure the metal pins of the probe are flat on the floor; for ZLD
sensor, the cable can’t be twined or accumulated together. The probe or cable of water leakage
sensor should be placed in an area of concern where water from a leak would likely accumulate.
