.
4.0 Base POPIT Addresses
Each D278S and D298S has a specific address
determined by setting the seven DIP switches located
on the detector's base. Refer to Figure 4. The base's
address does not depend on the base's location in the
circuit.
Use Table 3 to set the address for the D9112 or D9124
FACP. If adding the base to a previous version FACP,
set Switch 0 to ON and set all other switches to OFF.
