System Sensor Intelligent Sensors offer features and
performance that surpass conventional sensors. The
sensitivity of models 1551B, 2551HR, and 2551THR can be
“set” individually in the panel software. The sensors may
be continuously monitored for changes in sensitivity and
compensate for dirt, temperature, or humidity to maintain
the set sensitivity. Model 5551R offers a rate-of-rise
temperature response while the 5551B offers a fixed
temperature response.
