Abstract
A glassbreak detector or motion detector includes circuitry responsive to an installation process. Data concerning the installation process can be automatically stored in non-volatile memory. The stored data can be retrieved as part of an after-installation review.
Claims15
A detector comprising:
- a housing;
- an environmental condition sensor carried by the housing;
- and
- control circuits coupled to the environmental condition sensor;
- a program, debug and test interface coupled to the control circuits;
- and
- non-volatile memory, where the control circuits acquire input signals from the environmental condition sensor and store installation information pertinent to the detector's setup and validation steps performed at a time of installation of the detector including installation verification parameters related at least to range testing of the environmental condition sensor, the installation information is loaded into storage circuits of the non-volatile memory coupled to the control circuits, wherein when the detector is powered up, it checks to see if an installation flag data bit is set, where the installation flag data bit is set when the detector is first put into test mode and wherein the installation information is detected and stored in real time for later retrieval through the program debug and test interface.

A method comprising:
- providing an environmental condition detector;
- control circuits of the environmental condition detector setting an installation flag data bit when first placed in test mode and obtaining and storing real-time data on storage circuits of the environmental condition detector, the real-time data pertains to setup and validation steps performed on the environmental condition detector at a time of installation including at least range testing of the environmental condition detector;
- and
- subsequently retrieving the stored data from the storage circuits through a program, debug and test interface to determine if the setup and validation steps were performed properly.
