XCEL series of detectors use a single housing design across the range. Whether wired or radio, standard or pet tolerant, these PIRs provide a consistent appearance throughout the installation. The XCEL PIRs have a specially designed spherical lens that generates five layered beams, combined with a dual element sensor to deliver superior detection and catch performance. The PIRs are certified to all EN50131 standards, with the radio technology field proven over many years.
