VIBRO is an inte1ligent Microprocessor controlled shock sensor.
The sensitivity is autornatica11y set in Leam Mode by the level of a
recognised impact made to the protected area. The number of
impacts i.e. Pu1se COWlt requjred to generate an a1arm is determined
by the number of recognised impacts made in Leam Mode.

Test Mode
A.fter power up the VIBRO goes through a self test for 2 seconds.

Test result indication by LED are as follows:
.Test satisfactory -Several flashes of green light.
.Test fail -No light or constant Red light or short flashes of

Red light.
If test fails -check all connections and power. Repeat power up 3
times. If test still fails replace the wút.

2.

1. Instal1 the VIBRO according to instal1ation procedure.

2. Power up the VIBRO. Wait 2 seconds for se1f test.

3. Choose sensitivity mode (switch 4) before ca1ibrating.

4. Make sure the a1ann system is in Unset mode.

5. Turn ON switch 1 (learn switch) -Red LED will1ight.

6. When the learn switch is turned on, the VIBRO will

automatica11y recognise polarity of the latch voltage.

Wait 2 se-coh~d "stm tapping the area of coverage for

number of pu1ses required -Whi1e red LED is on.

Each va1id tap will change LED colour to Green and then

return to Red (the LED should go to Red before the next pulse

count is registered).

The sensitivity and pulse count are automatica11y determined

by the number and level of impacts made to the area to be

protected at the furthest point from the detector.

10. If a Green 1ight doesn't appear, that area is out of coverage
range at the impact level entered and the tap was "not
counted" -try using high sensitivity or instal1 more VIBROs.

11. Each tap is added to the pulse count, so at the end, the number
of va1id taps will be the pu1se count of the unit.

12. After 15 seconds the Red LED will extinguish and the LED
will flash Green confinning the number of pu1se counts.

13. It is recommended that the learn switch is not returned to the
OFF position until the red LED goes off, and the number of
pulses set is indicated by the number of Green LED flashes.

14. lf you switch off the learn switch before the Red LED goes
off, additiona1 pu1ses may be entered (there is a safety feature
which deletes the last pu1se made, if the time that elapses is
less than 2 seconds).

15. If in the future reca1ibration is needed and the learn switch
has been left in the ON position, switch to OFF for lO
seconds and then turn to ON and proceed to set-up as norma1.

16. To restore default va1ues just move the learn switch to ON for

15 seconds, do not enter any impacts after 15 seconds, the Red
LED will go out and the number of pu1ses will be indicated by
the green LED flashes.

Remove the sensor from its packaging and retain the two
screws and gronunet.

Remove the cover by removing the screw cap, then
unscrewing the single captive screw.

Carefully release the printed circuit board from the base.
Select the intended position for insta11ation, ensuring the

sU1"face is clear of any irregularities.
Move the base to the mounting position and mark the desired

fixing holes, then by using the two self tapping screws fix the
base ( ensU1"e the base is in complete contact with the mounting

surfaces~Jc ~--"~~",,---~~,.~,~~

Carefully push the printedCircilit board onto the base.'. .c

Make the electrica1 connections to the VIBRO as per
connection diagran1 and details. Make sU1"e no power is

applied to the VIBRO while making the connections.
Cable entry to the VIBRO can be gained:­(i) through the hole in the base mounting plate,
(ii) at the end ofthe cover using single cable knock-out,

(iii) using gronunet knockout.

Proceed to TEST/LEARN MODE (see under Ca1ibration

section)
After the unit is ca1ibrated to your satisfaction, select the
required latch mode, replace the cover of the sensor, tighten

the fixing screw. (Do not over tighten) replace screw cap and
check its response to the desired impact.

Gross Attack

The gross attack feature enables fue VIBRO to create an alarm frorn
a single impacto This feature bypasses fue pulse coW1ting in cases
of gross impact detection.

sequentiallatch only).

VIBRO sensors have a non-volatile memory and will retain the
5ettings you have made. even if the 5upply voltage is removed

and sub5equently restored.

Seven wires: Add the above and MEM Set/Unset for normal latch

-also used for all other types of latching.

Eigbt wires: All fue above and COM used for fust to alann and
sequentiallatch. Ensure that fue supply to fue VIBRO is
disconnected before connecting fue communications link.

Sensitivity
Use low sensitivity in a noisy environment -near roads, airports,

factories, etc.
Use high sensitivity in a quiet environment -when you need a large

coverage area.
Walk Test

Use this mode to test the installation.
A green light indicates that the VIBRO recognises an impact.
A red light indicates that enough impacts have been received to
generate an alarm condition, according to the nwnber of impacts and

current calibration of the sensors.

With this feature you can test if the VIBRO is calibrated to your
satisfaction.

Sequential
After an alann occurs in Set mode all coIUlected VIBROs wilI save

their order in the alann sequence. The flfSt 8 w1its will f1ash the red
LED a number of times, according to their alann sequence number .
The rest of the w1its will t1ash the green LED according to their
number as follows: w1it 9 will f1ash the green LED once; w1it lO will
f1ash the green LED twice, etc.

.Factory setting

Reset
All LED alarnl indications will clear 011 setting fue alarnl.
