Calls
from patients or staff are identified by the HUB and translated
into a full text signal that is then transmitted via the same
two wires to the display units. The HUB can also relay the
text messages into an optional alphanumeric radio pager to
send messages to pocket pagers. The message, which each call
point generates, can be changed by staff if required.
Patients'
names can be added to their room numbers, for example. Staff
can use the units to generate an "assistance" call;
this is easily identified by staff as it has a different pulsed
tone. They can also generate a "crash" call when
extremely urgent help is required.
