The digital emergency management ESP-2000 B was developed for voice alarm systems, which must correspond to the standard  VDE 0833 - part 4. All errors are displayed and reported on fault signal contacts, as well as a buzzer and an LED. The device is still certified to EN 54-4.

Please consider the following features:

• Network fault monitoring with switchover to standby power mode.
• Monitoring of battery errors (with internal resistance measurement).
• Monitoring of the 6 or 12 power outputs for amplifiers.
• Function for a balancing charge to avoid different voltages of the individual battery cells.
• A quick charge function with up to 16A or 32A, allows a rapid recharge the battery packs even with large capacities.
• Fault signal are realized in the event of a fault with sloping relay.
• Integrated depth discharge protection for 24 V batteries.
• Fault indication signal through LED´s on the front side of the device and fault indication contact (potential-free changeover contact) on the rear side of the device.
• A temperature sensor adjusts the allowed charge current to the existing temperature in the PA cabinet.
• All commercially available lead-acid batteries can be used.
• Equipped with a switching power supply and digital charger unit.
• USB interface to configure operating parameters.
• Configuration software in scope of supply.
