Description
The FRAY-ONE-UL is a cost-effective and easy-to-mount retroreflective line beam detector. It covers distances from 5m to 120m. One reflector enables accurate detection of smoke particles within the given distance range. For ranges between 5m and 50m, a single prism is sufficient. For ranges between 5m and 120m, four prisms are required. Additional prisms are included in the FRAY5000-LR-KIT. Main application areas are large rooms such as those in historical buildings, churches, museums, shopping malls, industrial buildings, warehouses, etc. The FRAY-ONE-UL is suitable for use in areas where point-type detectors are not effective.
- Integrated control unit

Detection performance
- • Detection range: 0 to 50 m or 0 to 120 m with long range reflector kit
- • Alignment method: Laser assisted, AutoAlignment™. Manual alignment - optional configuration
- • Auto-Alignment™ Protocol: Background Check, Frame Search, Adjust and Center
- • Building Movement Tracking™: compensates for natural shifts in building movement alignment
- • Contamination Compensation: Compensates for the gradual build-up of contamination on optical surfaces
- • Light Cancellation Technology™: compensates for high levels of sunlight and artificial lighting • Smoke Detection - Optical wavelength: 850nm near infrared (invisible)
- • Integrated laser - laser alignment: 650 nm visible Class IIIa < 5 mW
- • Dynamic beam phasing – allows beam detectors to be mounted opposite each other with reflectors in between. Eliminates false alarms caused by interference between beams
- • Signal output: individual alarm and fault relays (dry contact) 0.5 A at 30 V DC Programmable user configuration
- • Alarm response threshold levels: – 25% - <7 m – 25%, 35% - 7 m - 17 m – 35%, 55% - 17 m - 33 m – 55%, 85% - 53 m - 120 m
- • Alarm delay: 10 seconds, for momentary partial obstruction of the beam path • Fault delay: 10 seconds, for momentary obstruction of the beam path User features
- • Integrated user interface: alignment mode switch, directional alignment buttons, and alarm response threshold setting switches
- • Alignment status indication: two green LEDs and one yellow LED
- • System status indication:
- – Normal operation: Green LED flashing every 10 seconds
- – Alarm condition: Red LED flashing every 10 seconds
- – Fault condition: Yellow LED flashing every 10 seconds in case of blackout or every 5 seconds in case of contamination
- • Cleaning: Flat front face with closed optics. Cleaning the optics does not affect alignment.
