Battery-powered alarm
In the present invention, a power supply route to the heater resistor (2b) of a gas sensor (2) is configured from the two routes that are: a route supplying power from a boost circuit (12) via a switch (SW1); and a route supplying power from a battery (1) via a switch (SW4). A control circuit (11) c...

| description | In the present invention, a power supply route to the heater resistor (2b) of a gas sensor (2) is configured from the two routes that are: a route supplying power from a boost circuit (12) via a switch (SW1); and a route supplying power from a battery (1) via a switch (SW4). A control circuit (11) controls switch (SW4) ON while the battery (1) voltage is normal, applying the battery voltage of the battery (1) to the heater resistor (2b), and when the battery (1) voltage has decreased at the end of the battery use life below a predetermined threshold, controls switch (SW1) ON, applying the boosted voltage of the boost circuit (12) to the heater resistor (2b). |
