ABSTRACT:
An infrared radiation detector for an intruder alarm has a pyroelectric element comprising a pyroelectric body sandwiched between two electrodes. The element is supported above a header by two leads of a microminiature circuit package. The package is mounted on its back on the header. One lead of the circuit package is electrically connected to the element. The other lead is insulated from the element. A second pyroelectric element may similarly be supported by two leads of the package.
