Applications • Ceiling mount alarms • Ceiling mount light switch
Features and Benefits • TO-5 metal housing • Different window sizes • Single channel output
Pyroelectric detectors for motion Sensing
Product Description This series of four element “Quad” detectors provides all four elements connected to one common output. This configuration enables specific applications in ceiling mount location when applied with suitable lens or mirror optics designs. Two different window options are provided: Large window or standard rectangular window size. For better EMI protection, the built-in capacitor option is available.
