P/N 10069 ECN08-0066
EXTERNAL 27VDC POWER SUPPLY
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
Important Notes:
When using external power supply, JP1 link on IFS2006E must be fitted to enable external PSU monitoring.
If this supply is used to power a NI-2008 gas module, the following additional components are required to
ensure a break free change over from the mains supply to the panel battery in case of mains fail condition.
1. A 6A4 or P600G rectifier diode (Notifier part number #266) is to be installed in series with the
external +27V output of the IFS-2600 termination board.
2. A 3300µF 50V Electrolytic Capacitor (Notifier part number #1248) should be installed across the
+27V and 0V of the ancillary device.
BATTERY TYPE AND CAPACITIES
In general, any Sealed Lead Acid Battery, or Wet Lead Acid Battery designed for stationary use is compatible
with the IFS-2600 Fire Indicator Panel. Automotive batteries must not be used. The use of Nickel Cadmium
batteries is not recommended.
