1.1 Product Overview
The Spectrex Model 20/20U, 20/20UB is a UV Flame Detector. It is designed to
sense the occurrence of fire and flames and subsequently activate an alarm or
an extinguishing system directly or through a control circuit for maximum fire
protection. It uses innovative technology of advanced digital signal processing to
analyze the dynamic characteristics of fire.
The Difference between models is that Model 20/20UB includes a Built-In-Test
(BIT) function while the 20/20U does not include the BIT.
Detection performance is controlled by a microprocessor and easily adapted to
all environments, applications and requirements. The result is a unique and
superior flame detector that provides excellent detection sensitivity with extreme
immunity to false alarm.
