System Components
Intelligent Detectors
Intelligent, addressable detectors provide analog information to the control
panel. The control panel continually processes this information to deter-
mine the alarm, maintenance, or normal status of each device. The sensitiv-
ity of each detector can be set by the programmer. Each detector responds
to an address that is set in the head via built-in rotary decimal switches.
The following table contains a list of the intelligent detectors that you can
use with an AFP-400 system.
