AlertMaster CL-AL10K Notification System by Clarity

The all new, redesigned Clarity AlertMaster® AL10™ Notification System is a complete alerting system that alerts you to the telephone, alarm clock and door knock. This system can be expanded by adding additional transmitters for notification of sound or motion. The AL10 is an ideal solution for those with a moderate-to-severe hearing loss. One year warranty.

By adding optional transmitters, you can also be alerted to: your baby crying (AMER-AMBX)
the motion detector being triggered, letting you know someone has entered your home (AMER-AMSX)
any audible warning devices within 80 feet of unit being activated (AMER-AMAX)

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