Alarm Strobe/Horn
The Rig Monitor has a red alarm strobe light/horn installed in the top conduit hub. The
Rig Monitor retains its NEMA 4 rating with the strobe installed. Strobe operation is
controlled by the Alarm 1 relay contacts. The relay action settings can be changed in
Configuration Mode.
Magnetic Wand
The magnetic wand is a short plastic rod with a magnet in one end. It is used to actuate
the magnetic control switches on the control PCB while the junction box cover is still
installed so that non-intrusive calibration can be performed.
