Hi forum ... this hurting my brain today.
If standard response sprinklers are installed in a given space - a
retail tenant,
can QR extended heads be used in a subsequent addition. The two areas
will have the same ceiling
and I want to use extended heads in the addition because of intense
surface strip lighting.
Also, does anyone know if an extended head can be used in a 12 x 12
spacing @ 7 psi if
the listing starts at 14 x 14?
Thanks for any info!
Vince
