C Notification Appliances Current
D Total current ratings of all devices in system (line A + line B + C)
E Total current ratings converted to amperes (line D x 0.001):
F Number of standby hours
G Multiply lines E and F.
H Alarm sounding period in hours. (For example, 5 minutes = 0.0833 hours)
I Multiply lines E and H.
J Add lines G and I.
Multiply by the Derating Factor
Total ampere hours required
1 The FACP can only support 5 devices with LEDs on. The current draw has been added to the panels alarm current.
2 Total does not include isolator devices or accessory bases.
3 The IDP-BEAM-T draws a maximum of 500mA from auxiliary power when the test feature is used. This should be considered when
determining auxiliary power capacity but not calculated into current requirements for everyday operation.
4 The IDP-PHOTO-R/-W/-IV is sold separately from the DNR. Current draw for the DNR + IDP-PHOTO-R/-W/-IV is calculated by increasing
the "Number of Devices" column for each IDP-PHOTO-R/-W/-IV used with a DNR.
5 Maximum SBUS address capacity is determined by the amount of SBUS bandwidth consumed by each SBUS module. Refer to
Section 4.6.2 for SBUS limitations.
6 If there are door holders in the system, there is no 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 1.8 A total current that
can be drawn from the panel.
7 Use next size battery with capacity greater than required.
3.5.3 Current Draw Worksheet for SK SLC Devices
Use Table 3.3 to determine the current requirements during the alarm/battery standby operation when SK SLC devices are installed. You can
install up to 75 SK detectors and 75 SK modules
For each device, use this formula:
