4: Split Alarm And Silencing - Honeywell HPFF12 Instruction Manual

Programmable Features
The DIP switch 7 setting of a 2 hour delay of TB2 TROUBLE contacts can be used for remote station, central station, or proprietary pro-
tected premises reporting, in compliance with UL 864 9th Edition.
NOTE: Always use supervised monitoring of TB2's AC FAIL and TROUBLE contacts and to set DIP switch 7 for a delay for UL 864 9th
Edition compliance.
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.
