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
Amps Posted March 12, 2009 Author Posted March 12, 2009 Fast answers That sorted then, ta. What's FSL though?
A-G Posted March 12, 2009 Posted March 12, 2009 Fast answers That sorted then, ta.What's FSL though? fully supervised loop ...... same as eol . . . PM me for access to the SSAIB members discussion area.
hpotter Posted March 12, 2009 Posted March 12, 2009 fully supervised loop ...... same as eol Beg to differ, sorry. fsl has an end of line for tamper + another series for alarm. Sorry, grandma, eggs etc....
A-G Posted March 12, 2009 Posted March 12, 2009 Beg to differ, sorry. fsl has an end of line for tamper + another series for alarm.Sorry, grandma, eggs etc.... 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.
