16.000,00 EGP
The G8NB Beam Smoke Detector provides early fire detection in large open areas. It works well in buildings with high ceilings. These environments often limit the effectiveness of point smoke detectors.
This detector uses reflective optical technology to detect smoke. It transmits an infrared beam toward a reflector. Smoke reduces the signal level inside the beam path. The system analyzes this change and triggers an alarm when needed.
This method delivers fast response and stable performance.
The system supports detection distances from 10 to 100 meters.
For spans above 50 meters, installers use multiple reflectors.
Wide-area coverage reduces the total number of devices required.
Installers can configure alarm thresholds at 25%, 35%, 50%, or 75% obscuration. These settings allow adaptation to different site conditions.
Proper adjustment helps limit false alarms. The system also detects sudden beam blockage through a rapid obscuration fault function.
The G8NB unit supports quick and accurate installation. Alignment modes guide technicians during setup.
Fire and fault relay outputs allow direct connection to conventional fire alarm panels. The device operates on 15–32 V DC with low current consumption.
The detector operates reliably between -20°C and +55°C.
Its enclosure carries an IP40 rating for indoor use.
The housing meets UL94 V0 flammability standards.
This model complies with UL268 7th Edition requirements. The certification confirms dependable smoke detection performance in regulated fire alarm systems.
This detection solution fits large indoor spaces such as:
Warehouses
Factories
Logistics facilities
Shopping malls
Exhibition halls
Atriums
Aircraft hangars
