19-22V DC Nominal (EW5204-4) Extinguisher Control Panel

The EW5204-4 Extinguisher Control Panel is designed for effective fire safety management, featuring advanced capabilities to monitor and control extinguishing systems. It operates on a mains voltage of 110-240 AC (+/- 10%) at a frequency of 50Hz, ensuring compatibility with various power supplies. This panel utilizes a battery system of two 12V / 1.3 Ah batteries, providing reliable backup power for continuous operation. The nominal system voltage ranges from 19-22V DC, with a maximum voltage ripple of 200mV. It can charge up to 1.3 Ah in 24 hours, ensuring that the batteries remain fully operational. The EW5204-4 supports four zones, each capable of handling up to five devices. Each zone has a voltage of 24V DC (22-24V), and features sounder alarm outputs for effective notification—two available for each zone. The panel includes relay outputs for fault and fire signals, capable of handling a maximum current of 1A. Additional features include sounder activation delays ranging from 0 to 18 minutes in 30-second increments, end-of-line devices with a 6.8kΩ resistor for both zones and sounders, and short circuit protection for both the zones and charger.
