ABSTRACT A new improved combustion - smoke detection device including means for insuring that the device is operable with the optimum sensitivity that is substantially constant while initial power source has diminished. Another feature is that the present invention has a visible indication of a low-primary energy level, and an audible indication of a low-secondary level. Another primary feature of the present invention is that it is a re- chargeable system, and has the provisions of a means for testing the operation of the system with a manually actuated switch, and a means of a temporary signal producing delay or "silence" circuit that is automatically de-activated after a predetermined time period. Another feature of the invention is that the circuitry for monitoring of energy level, and signal delay is of an energy efficient design extending the power source life. Another feature of the present invention is that the preferred embodiment is mounted on a wall within reach of users for ease of control over its functions.
