6.11 ELECTROMAGNETIC NOISE & INTERFERENCE REJECTION/DIRECTIVES
ThruScan
has integrated high quality/high-tech filter circuitry, which substantially eliminates and
rejects spurious magnetic and electrical interference under norms (89/336/EEC) for itself and
mains. As a result of the tests carried Conformity to CE directives, EU European Union Directives for
Safety; EN 60950; Electromagnetic Conformity EN 61000-6-3(emission), EN61000-6-1(immunity)
have been approved.
6.12 MASKING
ThruScan
incorporates special anti-masking programming which guards against dissimilar metal
objects cancelling one another and evading detection. This way false alarms or state of no alarms
are minimised.
ThruScan
sounds an alarm for every area where a metal exists.
6.13 SYNCHRONISATION
If two or more
ThruScan
units need to be placed next to one another in tandem(multiple
operation) the units should be synchronised by a connection cable.
This may also be achieved by changing the frequencies to operate multiple WTMDs side by side
and without cable.
If the cable connection is maintained, one of the WTMD operates as
the
main(master) unit
and
the other as
the slave(satellite)
.
For the synchronization of the units:
1-
Attach the connection cable to the sockets with the
sticker on the side panels.
2-
Choose the main and slave unit
3-
Open the back cover of the control panel of the slave
4-
Turn OFF the switch on the main card on the control panel of the slave
5-
Close the back cover of the control panel of slave.
The WTMDs will operate by pressing ON after these steps taken.
NOTE: When the main WTMD is OFF the slave can not operate
NOTE: If the WTMDs will be used separately again then plug out the synchronisation
cable(phone cable connections-RJ 11/12) from the side panels. Then switch the key of
the slave unit from OFF to ON position.
NOTE: During synchronisation procedures, the WTMDs’ should be shutted OFF.
6.14 ELECTRICAL REQUIREMENTS
Operating voltage:
Over the Switching Power Supply Module 110-220 VAC choice can be
selected 70 – 270 VAC (supply should be well grounded/earthed and the
ground must be in proper electrical NORMs) - 50/60 Hz.
