T Sensitivity: This trimmer sets the ‘Single Shock’ threshold. The select-
ed value — minimum 20 (100 ms), maximum 1 (5 ms) — will determine the
‘Shock’ impact the zone will allow before signalling violation. Set 1 for max-
imum sensitivity.

T Pulse: This trimmer sets the ‘Pulse’ threshold. The selected value will
determine the number of ‘Shocks’ the zone will allow before signalling viola-
tion. Therefore, if the trimmer is positioned on Disable, the corresponding
zone will be completely insensitive to Pulses.
For example, a zone with the ‘Sensitivity’ threshold of 10 and ‘Pulse’
threshold of 5 will generate an Alarm when:
a) it receives a single Pulse that exceeds the Sensitivity threshold of 10;
b) it receives 5 Pulses of low Sensitivity within 30 seconds.
NOTE: If you assign N.C. Balancing (Normally Closed) to a Vibration
Zone, Wire cutting will not be signalled.
z Roller Blind (Roll.Bl.) -This attribute must be assigned to Zones used for
Roller blind contacts. There are two trimmers for sensitivity adjustment in
the ‘Roller Blind’ section.

TT
TPulse: This trimmer regulates the ‘Pulse’ threshold (1 through 5). The
selected value will determine the number of ‘Shocks’ that the zone will allow
before signalling violation. Therefore, if Disable is selected, the correspond-
ing zone will be completely insensitive to Pulses.

T
Time - This trimmer regulates the ‘Time’ window. The selected value will
determine the ‘Pulse’ threshold time (i.e. the time allowed for the Pulse coun-
ter to reach the programmed threshold).
For example, a zone with a ‘Pulse’ threshold of 4 and a ‘Time’ window of 2
minutes, will signal violation when its contact generates 4 Pulses within 2 min-
utes.
If less pulses than the programmed ‘Pulse’ threshold are generated dur-
ing the ‘Time’ window, the zone will not signal violation, but will refresh
the window and carry forward the memorized number of pulses minus
one (e.g. 3 pulses memorized = 2 pulses carried forward). The window
will be refreshed until there are no pulses to carry forward, at which
point, the ‘Pulse’ threshold and ‘Time’ window will reset.
If the trimmer is positioned on ‘repetitive’, the number of pulses (if less
pulses than the programmed ‘Pulse’ threshold) will be stored indefinitely.
In all cases, the ‘Pulse’ threshold will reset automatically each time the Con-
trol panel disarms.
NOTE: Tamper cannot be signalled if N.C. Balancing (Normally Closed)
is assigned to the Roller Blind Zone.
