Stay aware when a door, window, or cabinet opens with an entry notification system designed for people who are deaf, hard of hearing, or living with mild to profound hearing loss. Loud sound, bright flashes, and strong vibrations help ensure you never miss important activity in your home.

This preassembled bundle includes the Magnetic Switch, Telephone Transmitter, Alarm Clock Receiver, and Bed Shaker. Setup is quick and requires no Wi-Fi or pairing. Everything works right out of the box.

The Magnetic Switch triggers when two connected surfaces separate, such as when a door, window, drawer, or cabinet is opened. It plugs directly into the Telephone Transmitter and is ideal for entryways, medicine cabinets, refrigerators, or areas where extra monitoring is needed for safety, children, or individuals with dementia.

The Telephone Transmitter sends a wireless signal to the Alarm Clock Receiver when the Magnetic Switch is activated. It also includes additional input ports for connecting optional accessories like contact mats or compatible NOAA weather alert devices that use 3.5 mm or 2.5 mm trigger cables.

The Alarm Clock Receiver alerts you with your choice of loud sound, bright flashes, or powerful vibrations from the included Bed Shaker. Color-coded LED indicators make it easy to identify the source of the alert at a glance.

This bundle can be used on its own or as part of the larger Bellman Alerting System. It is fully expandable. Add additional transmitters to detect loud sounds, doorbell notifications, or smoke alarms at any time with no extra setup.
