This type of alarm calls can be addressed to one or many CU’s.

This type of alarm calls can be addressed to single or multiline CU’s. Any type of base station activities

relay is activated and the alarm beep sounds in the loudspeaker.

Alarm inputs

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.
