Device

For each device use this formula:

AL1002ULADAJ

(Current draw from battery)

Auxiliary Devices

C Notification Appliances Current must not exceed 10A (10,000mA)

D Total alarm current

E Total current ratings converted to amperes (line D x 0.001)

F Number of standby hours (24 for NFPA 72, Chapter 1, 1-5.2.5).

G Multiply lines E and F.

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 line J by 1.30.

(30% extra insurance to meet desired performance)

Total ampere - hours required

Units are capable of recharging 36AH battery max. If total ampere - hour required exceeds 36AH,

decrease AUX current to provide enough stand-by time for the application.
