Abstract

PURPOSE:To test whether or not an alarm device can operate normally under the severest condition by detecting that the voltage of a battery drops from a prescribed threshold voltage. CONSTITUTION:When a low-battery testing switch 8 is closed, a circuit which by-passes a stabilization circuit 3 through a resistance 7 is formed. Then a power supply voltage which is produced by dropping the constant voltage of the circuit 3 or a voltage after the supply of a constant current is released to a level lower than a low-battery threshold voltage Vr, but higher than the final using limit voltage by means of a resistance 7 is supplied to each circuit section. Therefore, a low-battery detection circuit 6 gives a low-battery detecting output to an alarm display circuit 5 and the circuit 5 issues a low-battery alarm. Simultaneously, an operation testing switch 9 is closed and the circuit 5 issues an abnormality alarm based on a false abnormality detecting output when the circuit 5 normally operates in a state where the battery voltage is dropped from the threshold voltage Vr, in order to receives a false abnormality detecting signal.
