Programmable Features Description

ON
ON
1 If Door Closer function is selected (switch 8 ON), Output 4 does not function as an NAC, therefore sync input is
ignored for Output 4.
2 If no synchronization is selected by switches 1 & 2, the Sync Input is ignored.
3 When using Split Alarm with power supply configured for Slave Mode, System Sensor cannot be used (use
System Sensor with Master Mode only).
4 Selective Silence allows the silencing of the sounder portion of a horn/strobe combination device without turning
off the strobe.
Auxiliary Power Control
The 24 VDC Auxiliary power from TB4 Terminals 9(+) & 10(-) can be resettable or nonresettable
power only when the power supply is configured for General Alarm operation. For all other con-
figurations, the auxiliary power output is only nonresettable.
In the General Alarm configuration, the Auxiliary power output can be made resettable by applying
a steady signal to Control Input 2 (positive 12 to 24 VDC on TB4 Terminal 7 and common on Ter-
minal 8). Temporarily removing the voltage or reversing the polarity will cause the Auxiliary
power output to reset for 6 seconds.
3.2.5 Charger Enable/Disable
The HPF24S battery charger can be disabled to accommodate an external battery charger. Setting
DIP switch 7 to the default setting of OFF will enable the battery charger. Setting DIP switch 7 to
the ON position will disable the charger. It should only be disabled if an external battery charger is
being used for the HPF24S.
3.2.6 Door Closers
Output Circuit #4 can be configured as an NAC or door closer circuit. Setting DIP switch 8 to the
OFF position will configure Output Circuit #4 as an NAC. Setting DIP switch 8 to the ON position
will configure only Output Circuit #4 as a door closer circuit which will provide a steady 24 VDC
to door holders until an alarm or AC fail condition removes the power following a 10 second delay.
HPF24S Series Power Supplies — P/N 52751:E1 4/14/2011
Split Temporal
• HPF24S configured as Master (switch 3 OFF), Control Input #1 controls NAC Outputs 1 & 2
and Control Input #2 controls Outputs 3 & 4
without sync; Sync Input is ignored.
• HPF24S configured as Slave (switch 3 ON), Control Input #1 controls NAC Outputs 1 & 2
and Control Input #2 controls Outputs 3 & 4
without sync; Sync Input is monitored for Outputs 1 & 2
• Only nonresettable Auxiliary Power is available from TB4 Terminals 9 & 10.
4
Selective Silence
• HPF24S configured as Master (switch 3 OFF), NAC Outputs 1 through 4
Control Input #1; Sync Input is ignored.
• Control Input #2 determines when Selective Silence for all outputs will occur.
• Only nonresettable Auxiliary Power is available from TB4 Terminals 9 & 10
