NOTE:
The above master to slave wiring configuration
DOES NOT comply with NFPA 99 wiring guide-
lines for two required master panels.
If digital display modules are used for a master
alarm, EACH master panel must be directly con-
nected to a sensor module for each pressure/vac-
uum service.
Additional panels, if desired, may be connected
as indicated above.
NOTE:
Field wiring cable shields must be grounded at
only one end, inside alarm panel back box. Refer
to page 39 for details.
