Eazy Beam DS

Eazy Beam is an Optical smoke beam detector with range of 50 meter or 120 meter (with Reflective Long Range Kit) that can be installed easily and quickly by a single person in single point of wiring & commissioning. It has special feature to compensate automatically for natural building movement to continuously maintaining alignment by building movement tracking technology.

Eazy Beam Features

  • Auto alignment
  • Easy Installation
  • Standalone Detector

Salient Features

  • Alignment mode switch, alignment directional buttons and configuration switches for alarm response threshold
  • 2 Green LEDs and 1 Yellow LED for alignment status.
  • System status : Green LED flashing every 10 sec in normal condition
    Red LED flashing every 10 sec in alarm condition
    Yellow LED flashing every 10 sec for obscuration or every 5 sec for contamination in Fault condition .
  • Flat front face with enclosed optics. Cleaning the optics does not affect alignment.
  • UL Listed.

Detection Performance

Detection range:0 to 50m
0 to 120m with Reflective Long Range Kit
Alignment method:Laser assisted, Auto-AlignmentTM. Manual alignment – optional setting
Auto-AlignmentTM protocol:Background check, Box search, Adjust and Centre
Building Movement TrackingTM:Compensates for natural shifts in alignment from building
Contamination Compensation:Compensates for gradual build-up of contamination on the optical surfaces
Light Cancellation TechnologyTM:Compensates for high levels of sunlight and artificial lighting
Optical wavelength – smoke detection:850nm near infrared (invisible)
Integrated laser – laser alignment:650nm visible. Class IIIa <5mW
Dynamic Beam Phasing:Allows beam detectors to be mounted facing each other with the
reflectors in the middle. Eliminates false alarms caused by
crosstalk between beams
Signal output:Individual Alarm and Fault relays (VFCO) 2A @ 30 VDC

Programmable User Settings

Alarm response threshold levels:25% (1.25dB) – Fastest response to smoke
35% (1.87dB) – Default value
55% (3.46dB) – High immunity to false alarms, slow response to smoke
85% (8.23dB) – Highest immunity to false alarms, slowest response to smoke. Configured via the integrated user interface
Delay to Alarm:10 seconds, for momentary partial obstruction of the beam path
Delay to Fault:10 seconds, for momentary obstruction of the beam path
