MAAP Ground Fault Troubleshooting Guide Rev C.wpd Page 7 of 7
Additional SLC LOOP Troubleshooting: Disconnect the SLC loop from the port. Measure
the resistance of each leg to earth ground. There must be greater than 500K Ohms from earth
ground to either loop conductor.
a. If there is less than 500K Ohms from earth ground to one loop conductor, divide the
circuit in half and re-measure until the resistive source is located.
b. Any conventional detector must have greater than 500K Ohms between earth
ground and either line of the input to the mini module.
c. If no ground fault occurs, then re-connect the next circuit.
d. Continue until all of the main panel circuits have been re-connected. If no ground
fault occurs contact Product Support at Monaco Enterprises for assistance.
