Chapter 5 The System Power Supply (SPS)
SPS Specifications (continued)
SPS Current
Consumption
Table 5-2 summarizes battery standby capabilities for the SPS. Voltage assumed is 24 VDC,
which is the rated battery voltage for lead-acid type batteries.
Note:
• Additional standby conditions: Trouble relay activated, power trouble LED on, IDNet LED on, battery
charger off, auxiliary power load = 0 mA
• Additional alarm conditions: Trouble relay activated, power trouble LED on, IDNet LED on, battery
charger off, auxiliary power load = 0 mA, NAC alarm load = 0 mA, IDNet = 35 V
The Notification Appliance Circuits on the SPS are rated for Special Application and for
Regulated 24 VDC operation per UL864, 9th Edition.
When used with the Notification Appliances listed in Table I (Appendix I) or Table J
(Appendix J), each NAC is rated for 3A, and total SPS capacity is rated at 9A. This rating is the
UL864 Special Application rating. Appliances listed in Table I or Table J are synchronized per
UL864, between all NACs on the SPS, and any NACs on a SPS, RPS, or XPS within the same
4100ES system.
For use with Notification Appliances not listed in Table I or Table J, each circuit is rated for 2A
maximum, with a total Notification Appliance load of 4A per SPS. 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.
Simplex Appliances (Table I) May not be mixed with Wheelock Appliances (Table J) on a
single power supply. A 4100ES system with mix of appliances from Table I and Table J will
not meet the UL 864 9th Edition requirement for Visual synchronization (10 milliseconds)
between power supplies. Appliances listed in Table I will be consistently out of visual sync
with appliances in Table J by about 30 milliseconds. Appliances listed Table I will be notably
out of audible sync with appliances in Table J by a consistent (Wheelock leading by 1/2
second). In order to meet the requirements for visual and audible sync system wide, all
appliances in the system must be exclusively from either Table I or Table J.
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 SPS).
