Abstract
An oscillator supplies clock pulses to a counter which also has a preselected time applied thereto and arming means are initiated when the count reaches the preselected time. Checking means are utilized throughout the circuitry to provide failsafe checking of each critical circuit with the arming circuit being deactivated if an error is detected. The entire circuit is incorporated in a single IC for energy and space conservation.
