9.14 Input Verified Method
[TM5151] Alarm verifica-
tion of inputs
This menu function enables an alarm verification of inputs to be programmed. This function enables the
triggering of burglar alarms to be filtered. Two methods are available for this purpose:
z Combination of groups (A+B combination)
z Filtering of inputs (pulse counter)
Only one method can be used per partition. The alarm verification is activated only On full set:.
9.14.1 Combined Inputs
Combination A+B In this case, the inputs are assigned to group A or group B. A burglar alarm is not triggered until at least one
input of each group has triggered. There is only one A+B group pair per partition. As many inputs as required
can be assigned to the groups.
First group A In addition, it can also be determined whether the group A has to be first triggered or whether the sequence
of triggering is unimportant.
Time window The triggering of both groups must, of course, take place within a specific time window. Any time between 1
minute and 30 minutes can be programmed.
9.14.2 Pulse Counter
Pulse counter With the pulse counter, each input is individually filtered. It therefore requires several individual triggering to
trigger the alarm.
Time continuous pulse So that in the event of a continuous triggering of the input an alarm is still triggered, the time continuous
pulse is programmed. After this time has elapsed, even if the number of pulses has not been reached, an
alarm is still triggered. This time applies to all inputs of the complete partition programmed on pulse counters.
A time period of 5 to 30 seconds can be programmed.
Time window A time window is started on the first pulse. The programmed number of pulses must then take place within
this time. If the number of pulses is not reached by the end of the time window, the pulse counter is reset to
0. The time window applies to all inputs of the complete partition programmed to pulse counters. A time
period of from 10 to 180 seconds can be programmed.
9.15 Bypass Mode
Bypass Mode This parameter describes the condition when a forced setting can be performed:
ONE = Only one input line can be bypassed
Only one input line can be bypassed in one setting cycle of the assign partition. After an unset has
been carried out, setting can only take place again after an engineer reset.(previously VdS forced
setting).
ALL = Up to 50 % of input lines can be bypassed
Several lines of a partition can be bypassed for one setting cycle, up to a maximum of 50 % of the
lines
