Remote Supply With Resettable and Nonresettable Power
Applications
Notes: The following notes apply to Figure 5.3 on page 32.
1. When the HPF24S power supply is in an inactive state (control module not active), a trouble
on the power supply will result in an open circuit condition on the control module output
circuit (monitored by End-of-Line Resistor across Terminals 5 & 6). As an alternative, the
trouble contacts at TB5 of the power supply can also be used for independent trouble
monitoring.
2. Do not loop wires under screw terminals. Break wires to maintain proper supervision.
3. An End-of-Line Resistor must be installed between terminals 5 & 6 for control module wiring
supervision (the ELR value is dependent on the module employed) and across terminals 7 & 8
for FACP NAC wiring supervision (the ELR value is dependent on the NAC).
4. For a list of compatible devices, refer to the Device Compatibility Document.
5.4 Remote Supply With Resettable and Nonresettable Power
The HPF24S can be used as a remote stand-alone power supply to provide power to any devices
that require filtered, resettable or nonresettable power. The HPF24S6 can provide up to 4 amps of
continuous current and the HPF24S8 can provide up to 6 amps of continuous current. The power
supply must be set for Split Alarm mode. Output circuits 1 & 2 are configured as resettable power
outputs by connecting the resettable power from an FACP to Control Input 1 Terminals 3(+) & 4(-)
on TB4 of the HPF24S. Output circuits 3 & 4 are configured as nonresettable power outputs by
connecting jumpers between the auxiliary 24 VDC output on TB4 to the Control Input 2 terminals
on TB4 [Terminals 9(+) to 7(+) and 1(-) to 8(-)].
NOTE:
All four outputs can be configured as resettable or all four can be configured as
nonresettable by setting the power supply for General Alarm and then connecting a resettable
power source to Control Input 1 or a nonresettable power source, such as the Aux. Power output
of the
HPF24S
, to Control Input 1
