The NW-8300-4 is a robust conventional fire control panel designed for effective fire detection and alarm management in various environments. It operates on a mains voltage range of 110-240 AC (±10%) at 50Hz and utilizes dual 12V 7Ah batteries, ensuring reliable backup power. The system maintains a nominal voltage of 29V DC, with a maximum ripple of 200mV, guaranteeing stable operation. This model supports a zone voltage of 21V DC (ranging from 20-22.5V) and can accommodate up to 20 devices per zone, providing extensive coverage for fire detection. Users can set the sounder activation delay from 0 to 18 minutes in 30-second increments, allowing for flexible alarm response times. The panel features 4.7kΩ resistors for both zone and sounder end-of-line devices, enhancing circuit integrity. For safety, it includes short circuit protection for both zones (set at 100mA) and the charger (for batteries below 20V). The supply voltage is maintained at 27V (±1V), and the panel dimensions are 400 x 350 x 105 mm.
