Battery charging
In normal operating mode
: the battery charger (re)charges the batteries and maintains them
when they are fully charged. The maximum current that can be provided to the main outputs
and auxiliary outputs is Imax a.
In back-up operating mode
: the total operating current is provided by the batteries and
battery charger (when mains present) and may not exceed ‘Imax b.
Authorized batteries
If Imax b is greater than 100 A, use batteries with a capacity of
86
Ah to
225
Ah and set
daughter board jumper on ‘75’ (see
Figure 5.1
).
If Imax b is less than 100 A, use batteries with a capacity of
65
Ah to
225
Ah, and set daughter
board jumper on ‘50’ (see
Figure 5.1
).
The following batteries are approved:
–
Yuasa NPL series
–
Powersonic GB series
–
ABT TM series
–
Enersys VE series
–
Effekta BTL series
–
Long GB series.
CAUTION!
If a mains failure occurs either on the battery charger, the connected system or on both (the
system turns on ‘back-up operating’ mode, mains not present condition) an alarm must be
generated on the Voice Alarm System.
Imax a
Maximum available current which may be drawn continuously while charging
the battery:
- Imax a = 12 A - Icharge.
- Icharge = C/20 (C = battery capacity)
Imax b
Maximum allowed current which may be drawn from the batteries when the
mains supply is not available on one or more of the system units:
- Imax b = 150 A if the jumper is set on '75'
- Imax b = 100 A if the jumper is set on '50' (see
Figure 5.1
).
