Notice!
All wiring except the battery terminal and primary AC power is power-limited.
Power-limited and non-power-limited circuit wiring must remain separated in the cabinet by
at least 0.25 in. (64 mm). Primary AC and battery wires must be tied to prevent movement.
Power-limited and non-power-limited circuit wiring must enter and exit from the cabinet
through different knockouts or conduits.
The length of wire allowed between the control panel and the last device on a wiring run
depends on the current drawn on that wiring run. Reducing the number of devices on a wiring
run allows the individual runs to be longer.
If not specified, use wire gauge AWG 12 to 18 (ISO 4 mm
2
to 0.75 mm
2
).
Circuit Type
[Terminals]
Circuit Function
Power Rating / Wire Type / Limitations
AUX [FWR-/FWR+]
Full Wave Rectified,
non-switched, FWR
Connects to
control modules,
annunciators and
accessories
24 V FWR (17 to 31 V FWR), 500 mA
Refer to the manufacturer's installation instructions
of the connected device for proper wiring and other
limitations
AUX power is non-supervised. For proper
supervision, use an end-of-line (EOL) power
supervision device such as a D275
AUX [RST-/RST+]
Resettable,
switched and
filtered
Connects to 4-
wire smoke
detectors
24 V DC (17 to 31 V DC), 500 mA
Refer to the manufacturer's installation instructions
of the connected device for proper wiring and other
limitations
AUX power is non-supervised. For proper
supervision, use an end-of-line (EOL) power
supervision device such as a D275
OPTION BUS
[Y/G/B/R]
Connects to
annunciators and
modules
12 V DC, 500 mA
Untwisted, unshielded pair, avoid twisted, shielded
pair (for maximum wiring distance, see
Option Bus,
page 67
)
NAC 1
[A1-/B1-/B1+/A1+]
NAC 2
[A2-/B2-/B2+/A2+]
Connects to NAC
devices
Nominal 24 VFWR (17 to 31 VRMS)
non-synchronized: 2.5 A per NAC
synchronized: 2.75 A NAC 1+NAC 2 in total
limited to 4.0 A (shared by NAC, OB and AUX)
In alarm, the distance limitation is set by the
maximum line drop (use the
FPA-1000_Battery_Calculator.xls at
www.boschsecurity.com)
Refer to the manufacturer’s specifications for
voltage range
