NESS D8 (V4.7) CONTROL PANEL – INSTALLER MANUAL
VIBRATION SENSITIVITY
Each zone has individually adjustable sensitivity for connection of Nessensor
Vibration Sensors.
Zone sensitivity is adjusted by toggling zones ON in options P30E to P38E.
P30E, Normal Sensitivity– vibration analyser disabled. This is used for normal
alarm devices. Zone response time, 200ms.
P31–38E are the options for the 8 levels of vibration sensitivities. P31E is the most
sensitive setting.
PROGRAMMING SEQUENCE:
P [30–38] E zones are displayed [Zone No] E
EXAMPLE: To program zones 2 and 3 to be Medium Sensitivity:
P34E 2E 3E the keypad display will show zone lights 2 & 3 to be ON
P30E – P38E
PROGRAM MODE LEVEL:
Installer, Remote by PC
FACTORY DEFAULT:
Normal sensitivity.
P30E, all zones = ON
NOTES:
• Sensitivity can be individually
programmed for each zone.
• Zones are allocated to one sensitivity
level at any one time. Turning a zone ON
in a sensitivity level, turns the zone OFF in
any other sensitivity level.
• To revert zone sensitivity back to Normal.
Turn the required zone/s ON at Option 30.
• Avoid using P31 and P38 sensitivity
– they are provided as a guide to the
upper and lower limits.
• USING NESSENSORS.
Nessensors are sensitive to high fre quen -
cies and in sen si tive to low fre quen cies.
There fore it is not nec es sary to apply
much force to the pro tect ed structure,
rather a very rap id succession of blows.
The sensitivity has been cor rect ly ad-
just ed when a single blow ap plied with
a soft ob ject (e.g. by hand) does not
cause an alarm whereas a rap id series
of blows (using a metal ob ject such as a
screw driv er blade) will cause an alarm.

In addition to zone sensitivity adjustment,
the overall sensitivity of the Nesssensor
can be adjusted by rotating the body of
the Nesssensor within its bracket.
The bracket must always be mounted
horizontally and the arrow must point
up for any required setting.
