Incoming priority status to CU(s)
Priority status calls can be addressed to one or more CU’s.
They are handled whether the base is busy or not.
The calling mobiles id, route and status is queued in the called CU’s.
Incoming alarm call from mobile alarm transmitter
This type of alarm calls can be addressed to one or many CU’s.
The transmitters id and route are queued in the alarm queue in the called CU’s. The alarm relay in the
called CU’s is activated and the alarm beep sounds in the loudspeaker. Alarm calls are handled even if
the base is occupied.
Incoming alarm call with speech
This type of alarm calls can be addressed to single or multiline CU’s. Any type of base station activities
is cleared down. The calling mobile's id, status and route are shown in the called CU's display, the alarm
relay is activated and the alarm beep sounds in the loudspeaker.
The not called CU’s indicate LINE BUSY.
If multiline, when one of the called CU’s answer the call, the other CU’s indicate LINE BUSY, but stay
with the loudspeaker open.
Alarm inputs
When any of the alarm inputs is activated a personality-specified code is queued in all the CU’s.
The alarm relay is activated and the alarm beep sounds in the loudspeaker.
(
NOTE
there are only 2 inputs for LP210)
Alarm beep and relay
The alarm beep and the alarm relay are activated when an alarm call is received. The beep and the
relay are inactivated as soon as any key is pressed. If it is an alarm call with speech, the beep and the
relay are inactivated also when any of the called CU’s answer the call.
Repeater traffic over the base
If repeater traffic is enabled and the base isn't occupied, a mobile can call another mobile, or group of
mobiles. If the called mobile or group of mobiles is specified in the personality, connection is established
and the CU's indicate LINE BUSY.
All CU’s can listen to the call, by opening their loudspeaker, or talk, by pressing PTT.
Any CU can take control of the call by pressing |Listen| (with any route chosen). The mobiles stay
connected. If |-/-| is pressed, a DISCON telegram is transmitted and repeater traffic is cleared down.
If |Listen| is pressed and |CLD| has not been pressed, the mobile call continues.
Any CU can disable repeater traffic while a mobile-mobile call is in progress. In that case a DISCON-
telegram is transmitted and the call is cleared down.
