If you have ever wanted a chime feature add-on for your wired alarm system but don't want to buy an extra keypad to accomplish this then the ATW PC-300 is what you can use to get the job done!
The ATW PC-300 is a piezo speaker that can be made to chime using the security system's trigger ouputs and can initiate three different chime sounds depending on the way you hook it up. You will use the PC-300's positive, common(negative), and trigger wires to achieve this hookup.
You can also adjust the volume on the chime so that you can have it as loud or as soft as you'd like. You can click on the 'Hear It' choices below to get a sample of what each chime setting sounds like.
