Nudge sensor adjustment (Engineer switch 5)
The nudge sensor has 10 stages of adjustment with the factory default set at level 8. The level of sensitivity to impacts
can be set via engineering software switch 5.
Should the owner wish to temporarily exclude the nudge sensor (and movement sensor on the S4 Red and Green) they
can do this by either allowing the system to passive arm as an immobiliser only or by arming the alarm in ferry mode.
Please note:
If the sensitivity of the nudge sensor is reduced to its lower settings the level of impact required to
create a reaction will be very high.
S4 Red and Green
In addition to this on the S4 Red and Green systems the nudge sensor can be turned OFF, WARN-AWAY WITH NO
TRIGGER or TRIGGER AFTER A SELECTED NUMBER OF IMPACTS (BETWEEN 1 AND 5) IN ANY 2 MINUTE
PERIOD. This is done via engineering software switch 8.
S4 Yellow
In the S4 Yellow system the nudge sensor also acts as the movement sensor and therefore cannot be permanently
excluded via software switch 8, however the number of detections required to initiate a full alarm reaction can be adjusted
between 1 and 5 detections within any 2 minute period (see engineer software switch 8a).
Adjusting the sensitivity to impacts
Select software switch 5 by pressing
both
buttons of the remote when you hear 5 beeps when in the engineering software
switch selection table.
The alarm will give a quick triple beep to confirm you are in this section and the LED will flash in groups to signify its
current level of sensing (8 in default).
To increase the sensitivity to impacts press the
Grey
button, to decrease the sensitivity press the
Black
button. Each
time a button is pressed you will hear a beep and the LED will flash in groups to indicate where you are in the range (10
flashes = max, 1 flash = min). If you get to the top or bottom of the adjustment range the beep will not be heard and the
adjustment will stay at the maximum or minimum.
Checking the sensitivity
To test the sensitivity is at the desired level, nudge the machine and a series of beeps will be heard if the impact has been
detected. This test can be carried out repeatedly but please allow 5 seconds between impacts for the sensor to settle. If
the sensitivity is at the desired level press
both
buttons of the remote control to accept. If not adjust the level via the
Black
or
Grey
button and retest until you are satisfied with the level of coverage, then press
both
buttons to accept.
Arm/Disarm tones On/Off (Engineer software switch 6)
To comply with EU regulations the alarm system comes with its arm/disarm tones turned OFF. Should the customer
decide they wish to enable audible arming it is important local regulations are consulted and the customer advised if this
action may leave them in contradiction of local regulations.
To enable the arm/disarm tones, select software switch 6 by pressing both buttons of the remote when you hear 6 beeps
as per the engineering software switch selection table. A triple beep will be heard and the LED will be OFF.
Press the Grey button of the remote to turn the tones ON and the LED will change to ON. IF you wish to turn the tones
OFF, press the Black button of the remote control when software switch 6 has been entered and the LED will be OFF,
indicating the arm/disarm tones have been disabled.
Once the adjustment has been made confirm it by pressing both buttons of the remote to exit switch 6 and return to the
software switch selection.
If the arm/disarm tones are enabled it is still possible for the customer to arm/disarm the system silently on a one-off basis
by pressing the Black button of the remote just prior to pressing the Grey button to Arm/Disarm.
If the arming tones are enabled the system will give an audible tone to coincide with the indicator flashes and if the system
is put into Ferry mode a LOWER tone will be heard as the Black button is pressed within 10 seconds of arming via the
Grey button to confirm movement sensor deletion.
Please note:
The inclusion of arm and disarm indication beeps is strictly forbidden in all EU countries.
