Fire-Lite FCPS Series Field Charger/Power Supply - Manual (Page 22)

22 FCPS-24FS Series Instruction Manual — P/N 51883-L8:J1 8/30/13
Programming Options Programmable Features Description
vide synchronization timing pulses from a dedicated sync output connector. Connect the FCPS
sync input terminals to the FACP sync output connector instead of the FACP NAC.
Note that the Synchronization Type configured by DIP switches 1 and 2 must be set to the same type
as the signal being fed to the Sync Input circuit in the event that Selective Silence is employed.
Important! In Slave Mode, if the Input is active, but no signal is present on the Sync Input circuit,
the power supply will turn the NACs on steady until a sync signal appears. The NACs will turn off
when the Input becomes inactive.
Also in Slave Mode, if the Input is active and the Sync Input is suddenly lost (FCPS or wiring fail-
ure), there will be a three second period when NAC outputs are indeterminate. After this three sec-
ond period, the power supply will turn the NACs on steady until the Input becomes inactive.
3.2.3 AC Fail Delay/Aux. Trouble Relay Function
The AC Fail Delay feature provides the option to delay generation of a trouble signal upon the loss
of AC power. In addition, the operation of the Aux. Trouble Relay is altered.
• DIP switch 4 set to the ON position will delay the generation of an AC Loss/brownout trouble
signal for 2 hours. In addition, the Aux. Trouble Relay will immediately respond to all trouble
conditions on the power supply.
• DIP switch 4 set to the OFF position will allow the FCPS to generate a trouble signal
immediately on the loss of AC power. In addition, the Aux. Trouble Relay will respond only
to AC power fail/brownout conditions.
Refer to “Supervision of FCPS-24FS Faults” on page 25, for operation of internal NAC trouble
relay in response to AC loss.
3.2.4 Input/Output Function
DIP switches 5 and 6 are used to determine the Input Control circuits that will activate the four out-
put circuits and the function of the output circuits. For example, to configure a General Alarm
operation in which Input Control Circuit #1 activates all four output NACs, DIP switches 5 and 6
are both set to the OFF position. In this configuration, the Sync Input circuit is ignored if the power
supply is set as a Master but will be monitored if the supply is set as a Slave. In addition, if the
Auxiliary Power output is set as a resettable output, the circuit connected to Control Input Circuit
#2 will control the auxiliary power reset function.
The following table details the four possible input/output configurations:
DIP Switch 5 DIP Switch 6 Input/Output Function
OFF OFF General Alarm
• FCPS configured as Master (switch 3 OFF), NAC Outputs 1 through 4 1 are controlled by
Control Input #1; Sync Input is ignored.
• FCPS configured as Slave (switch 3 ON), NAC Outputs 1 through 4 2 are controlled by
Control Input #1; Sync Input is monitored 2 .
• Resettable or nonresettable Auxiliary Power Output is available from TB4 Terminals 9 & 10.
Control Input #2 determines if reset will occur (must go from On to Off for a minimum 6
second reset to occur).
OFF ON Split Alarm
• FCPS configured as Master (switch 3 OFF), NAC Outputs 1 & 2 are controlled by Control
Input #1 and Outputs 3 & 4 1 are controlled by Control Input #2; Sync Input is ignored.
• FCPS configured as Slave 3 (switch 3 ON), NAC Outputs 1 & 2 are controlled by Control
Input #1 and Outputs 3 & 4 1 are controlled by Control Input #2; Sync Input is monitored 2 .
• Only nonresettable Auxiliary Power is available from TB4 Terminals 9 & 10.
