Greatly reduces the occurrence of false alarms by inhibiting alarm activity without a person in the
archway. In circumstances where large metal objects, such as luggage or supply carts and x-ray
equipment, pass by or are located near the unit, the sensor automatically inhibits the alarm,
•
Generates a traffic count of the number of persons passing through the detector in both
directions.
(*for
ThruScan
s3/s6
this feature is achieved by a mono sensor under the Control Unit
thus counting in one direction!)
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)
has 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) Operation Channel of the units can be changed for interference free operation. There
are 4 different operation channels available with every ThruScan WTMDs as a Standard Feature.
Synchronization can also be done by using the Synchronization Cable. For this the Synchronization
Cable (optional) must be used.
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 the ON button after these steps have been 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 Shut OFF.
