Using the L768 Room Communicator.
The L768 Room Communicator allows the intercom speech path to be initiated to a Call Point without the Call Point
having called first. The unit is very simple to use with the desired room selected using the rotary control on the front
panel. General announcements (such as lunch times etc) can also 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.
To call and speak to a room.
Turning the SELECT control (Shown on the left) clockwise or anticlockwise will scroll
through all available call points on the system. You may contact any call point which is
not currently calling. Rooms can be contacted regardless of other system activity,
providing the speech channel is not in use. While the rooms are being contacted, the call
point buttons are inactive.
Selecting the desired room.
Turn the Select control until the desired room is showing on the top line of the display. In
the example shown on the left BEDROOM 21 is being selected.
The privacy bleep.
With the desired room showing on the top line, press and release the TALK button as
shown on the left. There will be a small delay while the room is contacted before the
privacy bleep is sounded at the call point and at the Room Communicator. While the
room is contacted, the screen will show PLEASE WAIT on the lower line of the display.
Opening the speech channel.
After the privacy bleep has sounded, the intercom channel will be open and the call point
will be able to speak to the Room Communicator. Press and hold the TALK button while
speaking to the room and release to allow the room to speak. While the speech channel is
open the words “Speech Open” will be showing on the lower line of the display.
Closing the speech channel.
When the conversation is complete, the intercom may be closed by pressing the SELECT
button once. This will reset the unit and close the intercom channel.
Selecting another room.
Once the speech channel has been closed and the room is again showing on the top line
of the display, another room can be selected using the SELECT control as previously
described. Alternatively, if the SELECT control is not operated for 10 seconds, the unit
will return to the default text (Intercall 700)
Broadcast or Tannoy messages to all rooms.
The room Communicator can also be used to send common messages to all Call Points.
Call Points can be contacted regardless of other system activity, providing the speech
channel is not in use.
Selecting tannoy.
Turning the SELECT control (Shown on the left) clockwise or anticlockwise will scroll
through the rooms on the system. Use this method until TANNOY ALL ROOMS is
shown on the LCD display.
Using the Tannoy.
With TANNOY ALL ROOMS showing on the display, press and HOLD DOWN the
TALK button. There will be a small delay while the rooms are contacted before the
privacy bleep is sounded in the room and at the Room Communicator. While the room is
being contacted, the screen will show PLEASE WAIT on the lower line of the display.
Now make the announcement and release the TALK button. It is not possible for the
rooms to speak back to the Room Controller in this mode. While the rooms are being
contacted, the call point buttons are inactive.
