Abstract

An alarm device (1) has a circuit (10) with a microcontroller (11) which activates a green LED (4) to indicate normal operation, a yellow LED (6) to indicate if there is a fault, and a red LED (5) to indicate an alert arising from carbon monoxide concentration exceeding a volt. If the user presses a test/hush button (3) the microcontroller indicates the peak concentration since a memory was last reset. Continuing to press the button causes the memory to be reset. This provides peace of mind to the user. <IMAGE>
