Clarity AlertMaster AL10 Notification System with AL12 Receiver and Doorbell for Two Rooms

The all new, redesigned Clarity AlertMaster® AL10 Notification System is a complete alerting system that alerts you to the telephone, alarm clock and doorbell. This system can be expanded by adding additional transmitters for notification of sound or motion, or purchase additional receivers to be notified in more rooms. The AL10 is an ideal solution for those with a moderate-to-severe hearing loss who want to be notified in more than one room.

Don't worry, the new AlertMaster will work with all existing AlertMaster products, so there's no need to give away your old system. The new AL10 features a sleeker design, plus larger display and visual indicators. The AL10 also has different flashing patterns so you can distinguish between the door, telephone/VP, alarm clock, or one of the other optional transmitters that can be added to this system.

What else do I need to make this work?
This is a complete system that comes with all the items needed for door, alarm clock and phone notification in one room. By adding optional transmitters and/or receivers, you can customize the AL10 system to fit all of your household notification needs.
