2.7 System Configuration
The Spectrex model 20/20L, 20/20LB is a self-contained Optical Flame Detector
that can function as a stand alone unit directly connected to external devices as
alarm systems or automatic fire extinguishing systems. The same detector can
form part of a more complex system where a plurality of detectors and other
devices are integrated through a dedicated control unit.
2.8 Detector Types
This manual covers two types of detectors. Model 20/20LB and model 20/20L,
the difference is that Model 20/20LB includes a BIT and 20/20L does not include
this feature.
Both models are available in either Aluminum (Al.) housing, or Stainless Steel
(St.St.) housing.
There is an option for higher ambient temperature 185°F (+85°C) version if
specified.
