The NW-8300-2 is a high-performance fire alarm control panel designed for reliability and efficiency in fire detection systems. It operates on a mains voltage range of 110-240 AC (±10%) at 50Hz and utilizes a dual 12V 7Ah battery for backup power. The system maintains a nominal voltage of 29V DC, with a maximum ripple of 200mV. This model features a charger capable of supporting batteries up to 7Ah within 24 hours. The zone voltage is set at a nominal 21V DC (ranging from 20-22.5V), ensuring optimal performance of connected devices. The sounder activation delay can be adjusted from 0 to 18 minutes in 30-second increments, providing flexibility in alarm response times. For enhanced circuit protection, both the zone and sounder utilize a 4.7kΩ end-of-line resistor, and the system includes short circuit protection for both zone lines (set at 100mA) and charger (for batteries below 20V). The supply voltage is maintained at 27V (±1V), ensuring stable operation. The overall dimensions of the panel are 400 x 350 x 105 mm.
