Timings and terms in the event of an alarm
a The personal alarm time begins with the alarm condition (1) and ends
with the triggering of a personal alarm( 4), if the alarm condition has not
already been eliminated or the pre-alarm has been acknowledged (3).
The personal alarm time is the total of the delay time (b) and the
pre-alarm time(c).
b The delay time / waiting time (not applicable to push-button alarm or
warning!) can be programmed individually for all alarm types. It begins
with the recognition of an alarm condition (1) and ends with the begin-
ning of the local pre-alarm signalling (2), if the alarm condition has not
fallen away already.
b The pre-alarm time (not applicable to push-button alarm or warning!)
can be programmed individually for all types of automatic alarms. During
the pre-alarm time, the handset announces the impending alarm. The
carrier of the handset can abort the personal alarm if he/she removes
the alarm condition within the pre-alarm time or acknowledges the
pre-alarm (3).
d The alarm time begins with the transmission of the personal alarm (4) to
the control centre and ends with the alarm being reset (6) on the hand-
set or by a reset command from the control centre.
e According to the DINV VDE V 0825-1 preliminary standard, the reaction
time is the time that elapses between the alarm condition (1) and the
alarm reaching the control centre (5).
