Connecting power
Batteries
Do not connect the battery until all other wiring is complete.
Note:
A sealed, rechargeable, lead acid battery or gel type battery is required to meet UL requirements for power standby times.
Connect the RED battery lead to the positive battery terminal and the BLACK battery lead to the negative battery terminal.
The panel can be programmed to charge the battery at 400 mA or 700 mA. (
See "[982] Battery Settings" on page 160
).
Refer to "Aux loading and battery selection" on page 53.
Battery selection chart
After calculating the battery capacity
(B)
for each specific installation use the following table to determine the battery required to
support the main panel in standby mode for:
l
4 hours (UL/ULC residential burglary, ULC commercial burglary)
l
12 hours (EN50131 Grade 2/Class II)
l
24 hours (UL/ULC residential fire, UL home health care, ULC commercial burglary, ULC residential fire with wired CO
detectors UL985 6th Ed, ULC, fire commercial monitoring- no bell load allowed; INCERT [Belgium])
l
30 Hours (AC fail transmission required) or 60 hours (EN50131 Grade 3)
l
36 Hours (NFA2P 2 shield) or 60 hours (NFA2P 3 shield)
The battery size is measured in amp hours (Ah). The current values in the table denote the maximum current draw permitted to
achieve the desired standby time with the listed battery types.

* Use 2 x 7 Ah batteries connected in parallel, UL/ULC installations only
** with high current battery charge option enabled: [982].
Note:
Battery capacity deteriorates with age and the number of charge/discharge cycles. Replace every 3-5 years.
