| ESL
500 Series 521CRXT / 541CXT
The
ESL 500 Series self-diagnostic, 2 and 4-wire photoelectric smoke
continually monitor their own sensitivity and operational status,
and provide a visual and remote trouble condition if they drift
out of the sensitivity range or fail internal diagnostics. The
521 has a unique CleanMe feature for remote maintenance reporting
that reduces false alarms on 2-wire module. Both models' photoelectric
smoke detector/fixed rate of rise heat detector includes fast
response algorithms for a quick response to both flaming and
smoldering fires. |
