Safe Socket

As Tunstall home units provide emergency support they must be able to raise an alarm on the telephone line even when another telephone within the property is being used or has accidentally been left off hook.

Until now the only way to achieve this was to rewire all extension phones via the telephone socket in the home unit to allow the home unit to seize the telephone line. However this can involve a considerable amount of rewiring particularly if the property has more than one telephone device sharing the telephone line.

This is becoming an increasingly common occurrence with people using multiple telephones, sky television receivers etc all on one line. The Safe Socket™ is a new concept to ensure that alarm calls are raised even though the telephone line is in use. It allows the home unit to seize the phone line from other connected devices on the same line (i.e. extension phone, computer, fax machine, satellite receiver etc).

If Safe Sockets are fitted and an extension telephone is in use or offhook, the Tunstall home unit’s first alarm call attempt will detect that the line is unavailable. The home unit will then release the line (exchange) which signals to the Safe Sockets to disconnect the line to the in use or off-hook telephone. This then releases the telephone line for the home unit’s second dial attempt which will go through successfully.
