The Fireray One

With no specialist tools or knowledge needed for installation and operation, the Fireray One is a standalone beam detector that prioritises ease of installation.
Using the Fireray One, it couldn’t be easier to bring the benefits of beam detection to your application:
– One Minute Auto-Alignment™ – just steer the laser onto the Reflector, then
at the flick of a switch, it aligns itself. 8 times faster than previous detectors
– One person installation – everything can be done by one person
– One standalone product – no specialist tools required; minimal prior knowledge
and training needed.


Detection performance
Detection range 0 to 50m
0 to 120m with Refl ective Long Range Kit
Alignment method Laser assisted, Auto-Alignment™. Manual alignment – optional setting
Auto-Alignment™ protocol Background check, Box search, Adjust and Centre
Building Movement Tracking™ Compensates for natural shifts in alignment from building movement*
Contamination Compensation Compensates for gradual build-up of contamination on the optical surfaces
Light Cancellation Technology™ Compensates for high levels of sunlight and artifi cial 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 refl ectors 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
Confi gured 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


User features
Integrated user interface Alignment mode switch, alignment directional buttons and confi guration switches for alarm
response threshold
Alignment status indication 2 Green LEDs and 1 Yellow LED
System status indication Normal operation – Green LED fl ashing every 10 seconds
Alarm condition – Red LED fl ashing every 10 seconds
Fault condition – Yellow LED fl ashing every 10 seconds for obscuration or every 5 seconds
for contamination
Cleaning Flat front face with enclosed optics. Cleaning the optics does not affect alignment
