L768 Room Communicator Unit.
The L768 Room Communicator allows the intercom speech path to be initiated to a room without the room having
called first, extending the capabilities of the Intercall 700 system into warden controlled establishments. The unit is
very simple to use with the desired room selected using the rotary control on the front panel. In addition, general
announcements (such as lunch times etc) can be made from the unit and these are sent into all bedrooms. The L768
must be used in conjunction with L758 displays to show and sound for calls from the rooms.
Announcements can be made to all L752 and L762 Audio call points providing the speech channel is not in use,
including call points which are calling in emergency and attack. Individual Rooms can only be called when they are in
the Reset or Nurse Presence condition. The call points give an attention double bleep to announce the page or intercom
communication. Only L752 and L762 units with batch codes L04xxxx or later are compatible with the Room
Communicator.
To Call and Speak To A Room.
1. Turning the SELECT control clockwise or anticlockwise will scroll
through the rooms on the system. Use this method until the desired
room is showing on the top line. On the example to the left this is
Bedroom 21.
2. With the desired room showing on the top line of the display, press
and release the TALK button. The unit will show PLEASE WAIT
on the lower line of the display while the selected room is contacted.
Before the speech channel opens, a re-assurance double bleep will
sound at the call point and at the Room Communicator.
3. Once the Re-assurance bleep has sounded, the speech channel is
open from the room to the communicator. Press and hold the
TALK button to speak to the room and release to hear the room.
4. When the conversation is complete and you wish to close the
intercom, press and release the Select button. This will reset the
unit and close the speech channel.
5. You may use the SELECT control to select another room as
described in paragraph 1 above, alternatively, the unit will reset to
the default text setting if the select control is not used for 10
seconds.
