Specific features and technical specifications
The Power supply and the public address and voice alarm system must be powered by the same mains
.
In normal operating mode
: The power supply equipment recharges then maintains on charge from the normal backup
supply, and provides current to the voice alarm system lower than Imax a.
In emergency operating mode
: the total operating current is provided by the battery, including the current of the PA/VA
amplifiers not exceeding ‘Imax b mains not present’ (
≤
150A) depending on the size of the battery.
Imax b = 150 A (mains not present).
Imax b = 12 A (mains present).
Imax a = 12A – C/20 (battery capacity).
