Paging calls with speech can be accompanied with
alphanumeric messages depending on the speech
programme of the paging desk.
Talk-back
In systems using transceivers, the desk operator can initiate
a speech call to a transceiver holder or vica versa*.
Talk through
The desk operator can link a speech call from one
transceiver holder to another,via the desk,by using the
TALK THROUGH key.If the operator wishes to hear the
conversation the MONITOR key is used and the operator
can also join in the conversation.
Speech reset
This facility can be preprogrammed into the desk,whereby
a special call can be transmitted after the speech call which
will reset the receiver automatically to the stand-by mode.
Group calls
Each receiver in the system can be programmed to respond
to a group call.This can either be achieved by
preprogramming a number of receivers to respond to a
common call number,or by using the “ - “ key (decimal
group call).
In the decimal group call the “ - “ key is used instead of a
call number digit and all receivers with a call number digit
of between 0 and 9 in that call number location will be
paged,i.e. entering 123 - will page receivers 1230 to 1239.
The “ - “ key can be used in up to three locations, paging a
maximum of 1000 receivers as a decimal group call.This is
a useful facility if it is necessary to page fire fighting, first
aid teams etc..
All call
Using a special address it is possible to page all receivers in
the system simultaneously.
Priority facility and emergency interrupt
In multi-desk systems,the desks can be coded on a priority
basis.If a speech call is occupying the line and an
emergency call has to be transmitted,then by pressing the
Priority key you can make an immediate connection to the
system.This of course is assuming that the desk occupying
the line is not of a higher priority status.
Battery saving
Battery saving can be programmed into the desk.With this
facility,the receivers are in the off position until a call is
made to them.A preamble signal is automatically
transmitted before the call to switch the receiver on.
Depending of course on the traffic density,this facility can
extend the life of the receiver batteries by up to 5 times the
normal battery life.This facility is not available on first
generation receivers.
Out of range
The desk is capable of sending an automatic warning signal
to inform the receiver holder that he/she has crossed the
limit of the transmitters range.
Direct calls
Up to 16 direct calls can be preprogrammed into the desk.
These calls can be transmitted by pressing the DIRECT
CALL key followed by one of the hexadecimal keys. This
call can be made to page a single receiver or group of
receivers and it can be followed by speech and / or a
preprogrammed numeric or alphanumeric display message.
Remote contact calls
Up to 8 remote contacts (switches) can be connected to the
desk.These contacts can be used to monitor equipment,
doors etc.,and when the contact is activated, a call will be
sent to a single receiver or group of receivers. The call will
be repeated (repeat time programmable) as long as the
remote contact is activated.
Field alarm (FIAC function)
The desk can be preprogrammed for four different alarm
calls through which selective calls can be made from the
field*.These calls can be followed by a spoken message
from one transceiver holder to another in the field.If the
called receiver is fitted with a talk-back transmitter,then a
two-way conversation is possible using the automatic
TALK-THROUGH facility.
Alarm call
An ALARM key is included for direct transmission of a
preprogrammed call. This call can be made to page a single
receiver or group of receivers and it can be followed by
speech and/or a preprogrammed numeric or alphanumeric
display message.
Absence indication
If the system includes receiver storage racks (such as the
LBB 6150),an absence signal can be sent to the desk from
the rack if an attempt is made to page a receiver which has
been placed in the rack.If a group call is transmitted and a
receiver which is part of the group is in the rack, the
absence signal will not be sent.
* This function may be restricted by local authorities.
