TRAFFIC LIGHTS

Location of the Traffic lights may vary as per different models. At the

entrance part of the Two Side Panels (ThruScan s9), at the Entrance Part

of the Control Unit (ThruScan sX/sXWP/s15-i/sX-i), under the Control Unit

(ThruScan

s3/s6). These bi-color lights indicate if the archway is ready to

control for passage.

 The green light indicates “Walk”.

 The red light indicates “Stop”.

ZONE(INDICATOR)- LIGHTS (*)

ThruScan Walk-Through Metal Detectors has Zone Display LEDs

(LED ARRAY) on Both Side Panels continuously from the bottom

part of the detection area to the top. These LED ARRAYs helps the

operators pinpoint the detected metal objects throughout the

WTMD Passage.

(*)

ThruScan

s3/s6 do not have this feature but Graphic Zone Leds

on control panel.

WARNING: In case of a power cut,

ThruScan

continues

operation with its internal power supply. Zone-lights will

shut down automatically to save energy after a certain

period of time during power failure. Graphic Display on

Control Panel will indicate the location of threat zone.

VARIOUS ALARMS

Both the supervisor and the operator should be familiar with the

ThruScan’s audio & visual alarms.

The unit will generate an alarm condition to indicate that a sufficient

volume of metal (according to the program and sensitivity settings)

has been detected; Special built-in filtering circuits help to suppress

excess electronic noise signals from a variety of sources, including

X-ray monitors, horizontal synchronisation and closed-circuit

television/CCTV, etc..

Metal detectors sometimes generate false alarms, triggered by nearby metal objects or interference

from electrical or mechanical environmental noise from large motors, computers, fluorescent

lighting or other sources. The ThruScan’s infrared sensors are a feature that helps to minimise the

audible false alarms by ensuring that an alarm activates only if a person passes through the

archway.

A false source may trigger the alarm rarely such as a person pass and bump the archway also.

CAUTION! The operator must never dismiss a false alarm since there may be the

possibility of a professional terrorist person to create a false alarm by bumping and

thus creating confusion.
