Zeta UI/IR | Zeta Alarm System | Flame Detectors

The new range of UV/IR and Triple IR Flame Detectors detect fuel and gas fires at long distances with the highest immunity to false alarms. The ZT-500EX can detect a 0.1m2 gasoline pan fire fire at 65m in less than 5 seconds. New features include RS484/RS232 compatabilities for digital communications; lower power requirements; and a compact, lighter design. ZT-500EX approved to ATEX by DNV for explosion-proof.
