Properties
The power supply connects to (170W) FP2011-U1 with a maximum load of 6.5 A.

 The battery charger capable of charging up to 100 Ah batteries at a maximum of
6A.
 Power supply (170W) FP2011 must be used for batteries of 33 Ah or less.
 Ground faults detected at <1 kΩ to ground.
 Ground fault detection for all circuits except the two detector circuits handled by
Operating Unit. Each detector core has its own ground fault and supervision
circuit.
 Two integrated network circuit cards, one for circuits 1 and 2, one for circuits 3 and
4, and EMC surge protection for eight style 4 or four style 6 circuits.
 Maximum of 252 device addresses can be controlled per integrated network circuit
card.
 Three relay outputs and one user programmable relay output for common alarm,
common trouble, common supervision and user programmable.
 The auxiliary output is a regulated 24VDC output with a maximum of 1.5 A.
 Degraded alarm and trouble mode functions when either or both CPUs for the
periphery board or Operating Unit are compromised.
 Integrated NAC circuits, specified for 24VDC, configured for either one class A
(style Z) or two class B (style Y) circuits with a maximum of three A for one class A
or one of the two class B circuits. NACs have integrated synchronization protocol
for audible or visual notification appliances.
– All NAC circuits are supervised and protected for over current and direct short-
circuited output.
Two slots for optional extensions, one of which is for NAC module (1A/2B) or

releasing module (XCI2001-U1):
– NAC module (1A/2B) FCI2001-U1 for one additional class A circuit or two class
B circuits (same data as integrated NAC circuits) (P/N S54400-A54-A1). The
module connects to X901.
– Releasing module (XCI2001-U1) (P/N S54400-A69-A1) The module connects
to X901.
Additional peripheral data bus connection (X202) for LED or DACT modules.

Main CPU and detector core CPUs capable of being updated in the field through

the Operating Unit.
