Output Circuit Control DIP Switch Settings
Programming Options
Door Holder
Each output circuit can be configured as a door holder circuit. Setting DIP switch positions according to Table 3.13 will configure the
selected output circuit as a door holder circuit which will provide a steady 24 VDC to door holders until a mapped input activates an alarm or
when an AC fail condition removes the power following a programmable delay. See “AC Loss Door Holder Dropout Timer” on page 25 for
more information.
Synchronizing NACs - Master/Slave Configurations
Each of the HPF-PS power supply outputs can be independently configured for Master or Slave Synchronization by setting DIP switches
according to Table 3.14. Synchronization is a feature that controls the activation of notification appliances in such a way that all devices will
turn on and off at exactly the same time. This is particularly critical when activating strobes which must be synchronized to avoid random
activation and a potential hazard or confusion.
In some installations, it is necessary to synchronize the flash timing of all strobes in the system for ADA compliance. Strobes accomplish
this by monitoring very short timing pulses on the NAC power which are created by an FACP with synchronization capability. If a NAC wire
run from the host FACP or power supply is repurposed as a control circuit to the input of a HPF-PS, the HPF-PS NAC output circuits can
track (follow) the strobe synchronization timing pulses. This maintains the overall system flash timing of the additional strobes attached to
this power supply. Note that strobe synchronization works only with non-coded NACs.
When the output circuit is configured as a
sync generator
(Master Synchronization Configuration), the sync input circuit will only be used to
trigger the output. The power supply is the originator of the strobe synchronization pulse on the NAC output. Refer to Table 3.14 to select the
desired Master Configuration sync type.
When the output circuit is configured as a
sync follower
(Slave Synchronization Configuration), the power supply’s NAC outputs track the
strobe synchronization pulses present at the supply’s Input terminals (based on the settings selected from Table 3.10). The pulses originate
from an upstream FACP or other power supply. Some FACPs provide synchronization timing pulses from a dedicated sync output connector.
Connect the HPF-PS input terminals to the FACP sync output connector instead of the FACP NAC.
If circuits are configured for both Master and Slave Configuration, devices must be installed in different zones or field of view on a circuit
basis.
Master Configuration - Selective Silence
Selective Silence allows the silencing of the sounder portion of a horn/strobe combination device without turning off the strobe. Selective
Silence is only supported while in Master Configuration setting for Amseco, Gentex, System Sensor, and Wheelock. Refer to Table 3.15 to
select the desired Master Configuration, Selective Silence sync type.
Only Command Inputs #1 and #2 are used to control the Selective Silence operation. (Command Input #3 on HPF-PS10 does not support
Selective Silence.) Input #1 is for activating the horn/strobe devices, while Input 2 only controls sounding of the horns. Input #1 must be
active for Input #2 to have any effect on NAC outputs set for Selective Silence. The list below provides additional detail.
•
If only Command Input #1 is active, only the strobes will be activated .
•
If both Command Input #1 and #2 are active, strobes and horns will be activated.
•
If only Command Input #2 is active, NAC outputs will not be activated.
•
If neither Command Input #1 nor #2 is active, NAC outputs will not be activated.

NOTE:
Do not apply synchronization signals to Command Input #1 and 2. Only trigger signals are allowed (i.e. constant 9-32 VDC).
Synchronization signal is internally generated by the system when in Master Configuration.
