BeamGuardianTell us about your siteBeamGuardianTell us about your siteBeamGuardian is an early-stage diagnostic concept being developed to help identify the real causes behind hard-to-diagnose optical beam detector faults — repeated alarms, intermittent behaviour, and problems that clear before the engineer arrives.
If you're dealing with a problem site, tell us about it. I'll review every submission personally and where I can see a pattern that matches something I've encountered before, I'll get back to you with my thoughts. No sales pitch. No obligation.

I'm Sean Quilliam, a hardware design engineer with over 20 years of experience. During my time at FFE I designed the Fireray One base from concept through to production, the Fireray 3000 transmitter, receiver and Hub hardware, and redesigned the Fireray Hub Reflective transceiver circuit — achieving a 20% increase in detection range. I also designed the hardware and wrote the production software for an optical beam detector at Spectiv, including the AGC algorithm and infrared signal processing.
Alongside the design work at FFE, I spent time in the field — visiting problem sites and providing direct technical support to installers and engineers. That field experience fed directly into the products I designed. BeamGuardian comes from the same place: the understanding that what works in a lab and what works on a difficult real-world site are two very different things.
Sean will review your submission personally. If your site matches a pattern worth discussing, he'll be in touch directly.
