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.
