ESL 240-COe Carbon Monoxide Alarm ESL 240-COe Carbon Monoxide Alarm

The ESL 240-COe Alarm is the only industrial-grade Carbon Monoxide (CO) alarm specifically developed for use in a monitored home security system. It operates on a unique industrial-grade electrochemical sensor that continuously monitors for CO and is unaffected by temperature variations. The sensor communicates with a sophisticated on-board microprocessor that accurately
calculates CO levels and exposure time. Its 85dBa temporal 4-sounder provides distinctive alarm notification.

320A/350 Series Photoelectric Smoke Alarms

320A/350 Series Photoelectric Smoke Alarms

The ESL 320A/350 Series alarms are single/multiple station photoelectric 120VAC smoke alarms. Both models have a field-replaceable optical chamber and a test/silence button and are self-diagnosing.. A battery backup on the 350 model helps provide continuous detection.

ESL 500 Series 521CRXT / 541CXT

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.
