Notification Appliances Current
Total current ratings of all devices in system (line A + line B + C)
Total current ratings converted to amperes (line D x .001):
Number of standby hours:
Multiply lines E and F.
Alarm sounding period in hours. (For example, 5 minutes = .0833 hours)
Multiply lines E and H.
Add lines G and I.
1.
The FACP can only support 5 devices w/LED's on. This current draw has been added to the panels alarm current.
2.
The SK-DUCT housing contains a vacant mount for a SK-RELAY (sold separately). Current draw for the SK-RELAY is calculated by
increasing the SK-RELAY row of the calculation sheet by one for each SK-RELAY used with a SK-DUCT.
3.
SK-BEAM-T draws a maximum of 500mA from Auxiliary power only when the test feature is used. this should be considered when
determining auxiliary power capacity but not calculated into current requirements for day to day operation.
4.
If using door holders, you do not need to consider door holder current for alarm/battery standby, because power is removed during that
time. However, during normal operation, door holders draw current and must be included in the 6.0A total current that can be drawn
from the panel.
5.
Use next size battery with capacity greater than required.
6.
Total does not include isolator devices or accessory bases.
2.6.3 Current Draw Worksheet for SD SLC Devices
Use Table 2.5 to determine current requirements during alarm/battery standby operation when SD SLC devices are installed.
For each device use this formula:
5895XL Intelligent Power Module
(Current draw from battery)
Additional 5895XL
(Daisy-chained to this module)
Addressable SLC Devices
SD500-AIM
SD500-MIM
SD500-PS
SD500-ARM
