Pyroelectric Four-Element Detectors
For Ceiling-Mount
LHi 1128, PYQ 1398, PYQ 1348 – Single-Output “Quad” Pyro
Applications • Ceiling-Mount Alarms • Ceiling-Mount Light Switches
Features and Benefits • TO-5 metal housing • Different window sizes • Single Channel output
Product Description In this series of four-element “Quad” Detectors, all four elements are connected to one common output. This configuration enables specific applications in ceiling-mount locations, when applied with suitable lens or mirror optics designs. Two different window options are provided: a large window or standard, rectangular window size. Various element polarities are available upon request. For better EMI protection, the built-in capacitor option is available.
