1.INTRODUCTION TO DFMD:We are the leading manufacturer, supplier of Door Frame Metal Detector. A metal detector is an electronic instrument which detects the presence of metal. Metal detectors are useful for finding metal hidden within objects, or metal objects buried underground. A Door Frame Metal Detector (DFMD) as the name suggests is a metal detector fitted in a door to detect metal that may be hidden on the body of the person passing through this door. This is also known as a “walk through” metal detector. These are used for security screening at access points in prisons, courthouses, and at airports to detect concealed metal weapons on a person’s body.The simplest form of a metal detector consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field. If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces a magnetic field of its own.The biggest technical change in detectors was the development of the induction-balance system. This system involves two coils that are electrically balanced. When metal is introduced to their vicinity, they would become unbalanced. What allowed detectors to discriminate between metals was the fact that every metal has a different phase response when exposed to alternating current.
Security Screening: Metal detector technology was adapted to screen airline passengers. Mining metal detectors housed in a large cylindrical pipe were used to make a commercial walk-through security detector. This eventually led to the development of the rectangular gantry, now standard at airports. Both alternating current and pulse systems are used, and the design of the coils and the electronics has moved forward to improve the discrimination of these systems. It is possible to indicate the approximate height of the metal object above the ground, enabling security personnel to more rapidly locate the source of the signal. Smaller hands held metal detectors are then used to locate a metal object on a person more precisely. DFMD’s are designed for high throughput with fewer unnecessary alarms. Targeted objects, such as guns and knives, are consistently and accurately detected, while personal items such as keys, coins, belt buckles and eyeglasses can pass through without causing an alarm.Most DFMD’s have phase sensitive detection circuits, that allow the user to enhance the sensitivity for certain group of metals and reduce it for others. DFMD’s are designed to detect both Ferrous & Non Ferrous Metals. With higher sensitivity they can be used in the Jewellery manufacturing units to protect against pilferage. High Sensitivity DFMD’s are designed specifically for detecting small ferrous and non-ferrous items, such as disposable prison razors, a piece of razor blade, metal shanks, handcuff keys, detonator caps, jewellery, coins, microprocessor and memory chips. Use of such DFMD’s increases safety in prisons and jails by efficiently detecting small metal objects that can be used as weapons, even when they are hidden in body cavities. They are also deployed in manufacturing and distribution facilities to protect small, valuable assets.

4.APPLICATIONS OF DFMD:
•Factors to consider when evaluating a DFMD.
Uniform Detection: It is important to select a detector that gives uniform detection throughout the entire interrogation region. The detection response from a poorly designed conventional detector will not be linear. High sensitivity hot spots and low sensitivity regions known as dead spots may be present within different regions of the detection field. The detection response from a particular metal object will vary as it is carried through different sectors of the gate.
•Electrical and electromagnetic interference: They can play havoc with their performance and often render them unusable. Interference rejection is what separates quality detectors from others. Quality detectors utilize highly efficient noise inhibition software algorithms. Noise originates from a variety of sources; flickering fluorescent light tubes, computer monitors, photocopiers, two-way radios, etc. The level of ambient noise will vary from location to location. It is advisable to test the DFMD in the location where it will eventually be installed.
•Continuously active detection: Always select a detector that is continuously active. At no time should the detection circuitry be deactivated. Under no circumstances should a non-continuously active DFMD be installed in an unmanned automatic entry door system.
•Metal types: For both weapons screening and pilferage prevention the detector must be capable of efficiently detecting a variety of metals in a single operating program.
•Object transit speed & Orientation: Irrespective of whether the target object is carried very slowly, quickly or tossed through the detector it should always be detected. It should also be possible to detect the target irrespective of its orientation.
5.WHAT IS THE ROLE OF DFMD:
5.1.What is DFMD? A Door Frame Metal Detector (DFMD) as the name suggests is a metal detector fitted in a door to detect metal that may be hidden on the body of the person passing through this door.
5.2.Description of DFMD? DFMD is just like a door with two walls and one roof which almost looks like a entrance door through which a person’s move. There are Sensors attached to the Walls of DFMD. We can see a LCD Screen at the top of the DFMD which displays Either Walk / Stop. Beside the LCD Screen we can see different Buttons like Power Switch, Sensor, and Volume etc. One side of LCD Screen it has powerswitch which can ON / OFF and Led’s Which indicates levels such as (L1, L2, L3). At the other side of LCD Screen we can see Sensitivity switch which can increase / decrease the sensitivity, Volume which can adjust and Alarm indicated LED. These all help the DFMD to work properly.
5.3.Types of DFMD?
There are Two models in DFMD, they are:
•Single zone DFMD
•Multi-zone DFMD provide multi zone detection A Multi zone DFMD will identify whether the target is on the left side or right side of the person. If an individual walks through the DFMD with a concealed weapon located at their ankles, both the single and multi zone DFMD will locate the target. The difference between the Single zone DFMD and Multi-zone DFMD is that the multi zone detector will be able to identify the location of the target, on either the left or right side of the individual.
Single Zone DFMD:In single zone DFMD, it detects all metals but it doesn’t recognize where the target is located.Multi-zone technology discriminates between miniature handguns and harmless objects like keys and coins Multi-zone DFMD’s deploy ‘Continuous Wave Multiple Sensor Measurement Technique’ over the commonly used ‘Pulse Induction method’. This increases screening efficiency and cuts operating costs. Multiple zones of detection allow the exact location of concealed weapons to be pinpointed. A display shows if a weapon is located on the left, right or centre of the person being screened and if it is at ankle, knee, waist, chest or head height. If more than one weapon is being carried each is detected and its location shown. During an ensuing manual search, security personnel can immediately target the object, or objects, that created the alarm(s.).An important feature of horizontal multiple zone technology is its ability to efficiently discriminate between miniature handguns and harmless objects. People being screened can pass through the detector without the inconvenience of having to empty their pockets of normal amounts of keys and coins. Weapons manufactured from steel, various grades of stainless steel, aluminium, zinc alloys and mixed alloys are detected using a single operating mode.The technology offers excellent electrical interference rejection, thus eradicating false alarms that halt traffic flows. The equipment is also continuously active, which means that weapons or contraband cannot be passed, slid or tossed through the detector undetected.
In Multi Zone Detector there are different zones, they are
•Double Zone DFMD
In Double zone DFMD, it detects by dividing the body into two parts and recognises at which side the target is located.
•4 Zone DFMD
In 4 zone DFMD, it detects by dividing the body into Four parts and recognises at which Part the target is located.
•6 Zone DFMD
In 6 zone DFMD, it detects by dividing the body into Six parts and recognises exactly at which Part the target is located.
•8 Zone DEMD
In 8 zone DFMD, it detects by dividing the body into Eight parts and recognises exactly at which part the target is located.
•10 Zone Multi DFMD
In 10 zone DFMD, it detects by dividing the body into ten parts and recognises exactly where the target is located.
5.4.Why We Use DFMD?
We use DFMD’S to detect the Metal Devices and used for security purpose. These helps to avoid Bomb Blast’s, Murders etc., This also intimate the people that it is a place where there is a full security.
5.5. Where are they used? These DFMD’S are mostly used where is a need of more security such as Shopping Malls, Theatres, Temples, Universities, Govt areas such as parliament, party offices etc.,
5.6. How are they Fixed? Firstly the Left & Right Walls of DFMD has a Panel which needs to be connected to the Upper mother board which is presented at the top of DFMD. Now the Connections of alarm need to be fixed at the top. Now coming to the Sensor setting the connections of Yellow, Blue & Black wires need to be fixed correctly, after the sensor setting the last thing is to fix the walls of the DFMD with screws. After completion of fixing we need to check all the connections properly that they are in right position and working properly.
