Specific features and technical specifications
If your amplifiers are not supplied by the same mains as the Power Supply Equipment, a failure of the mains
of the amplifiers must generate an alarm to the voice alarm system.
In normal operating mode
: the Power Supply Equipment recharges the batteries and maintains them when
they are fully charged. The maximum current that can be provided to the user outputs is Imax a.
In back-up operating mode
: the total operating current is provided by the batteries
and may not exceed ‘Imax
b mains not present’.
Imax a : maximum available current which may be drawn continuously while charging the battery.
Imax a = 12A
– C/20 (C : battery capacity in Ah).
Imax b (mains present) : maximum available output current which may be drawn a short time, during which
the battery may not be charged, but not discharged.
Imax b (mains present) = 12 A
Imax b (mains not present) : maximum available current which may be drawn from the batteries when the
mains supply is not available, 150A if the jumper is set on '75', or 100A if the jumper is set on '50' (see
figure 1).

Back-up duration and battery size
To determine the battery size according to the required back-up duration of your power supply and interpret
the battery code dates, consult our website: www.slat.fr

Authorized batteries
-
If Imax b (mains not present) is greater than 100A, use batteries with a capacity of
86 to 225 Ah
and
set daughter boar
d jumper on ‘75’.
-
If Imax b (mains not present) is less than 100A, use batteries with a capacity of
65 to 225Ah
, and set
daughter board jumper on ‘50’.
Figure 1 : Location of the jumper
The jumper
is set on the ‘50’ position as factory setting. Any other position of the jumper operates like ‘50’ except the
‘75’ position.
