ESL 320ACC Smoke Detector w/ Relay









Smoke Alarm, Photoelectric, 120VAC, Initiating Alarm Relay, Connector Compatible with ESL 320CC

Discontinued - No Direct Replacement


320A/350 Series alarms are single/multiple station photoelectric AC smoke alarms designed for use in residential occupancies, including hotels, motels, and dormitories. The 320A/350 Series is compatible with existing 320 Series wiring and up to twelve units may be interconnected for tandem operation. When any unit in tandem senses smoke, all the units sound an alarm.

The 320A/350 Series features a test/silence button on the front of the alarm that facilitates testing. The series continuously monitors its own sensitivity; and if the alarm falls out of sensitivity, GE's proprietary field replaceable optical chamber enables quick and easy cleaning and maintenance. The series meets NFPA 72 field sensitivity requirements without the need for external meters.

The 350 Series provides a battery backup that offers up to 46 hours continuous protection in the event of a power outage. Other models provide auxiliary relay options.

All models are photoelectric alarms, which detect smoldering fire faster than the more common ionization alarms. Since smoldering fire is one of the most prevalent types of residential fires, photoelectric alarms are essential in these applications.
