1. Scope
1.1 Product Overview
The Spectrex Model 20/20L, 20/20LB is a UV-IR 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 the Models is that Model 20/20LB includes a Built In Test
(BIT) function while the model 20/20L does not.
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.
