Applications
Controlling Three NACs and One Door Holder With One Input
4. An End-of-Line Resistor must be installed between TB4, Terminals 5 & 6 for control module
wiring supervision (the ELR value is dependent on the module employed).
5. Supervise the power wiring between the HPF24S auxiliary 24 VDC output on TB4, Terminals
9 & 10 with an EOL relay (P/N: A77-716B)
6. For a list of compatible devices, refer to the

IMPORTANT!
When the power supply is programmed for both
Selective Silence
and
Slave
Mode
, TB4 Terminal 7 (IN+) must be jumpered to Terminal 9 (AUX+) and Terminal 8 (IN-)
must be jumpered to Terminal 10 (AUX-). The FACP will control the Selective Silence feature
with this configuration.
If the terminals are not jumpered as indicated, the horn portion of the horn/strobes will be
silenced at all times.
5.2 Controlling Three NACs and One Door Holder With One
Input
In this application, the power supply has been set as a master with synchronized outputs. All four
HPF24S output circuits, three NACs and one door holder, can be controlled from one input such as
an addressable control module as illustrated in Figure 5.2. The control module can be powered
from the HPF24S auxiliary 24 VDC power output (TB4, Terminals 9 & 10).
