Passive emergency call function
("Passive emergency")
The passive emergency call function is used to summon help
if the person involved in an accident is no longer capable of
triggering an active emergency call. This function is only useful
if people located in the vicinity can be alerted via a connected
loud horn or if an emergency call TD is installed to alert other
assistance-providing persons. All active commands are ended
and no other commands accepted (command lock).
The passive "Emergency call trigger" is set off automatically and
involuntarily if:
The transmitter has not been operated over a given period
of time (factory setting: 180 s) and the receiver has not
received anymore commands
(range monitoring)
The transmitter is not moved anymore (factory setting:
180 s)
(acceleration monitoring)
The transmitter is tilted at a particular angle (factory set-
ting: greater than 45°, 180 s)
(position monitoring)
The function "Passive emergency" is switched off on delivery
(factory settings). You must switch on this function if it is requi-
red (see operations / passive emergency).
The "Siren" output is not monitored upon delivery
(factory setting); but it can be parameterized to be
monitored.
