Harlow Council – Using Safe Sockets to ensure alarm calls are raised

“The Safe Socket gives us ultimate reliability; we know we’ve done everything we can to protect the people we support. They give tremendous peace of mind to our team and to the people using our Careline service.”

Viv Hales, Supported Housing Manager, Harlow Council

The challenge

Telephone lines to our homes are in increasing demand, with multiple telephones, broadband hubs and television receivers all sharing the line. As Lifeline home units provide emergency support, they must be able to raise an alarm on the telephone line even if the line is in use by another device.

How are community alarm and telecare services using the Safe Socket™ to ensure that alarm calls are raised even though the telephone line is in use, ensuring residents are protected?

What we did

The Safe Socket enables the Lifeline home unit to seize the telephone line in the event of an alarm call. The Lifeline plugs directly into the master telephone socket, and all other devices using the same line are connected to the telephone line via a Safe Socket. When an alarm is raised from the Lifeline, it detects the telephone line is in use and signals to the Safe Sockets to automatically cut the line to the connected telephone device. This frees the telephone line for the Lifeline to redial and raise an alarm call.

This means that if a telephone has been left off the hook, or the line is in use by another device, an alarm call will always be raised at the monitoring centre.


The Safe Socket solution provides extra reassurance that help will be on hand in the event of an emergency.

Safe Sockets are compatible with all Lifeline home units, and are easy to install and remove as required. The Safe Socket provides a cost-effective, quick and nonintrusive alternative to rewiring in properties to ensure that the Lifeline unit is directly connected to the BT landline socket.
