Scantronic Xcel PIR Sensor Design

The Scantronic Xcel series of detectors introduced a housing for wired and wireless standard and pet tolerant PIRs. (Passive Infra-Red). They encompass some market leading functions including,

  • Advanced design with 30% range improvement; greater performance for improved security.
  • Consistent and 50% improved coverage due to advanced spherical lens design, five layers of beams and dual element sensors.
  • Unobtrusive design using high quality PC/ABS materials with superior surface quality, rigidity and uniformity of color.

Optima were approached to provide  ground up design, based on generated concepts, which not only ensured adherence to predetermined family style, but also ensured that the desire for market leading functionality was respected.

A range fully detailed CAD models were formulated in Pro/Engineer Wildfire, which were refined using both high quality rendering, and physical rapid prototypes. The twin approach ensured that a full picture of both aesthetic and functional considerations was formed. The stereolithography and 3-axis machined prototypes also allowed for performance and conformance testing, which gave confidence that the devices would readily pass official certification.


The range was successfully lanced in 2008 and is fully compatible with with all current Scantronic and Menvier alarm panels. The PIR sensor design remains a consistent and well respected seller within the specialist security systems market.
