Hey guys,
I’m having trouble determining whether Fenwal model PSD-7157 and CPD-7501 detectors are compatible with a Fenwal 3220 control unit when installed with model 6SB bases.
The installation manuals for each detector reference the 70-63 compatibility sheet for listed control units. I honestly just can’t figure out how to read the thing: http://www.suppression.com/uploads/pdf/fire-alarm-conventional-panels-732/fenwal-control-panel---smoke-and-heat-detector-compatibilty-chart-f-70-63_print.pdf . Are all of the detectors listed at the top compatible with all panels listed? Or am I missing an identification number somewhere that lets you tell the difference?
Any help would be greatly appreciated!
EDIT: Disregard the mention of 6SB bases. Some boxes were mislabeled, I was able to locate proper 2-Wire bases for these detectors.
