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.
3.7.4 Current Draw Worksheet SD for SLC Devices
Use Table 3.4 to determine current requirements during alarm/battery standby operation when SD SLC devices are installed. The IFP-
300 FACP supports up to a total of 127 SD SLC devices per loop, consisting of any combination of devices.
