Calculating Current Draw and Standby Battery Before You Begin Installing
FCP-75 Manual — P/N:LS10147-003FK-E:A 3/17/2021 19
1. Total does not include isolator devices or accessory bases.
2. 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 2.5A total alarm current (1.0A
for all other conditions) that can be drawn from the panel.
3. Use next size battery with capacity greater than required.
4. The FIK-2351R is sold separately from the DNR. Current draw for the DNR + FIK-2351R is calculated by increasing the “Number
of Devices” column for each FIK-2351R used with a DNR.
5. The DNR housing does not include a Relay circuit board. If a relay is needed, be sure to add one to the FIK-M500R & FIK-2351R
“Number of Devices” column for each DNR used for correct current calculations.
6. The FACP can only support 5 devices w/LED’s on. This current draw has been added to the panels alarm current.
