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.
o 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.
o In back-up operating mode:
The total operating current is provided by the batteries and may not exceed ‘Imax b mains not
present’.
o Imax a : maximum available current which may be drawn continuously while charging the
battery.
o Imax a = 12A C/20 (C : battery capacity in Ah).
o 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.
o Imax b (mains present) = 12 A
o 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).
The jumper is set on the ‘50’ position as factory setting. Any other position of the jumper
operates like ‘50’ except the ‘75’ position.
Authorized batteries:
o If Imax b (mains not present) is greater than 100A, use batteries with a capacity of 86 to
225 Ah and set daughter board jumper on ‘75’.
o 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’.
