Intelligent Addressable Devices

Edwards brand intelligent addressable detectors are meticulously engineered to deliver high-performance features, superb reliability, and unbeatable quality. With their highly stable design, these detectors resist air movement caused by heating and air conditioning, making them reliable performers ideally suited to modern building interiors.

The installation and maintenance advantages of Edwards intelligent addressable detectors add value throughout their service life. The twist-and-lock design makes short work of installation and maintenance operations. A plastic breakout on the detector housing optionally prevents removal from the base except with a special tool.

A bright, dual color LED flashes red when the detector is in alarm, and green for normal polling, thus eliminating much of the guesswork when responding to front-panel indications.

Device Loop

The E-FSA64 control panel provides one device loop circuit that supports 64 addresses. The E-FSA250 panel supports 127 addresses and can be expanded to provide a second loop of 127 addresses by means of the XAL127 SLC Loop Expansion Module for a panel maximum of 254 addresses. All loop circuits are supervised for opens, shorts, and grounds. All addresses can be used for any device type maximizing loop flexibility.

Circuit Specifications

Intelligent Addressable Devices

All detectors f-eature comprehensive self-diagnostic capability. E-PD and E-PHD photoelectric detectors continuously adjust their sensitivity to compensate for changes in the environment such as the presence of dirt, smoke, temperature, and hum- idity. Th-ese detectors are factory set to issue a dirty sensor warning when they reach 80% of their compensation limit and a trouble condition when they reach 100%. The Edwards intelligent panel allows you to adjust the sensitivity settings during programming to meet the needs of the application.
