There are two types of alarms that have the Part No. 3T1815. They both have
three different levels of volume output. There is a difference in how their output
volume is changed.
One alarm has a three position toggle switch on the back with the positions
marked as HIGH, LOW and MED. A change in the position of the toggle will
change the output volume.
