CO END OF LIFE TIMING CIRCUIT
First Claim
1. A method for indicating the end of a life cycle of a device, comprising:
- installing a device communicating with a control device;
instructing a user to enter a specified date;
entering the specified date in a programmable timing mechanism of the control device;
calculating a life cycle time period beginning from the specified date; and
initiating an end of life cycle indicator after the life cycle time period has elapsed.

Abstract
A system for indicating an end of a life cycle time period for a device which may include a sensor device or detector for measuring an environmental condition. A control device communicates with the device and includes a programmable timing mechanism for measuring a life cycle time period. The control device initiates an end of life cycle indicator such as a fault message after the life cycle time period has elapsed. The life cycle time period may be measured from a date of manufacture of the device. The life cycle time period may also be measured from a date of installation of the device when the date of manufacture of the sensor device is unknown. In the case of sensor devices or detectors an environmental condition for measuring by the detector may include carbon monoxide levels in an enclosed area where the device is a respective carbon monoxide detector.

8. A control device, comprising:
-
a control device communicating with at least one remote device, and the control device including a programmable timing mechanism including a computer program embodied in a computer readable medium readable by a computer, and the programmable timing mechanism measuring a life cycle time period of the remote device and initiating an end of life cycle indicator after the life cycle time period has elapsed; and a date of manufacture of the remote device entered into the computer program for calculating the life cycle time period measured from the date of manufacture or being measured from a date of installation of the remote device automatically entered by the computer program when the date of manufacture is not entered. - View Dependent Claims (9, 10)
