There seems to be a lot of alarm detections occurring, more than we want or expected. Why
is this?
Before implementing a metal detector into your security, one must have a plan as to how the
equipment is going to best work for them. The best way is to consult who is going to be
monitoring the unit and what is the purpose of the unit. For example, if you are looking to
catch people stealing small computer IC chips in their pockets, you are going to need a high
sensitivity to detect them. One must have a plan as to which items are needed to be put aside
before walking through. If you are not sure, or would like a product specialist to assist creating
a plan, feel free to contact us at (815) 467-6464.
The passerby units are not adjusting or are continuously increasing. What should I do?
The black circular discs on the inside of the panels are the infrared sensors. These pick up
when a person walks through the unit. If the unit is not picking up the passerbys, the sensors
may have fingerprints or dirt on them. With a cloth towel with rubbing alcohol or window
cleaner, rub around the sensor to clean. Also, please check and make sure that the cables are
securely fastened to the metal detector leg panels and PC board. If this connection is loose,
the unit may not work.
