Wiring & Initial Setup Instructions
1) Install the C2
Protector
controller and remote GASMAX
II monitor. As with all sensors, avoid locations subject to
excessive heat, directed water spray or dust. A splash
guard is recommended on all externally-mounted
sensors.
2) Connect the C2 input terminals to the remote GASMAX
II monitor as shown below. Select a wire gauge that is
sufficient to ensure that there is sufficient voltage
available at the GASMAX II.
3) Make sure the selected C2 channel is set to “ON” (see
the C2 manual, section 2.2.4d).
4) Calibrate the unit to verify proper operation.
