END OF LINE FIBERGLASS NEMA-4X

Fiberglass NEMA-4X (IP66) end-of-line box with test switch and U-ELR-1 end of line resistor device. The ELR-HD-U consists of the U-ELR-1 Universal End-ofLine Resistor device mounted in a NEMA 4X enclosure. Used to terminate Class B detection circuits of fire alarm system employing Protectowire Line Type Heat Detector, the U-ELR-1 is furnished with quick connect clamping type terminals which makes it possible to fasten the detector directly to the terminals. All bends in the Protectowire Line Type Heat Detector should have a minimum radius of 2.5in (6.4cm). The U-ELR-1 Universal End-of-Line Resistor device is furnished with a Test Button. When the Test Button is pressed the detection circuit is shorted to simulate an alarm condition
