When used with a DS9431 , power is
connected to the option bus power terminals
(RA or RB = +, BA or BB = -). Connection to
other (24V) sources will damage the DS7432.
To control panel 12VDC power terminals:
DS7400, terminals 7 and 8, Fig. 4
DS9400, terminals RA and BA, Fig. 5
To DS7430, DS7436 or DS9431 MUX
BUS Terminals (see Figure 4 or 5)
For UL Listed fire installations, Normally
Open (N/O) contacts must be used.
