Abstract (en)
An alarm notification device having an optimized power draw function in which it a voltage on a supply line to which it is connected is sensed and then used to proactively determine a current to be drawn by the device. In this way, the current drawn by the device on start up can be controlled to avoid an undesirable current surge or overshoot. Moreover, the device may be sensitive to an under voltage condition on the supply line and adapt its operation in order to reduce or eliminate a risk of the supply line becoming catastrophically overloaded. The device may be arranged to provide an alert that indicates the presence of the under voltage condition.
