F Number of standby hours (24 or 60 for NFPA 72, chapter 1, 1-5.2.5):
G Multiply lines E and F.
H Alarm sounding period in hours. (For example, 5 minutes =.0833 hours)
I Multiply lines E and H.

J Add lines G and I.

Note 1: Total does not include isolator devices or accessory bases.
Note 2: If you use door holders, you do not need to consider the door holder current for alarm/battery standby, because the power is removed during that
time. However, during the normal operation, the door holders draw current must be included in the 2.5A total alarm current (1.0A for all other conditions)
that can be drawn from the panel.
Note 3: Use the next size battery with a capacity greater than required.
Note 4: IDP-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.
power only when the test feature is used. This feature should be considered when you determine auxiliary power capacity, but are not calculated into
the current requirements for the day-to- day operation.
Note 4: The IDP-PhotoR is sold separately from the DNR. The current draw for the DNR + IDP-PhotoR is calculated by increasing the "Number of
Devices" column for each IDP-PhotoR used with a DNR.
Note 5: The DNR housing does not include a Relay circuit board. If a relay is needed, be sure to add one to the IDP-Relay & IDP-PhotoR "Number of
Devices" column for each DNR used for correct current calculations.
Note 6: The FACP can support 30 devices with LED's ON. This current draw is added to the panel's alarm current.
