To use the compatibility chart, complete the following steps:
- In the top row, locate the control unit's Initiating Device Circuit (IDC) part number.
- In the left column, locate the detector part number and in the third column, select the base part number.
- The intersection of the column and row defines the maximum number of detectors on an IDC monitor zone.
- Do not intermix detectors from different tables on the same IDC. Unless otherwise indicated in the table's notes, you can intermix detectors in the same table without restriction.
