Do you know why most of the battery operated device cannot allow its alarm function goes off too long? Because the aural alarm consumes too much power. In order to keep long run of battery life, the alarm duration is 1 minute or even shorter normally. But it is not long enough to warning people the time is up, particularly for long range countdown. People are impossible to stay near by the timer to waiting for alert. Sometimes he takes tea break or engaged with some other matters.
Our PSA alert system, the power saving alert system, can reduce power consumption significantly. This brings our engineering the possibility of designing the endless aural alarm system.
Most of our alarm devices provide the option of PSA endless alert. If you need it, please request.
