• The notification appliance circuits on the XPS are rated for special application and for regulated 24 VDC operation in accordance with UL864,
9th Edition.
• When used with the notification appliances listed in Table 4 or Table 5, each NAC is rated for 3 A, and total XPS capacity is rated at 9 A. This
rating is the UL864 special application rating. Appliances listed in Table 4 and Table 5 are synchronized in accordance with 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 4 will be 1/2 second out of audible sync with appliances from Table 4 in the same system. All appliances any
given SPS, RPS or XPS must be from either Table 4 or Table 5, mixing of appliances from both tables is not possible within a power supply.
• For use with notification appliances not listed in Table 4 or Table 5, each circuit is rated for 2 A maximum, with a total notification appliance
load of 4A for each XPS. This rating is the UL 864 regulated 24 VDC 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 (3 A/NAC, 9 A 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 ft for each appliance, 0.025 ohm for each appliance
14 gauge wire: 4.4 ft for each appliance, 0.025 ohm for each appliance
16 gauge wire: 2.8 ft for each appliance, 0.025 ohm for each appliance
18 gauge wire: 1.8 ft for each appliance, 0.025 ohm for each appliance
