All wiring is 18 AWG (0.8231 mm
2
) (minimum) to 12 AWG (3.309 mm
2
) (maximum).
All wiring is supervised and power-limited.
The maximum alarm current is 3 A per circuit. The supervisory current is 2.03 mA at
24 VDC.
The nominal voltage rating is 24 VDC, 2 V p-p ripple (maximum).
The total available current from the XPS is 9 A, unless it is used for REGULATED 24 DC
notification appliances, where the XPS is rated for 4 Amps notification current, and 1 Amp
for other uses. Total available auxiliary power current is 5 A (1 Amp for REG 24), and rated
at 2 A per circuit. Current used for card power by modules plugged into the PDI, as well as
any auxiliary 24 VDC current, must be deducted from the total 9 A available current.
All wiring that leaves the building requires overvoltage protection. Install module
2081-9044 (3 A) or 2081-9028 (¼ A) inside a UL-Listed electrical box wherever wire enters
or exits the building. When using the 2081-9044, the maximum alarm current is reduced to ¼
A for that part of the circuit downstream of the module.
Terminal designations “+” and “-” are for the alarm state.
Compatible appliances for NACs are listed in table 5.
A maximum of 70 appliances can be supported per circuit.
For CE compliant systems, use the ferrite beads as shown in each figure. Loop wires once
through the ferrite bead(s) as shown in Figure 8. 4100-5129 includes 3 ferrite beads, order as
needed
