1. A speech emergency call system comprising a central control unit;
- a system cable connected to the central control unit;
a plurality of speech modules each capable of handling two-way speech communication, all the speech modules being connected in parallel to the central control unit by the system cable;
each speech module having an associated call initiator and means for transmitting a unique identity code from that speech module to the central control unit when a call is initiated from that speech module;
a master unit comprising means whereby it is connectable to the system cable, alerting means capable of response to a call initiated from a speech module and two-way speech communication control means;
an interface unit connected between the central control unit and a line of the public telephone network, the interface unit including autodialling means for automatically dialling telephone number;
the master unit and the central control unit including emergency call means operative to cause an outgoing call to be autodialled over the public telephone network and for the master unit to be placed in two-way speech communication once the outgoing call has been connected.

Abstract
A sheltered housing scheme communications system is provided. The system includes a master unit carried by a warden which is able to receive and initiate outside telephone calls. This is accomplished by inserting the master unit into a system cable which controls an auto dialer. The auto dialer is capable of dialing a non-preprogrammed telephone number by operation of the master unit. The master unit also functions to indicate its availability to answer an incoming call to the central control unit.

each speech module having an associated call initiator and means for transmitting a unique identity code from that speech module to the central control unit when a call is initiated from that speech module;
a plurality of master units, each having a unique distinguishing code, each master unit comprising means whereby it is connectable to the system cable, alerting means capable of response to a call initiated from a speech module and two-way speech communication control means;
the control unit including recognition means for recognising the identity code of any calling speech module, and routing means for initially routing all calls from a first group of speech modules as recognized by said recognition means to a first one of said master units, and for intially routing all calls from a second group of speech modules as recognized by said recognition means to a second one of said master units;
an interface unit connected between the central control unit and a line of the public telephone network, the interface unit including autodial means for automatically dialling a telephone number;
each master unit and the central control unit including emergency call means operative to cause an outgoing call to be autodialled over the public telephone network and for the master unit to be placed in two-way speech communication once the outgoing call has been connected; and
the central control unit including means responsive to an incoming call from the public telephone network and for routing that call to any selected master unit, each master unit having means enabling it to receive an incoming call.
