Auxiliary power only:
In order to connect a circuit using power-limited wiring, the devices
being powered must all be addressable, or a UL-Listed EOL relay must be used to supervise
the circuit. Refer to the figure below for wiring directions for the EOL relay.

Figure 9. The EOL Relay
The Notification Appliance Circuits on the XPS are rated for Special Application and for
Regulated 24V dc operation per UL864, 9th Edition.
When used with the Notification Appliances listed in Table 5 or Table 6, each NAC is rated
for 3A, and total XPS capacity is rated at 9A. This rating is the UL864 Special Application
rating. Appliances listed in Table 5 and Table 6 are synchronized per UL864, between all
NACs on the XPS, and any NACs on an SPS, RPS or XPS within the same 4100U/4100ES
system, but not if appliances are mixed from both tables. Appliances from table 5 will be 1/2
second out of audible sync with appliances from table 6 in the same system. All appliances
any given SPS, RPS or XPS must be from either Table 5 or Table 6, mixing of appliances
from both tables is not possible within a power supply .
For use with Notification Appliances not listed in Table 5 or Table 6, each circuit is rated for
2A maximum, with a total Notification Appliance load of 4A per XPS. This rating is the UL
864 Regulated 24V dc rating. Synchronization of strobes and other appliances requires use of
the associated, Listed, compatible Synchronization Module. Consult supplier of Notification
Appliances for synchronization limits and details.
Non-pulsing, linear-type Notification Appliances, such as horns or bells may be used up to the
full rating (3A / NAC, 9A total for the XPS).
If Wheelock appliances employing EZ Mount SNAP bases are used, reduce the wiring
distance and wiring resistance by:
12 gauge wire: 7.0 feet per appliance, 0.025 Ohms per appliance
14 gauge wire: 4.4 feet per appliance, 0.025 Ohms per appliance
16 gauge wire: 2.8 feet per appliance, 0.025 Ohms per appliance
18 gauge wire: 1.8 feet per appliance, 0.025 Ohms per appliance

Note:
The 2098-9739 Relay is
used as an example.
Other UL-Listed EOL
relays can be used,
depending on the
application.
