A portable wireless receiver is the heart of the integrated alert system which can be set up to work with the other devices in the ALERT range.
For each warning device you have (see below) you can set a different choice of chimes or flashing lights (or both) for each one.
To start you will need the portable wireless hub with its included easy-to-install doorbell transmitter (works up to 300m/984ft) - so you need never miss a visitor again.
If you need to summon help from family in your home (even from upstairs), you can add the Wireless Call Button, worn on a neck lanyard, and just synchronise it with your hub.
And you need never miss an important phone call or the chance to chat with friends and family if you also add the Wireless Telephone Signaller too.
