8 Zones Gas Detection Panel


Central gas detection system with 8 zones to which it is possible to connect a toxic or explosive gas detector of proportional type 4-20mA. LCD display with 4 lines of 16 characters, membrane keyboard with protected access via mechanical key, 6 programmable relay outputs for pre-alarm, alarm and general fault with threshold management. The system allows to have up to 22 programmable outputs through an optional board (NFG-16R). Equipped with LED signaling for pre-alarm 1, pre-alarm 2, alarm, sensor disabled and fault. ATEX and SIL1 certified.

• 8 selectable languages
• Programmable labels: 32 characters
• Programmable alarm threshold for sensors.
• Decision algorithms for alarm, pre-alarm and fault criteria.
• Logging file of 1.000 events consultable from display and downloadable on PC
• Real time clock.
• Key switch with 3 positions for enabling control functions
• TEST and MAINTENANCE modes of the system
• 6 programmable Relay outputs with 8A 250V contacts on board, expandable with 16 relays 6A 250V board.
