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-20P and the ZT-20EX can detect a 0.1m gasoline pan fire at 30m in less than 5 seconds. The ZT-500EX can detect the same 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-20EX and ZT-500EX series are approved to ATEX by DNV for explosion-proof.
