First Claim
Patent Images
1. An alarm device for detecting radiation and/or air pollutants, the alarm having:
- a control circuit including a microcontroller configured to monitor preselected alarm parameters;
memory means for storing data representing said parameters; and
a detachable disabling feature for placing the control circuit into a shutdown mode for transportation or storage;
wherein said microcontroller has an input/output means connectable by said disabling feature to a preselected voltage level for switching said control circuit between an operational mode and said shutdown mode,and wherein the input/output means is also connectable, with said disabling feature detached, to an external processing means for enabling downloading and display of said data.

Abstract
An alarm for detecting radiation and/or air pollutants such as smoke, carbon monoxide or the like has a control circuit (11) including a microcontroller (12) configured to monitor preselected alarm parameters, and memory means (30, 36, 40) for storing data representing said parameters. The microcontroller (12) has an input/output means (3) connectible both to a preselected voltage level for switching said control circuit between an operational mode and a shutdown mode and to an external processing means for enabling downloading and display of said data.

13. A method of operating an alarm device for detecting radiation and/or air pollutants, the alarm having a control circuit including a microcontroller configured to monitor preselected alarm parameters and a detachable disabling feature for placing said control circuit into a shutdown mode for transportation or storage, said microcontroller having an input/output means connectable by said disabling feature to a preselected voltage level for switching said control circuit between an operational mode and said shutdown mode and connectable, with said disabling feature detached, to an external processing means for enabling downloading and display of data representing said monitored alarm parameters, the method comprising the steps of:
-
(a) checking the presence or absence of said preselected voltage level; and (b) in response to said check indicating that the alarm is in an operating mode, transmitting said data to said input/output means for downloading to said external processing means. - View Dependent Claims (14, 15, 16, 17, 18, 19)
