IFS-2600 Fire Indicator Panel Section 4 Installation
DOC-01-009 24
Panel Power Supply
With batteries disconnected and no alarms present, measure voltage across the 0V and MAIN test points
on the 2006 power supply board and, if necessary, adjust the multi-turn potentiometer VR2 until voltage is
26.5V 0.05V (26.45V – 26.55V).
Current limiting is fixed and field adjustment is not possible.
AC Input 30 VAC +10% - 15%
Output Current 3.0 AMPS
Output Voltage 26.5 VDC
Current Limit 3.0 AMPS
Output Ripple 50 mV
Battery Charger
With batteries disconnected and no alarms present, measure voltage across the 0V and CHARG test
points on the 2006 power supply board and, if necessary, adjust the multi-turn potentiometer VR1 until
voltage is 27.3V 0.05V (27.25V – 27.35V).
Current limiting is factory preset and field adjustment is not required.
AC Input 30 VAC +10% -15%
Output Current 1.5 AMPS
Output Voltage 27.3 VDC
Current Limit 1.5 AMPS
Output Ripple 200 mV
External Power Supply (if fitted)
With batteries disconnected and no alarms present, measure voltage across Remote Input terminals on
IFS-2005 and adjust the voltage on the external power supply until the voltage is 26.5V 0.5V (26.0V –
27.0V). Note: This voltage is not critical for the operation of the IFS-2600 panel, but the voltage must not
go outside the limits as specified for the field ancillaries that it powers.
This supply is used in addition to the internal power supply for large systems. Its primary function is to
power any additional ancillary loads of the FIP up to 7 amps. This supply meets the requirements of
AS4428.5.
IFS-2006 – JP1 External PS Monitoring
When using external power supply, JP1 link on IFS2006E must be fitted to enable external PSU
monitoring.
Power Supply Comparator Reference Voltage TP10
With the panel in the quiescent mode, measure voltage between system 0V and TP10. Adjust multi-turn
potentiometer VR3 until voltage is 7.0V 1% (6.93V – 7.07V).
Non Adjustable Test Points
TP8 = 5.0 VDC 5% 5VDC POWER SUPPLY
TP5 = 12.0 VDC 5% 12VDC POWER SUPPLY
If these test point voltages are not correct, please return the main termination board to the factory for
repair.
