Adjust viewing area to see up to column V Make entries in yellow highlighted cells Fill out the battery calculation section for each booster power supply needed. You will have to keep track of each battery size calculated, then at the end, enter the number of booster power supplies using the particular size battery. In most cases, 12V6A5 batteries can be used. Each BPS will require 1 pair of batteries. Step 5a - Detailed booster bower supply battery calculations This is for supervisory current from devices such as remote annunciators and sounder bases connected to signal circuits that have been configured as AUX outputs (not supervised) and will stay powered if loss of AC (battery backed up). Supervisory (AUX1, AUX2, AUX3, AUX4) Note: Only add auxiliary current if aux output stays on after AC power failure.
