4.5 Remote Power Supply - Resettable and Nonresettable
The FCPS may be used as a remote stand-alone power supply to provide up to an
additional 4.0 amps of power to any devices that require filtered, regulated, resettable
or nonresettable power. A monitor module may be used to monitor the trouble contact
of the FCPS. If the FCPS enters a trouble condition the normally closed contact will
open. A resettable output is created by tying the resettable output from the FACP to one
or both of the power supply inputs. A nonresettable output is created by cutting an on
board resistor (R175 for Output 2, R176 for Output 4). For addressable panel
applications, use a monitor module to sense the trouble status of the remote power
supply via the trouble relay contact. Cut JP2, R63 and D31 for this application.

Notes:
1) Outputs 2 and 4 are also resettable 24 VDC power in this example. To make Output 2
nonresettable power, cut R175. To make Output 4 nonresettable, cut R176.
2) The specific ELR required to be installed on the FCPS trouble monitoring contacts at TB3-
3 and TB3-5 is dependent on the particular model of monitor module employed to supervise
the FCPS. Fire-Lite models M300 and M301 require a 47K ELR. Fire-Lite model M302
requires a 3.9K ELR.
3) Do not loop wires under screw terminals. Break wires to maintain proper supervision.
4) If an addressable M302 Monitor Module is employed to monitor the trouble contacts of the
remote power supply, the module must be supplied with separate 24 VDC power. This power
is required so that the module may supervise the connection to the trouble contacts of the
power supply.
5) One of the FCPS nonresettable power outputs (TB4) can be used to supply 24 VDC to M302
terminals 3 and 4 or a separate power source can be used.
The auxiliary power output of
the FCPS power supply (TB3 Terminals 8 & 9) should not be used for this purpose.
6) For a list of compatible devices, refer to Fire-Lite Device Compatibility Document.
7) It may be necessary to use an EOL relay on outputs that are normally activated for proper
supervision.

Circuit #2
Resettable outputs deliver a negative polarity
voltage of up to -5 VDC during reset. In the unlikely
case that this negative voltage causes a problem
resetting certain models of 4-wire smoke detectors,
use TB-4 terminals 3 (+) and 2 (-) for Output #1 and
terminals 9 (+) and 8 (-) for Output #3.
