EC-50R | Edwards Signaling Reflective Beam Smoke Detector 15–160 ft Range 10.2–30 VDC

Edwards Signaling · Fire & Life Safety

Description  The Edwards Signaling EC-50R Reflective Beam Smoke Detector is a long-range optical smoke detection system designed for open-area protection in commercial and industrial facilities. Using a projected infrared beam and reflector, it monitors large spaces for smoke presence across distances from 15 ft to 160 ft. Operating on 10.2–30 VDC, the EC-50R provides reliable detection performance with low current draw and built-in alarm and trouble relays.     Technical Specifications  Condition New/Never Used Surplus Brand Edwards Signaling Category Fire Detection Equipment Part Number EC-50R Subcategory Beam Smoke Detectors Detection Method Infrared Reflective Beam Beam Coverage 15 ft – 160 ft (length), 30 ft width per side Power Supply 10.2–30 VDC Continuous Standby Current <4 mA Alarm/Trouble Current <14 mA Alarm Relay Normally Open, 2A @ 30 VDC resistive Trouble Relay Normally Closed, 2A @ 30 VDC resistive Operating Temperature 32°F to 100°F (0°C to 37°C) Operating Humidity Up to 93% RH, Non-Condensing Reset Time >5 Seconds (Power Down) Signal Delay 10 Seconds (Alarm/Trouble) Dimensions (H x W x D) 8.25 x 5.1 x 4.7 in (21 x 13 x 12 cm) Mounting Type Wall-Mount Reflective Alignment Enclosure Durable Plastic Housing Application Open-Area Fire Detection (Warehouses, Atriums, etc.) Weight 1.5 lbs (0.68 kg)   Information About EC-50R The EC-50R is part of the Edwards Fire Detection Series, engineered for monitoring wide open areas such as warehouses, atriums, and assembly halls where traditional spot detectors are impractical. It operates by projecting an infrared beam toward a reflector and analyzing the amount of light returned, detecting smoke when beam intensity decreases. The detector includes adjustable sensitivity settings, separate alarm and trouble relay outputs, and a built-in signal delay to minimize false alarms. Designed for easy alignment and stable performance, the EC-50R provides dependable smoke detection across large coverage areas in varied environmental conditions. Key Features: Long-Range Coverage: Monitors distances from 15 ft to 160 ft with a 30 ft width on either side of the beam. Reflective Beam Design: Simplifies installation by requiring only one electrical connection point. Wide Operating Voltage: Functions on 10.2–30 VDC continuous power for system flexibility. Low Current Draw: Consumes less than 4 mA in standby and under 14 mA in alarm or trouble states. Alarm and Trouble Relays: Includes independent contacts for system monitoring and integration. Environmental Resilience: Operates up to 93% relative humidity and from 32°F to 100°F. False Alarm Reduction: Built-in 10-second signal delay and >5-second power reset to ensure stability. Compact, Lightweight Design: Simplifies mounting and maintenance with a total weight of just 1.5 lbs. The EC-50R delivers the reliability and precision required for large-area smoke detection in commercial, industrial, and institutional facilities.
