4: Split Alarm And Silencing - Honeywell HPFF12 Installation And Operation Manual

Programming Options
3.2.4 Split Alarm and Silencing
DIP switch 8, in conjunction with initiating device signal inputs and DIP switches 1 through 6, is
used to program the features of General Alarm, Split Alarm, or Silencing.
• DIP switch 8 set to the ON position will split the NAC outputs to pairs. NAC outputs 1 & 2 are
controlled by Signal Input 1 and NAC outputs 3 & 4 are controlled by Signal Input 2. The
output pairs will be selectively silenced if DIP switches 1 through 6 are set for Pass-through
and FACP input is wired and programmed for that operation.
• DIP switch 8 set to the OFF position and at least one of the NAC outputs are programmed for
synchronization, Signal Input 1 & 2 ON will generate a General Alarm on all four NAC
outputs. General Alarm is activation of both visual strobe and audible horns.
• DIP switch 8 set to the OFF position and at least one of the NAC outputs are programmed for
synchronization, Signal Input 1 ON and Signal Input 1 OFF will silence all four NAC outputs
while keeping visual strobe activation.
NOTE: See Section 5.1 and 5.2 for proper alarm input wiring when DIP switch 8 is programmed
in the OFF position.
