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.
Gas Detector
The gas detector senses the target gas and is mounted in a 3/4” conduit hub on the right
bottom side of the M2. A variety of detectors may be used with the M2. Table 2 below lists
the detectors that can be used with the M2.
