Amps Posted March 12, 2009 Posted March 12, 2009 Could somebody please clear this up for me please, is it ok to four wire detectors on a grade 2 system or must it be e.o.l.
A-G Posted March 12, 2009 Posted March 12, 2009 either / both comply . . . PM me for access to the SSAIB members discussion area.
antinode Posted March 12, 2009 Posted March 12, 2009 I believe it is OK to use double pole on Grade 1 and 2 systems. We use FSL for Grade 2 and 3. Trade Member

Yes, you're right .... the only way we do eol/fsl is the fsl way, so I forgot about the single resistor methods of eol . . . PM me for access to the SSAIB members discussion area.
