We know there’s nothing worse than when you go through airport security screening, and set off the walk-through metal detector, not once, twice, but three times and then have your hand luggage searched for a pair of scissors. 

Here are some tips to help you proceed through screening with as little fuss as possible.

The walk through metal detector

1. Remove your shoes. Unless you are wearing rubber thongs, your shoes are likely to have metal in them—most shoes have metal under the arch that support your foot, and these can sometime have enough metal in them to set off the metal detector.
2. Remove heavy watches and/or jewellery. Heavy watches and jewellery often set off the walk-through metal detector.  We suggest you secure your jewellery in your carry-on bag or in our dedicated jewellery container to be x-rayed.
3. Remove your belt. Some belts have heavy belt buckles or are studded.  Either of these is likely to set off the walk-through metal detector.  It can be easier just to take off your belt before you walk through.
4. Empty your pockets.  Lose change, mobile phone and keys are all culprits for setting off the walk through metal detector.  Save yourself time, check and empty your pockets before you walk through the metal detector.
5. Advise the security staff if you have a pace maker or have had a joint replacement.  If you have a pace maker, you should not proceed through the walk through metal detector, but instead, be ushered through and be manually patted down.  If you have had a joint replacement, you will be asked to proceed through the walk through metal detector, which will alarm, you will then be manually patted down.

If at any time when passing through the walk through metal detector the alarm does sound, the guard will simply ask you to remove any metal objects and place them on the trays provided.  You will then be asked to walk through the metal detector a second time.

The x-raying of hand luggage

1. Remove any aerosol cans from your carry-on luggage.  This enables the security guards to quickly check that the can has a lid or a lock to stop it from accidently spraying during the flight.
2. Remove any notebook computers from your carry-on luggage.  This provides the guards a clear view of your computer as it is x-rayed. 

Bonus tip

1. Check your bags for any forgotten items that may be classified as ‘prohibited’, and remove them prior to entering screening.  This will save you time while you and the guard search your bag for the item and will save the item from being disposed of.

By following these simple tips as you enter the screening area, your chances of experiencing a smooth security process is very high.

An automatic sliding door system is popular in the market today. This is commonly experienced and seen in operation on most public buildings, commercial, retail, medical leisure, and office. From the point of view of users, automatic sliding door system is easy, convenient, and fast to use. As a door system, this provides an efficient, effective and safe way of controlling access inside the building. In other cases, it also brings aesthetic appeal in the building. 

In most situation wherein many people are seen leaving and entering a building, perhaps pushing or carrying things in the supermarket, automatic sliding door system provides a big opening for a safe and quick touching or opening of any part inside the door. It also provides a greater flow that leads to less confusion among people because they are able to look at each other on both sides of the door. The door slide and the big spaces created allow people to leave and enter on the same opening. 

Apart from it, the easy action of closing and opening of the system can help in retaining heat inside the building. In effect, there are more energy bills that are saved and even a comfortable and convenient environment is maintained. 

More so, there is also a sliding door system with tight seals that prevent drafts. Even the airflow from and to the building is effectively controlled and regulated through the use of this system.

There is also an automatic sliding door system with door panels that are constructed of strong glass. As a result, the lights are allowed to come inside the building. Other than sensors that prevent trapping, other door system has a device that allows for an emergency opening, as the main power does not succeed. On such normal power circumstances, the system allows the doors to slid back which provides clear and large spaces and evacuates people during emergency.

For a building that has its own architectural shape and design, there is an automatic sliding door system that provides all benefits in such a tailored way. Since look and image of buildings is important, automatic sliding door system can be found that slides in such a circular motion.  The curve of the glass section gives a prestigious and sophisticated look inside the building.

Like it or not, as a business owner you are responsible for remaining compliant with the Americans with Disabilities Act. The law, in a nutshell, requires compliance to make your facilities accessible to the disabled, but it isn’t until someone sues you citing the ADA that things get really expensive. The best tactic is to try to avoid these lawsuits before they happen. The good news: As a small business owner you may also qualify for tax credits by making the necessary changes.

ADA compliance issues can get confusing (consult an attorney if you have any questions), but here are a few basic tips to help keep you out of the courtroom. You may not be able to take all of these steps without spending a fortune, but the more you can get done, the less likely you are to face a lawsuit.

1) Have your business checked by an ADA qualified inspector. They can provide you with a report that lists any known issues.

2) Barriers that block access for disabled persons to pass through should be removed. Check entrances to make sure accessible equipment is in working order, including elevators, automatic door openers, and wheelchair lifts.

3) Offer to come to customers who are physically unable to come to your location. Conveniently place these notices where they are visible to the public. This will show that you are making an effort to meet the needs of your customers even if your building isn’t up to code.

4) Ensure handicapped parking is clearly marked and close to the facilities. Ensure the spaces are large enough so wheelchairs can maneuver around easily.

5) Washrooms must allow for handicapped access; designate washrooms or stalls for the handicapped equipped with grab bars.

6) Have soap dispensers and paper towel dispensers placed at a height of 48 inches off the floor. This is actually convenient for everyone (including children), not just disabled customers. All bathroom equipment should require minimal effort to operate: specifically, less than five pounds of force.

7) Automatic Entrance doors are required to be at least 36 inches wide and have 32 inches of space when open, the standard for most modern doors. Doors that don’t meet this requirement may have to be replaced. (Updated.)

8) If you have a sales or service counter check that it is no higher than 36 inches tall. If this isn’t feasible, designate an area where handicapped shoppers can receive assistance.

Components

• Sliding gates include a range of metal and wood components. These include the fixed fence, sliding fence, trolley, fixed post, springs, hinge, motor and switch (if automatic) and screw drive track.
• Homemade sliding gate plans typically include a scaled diagram of the gate's components and how they fit together. These include measurements of metal fence segments and wood segments, as well as the angles at which the parts must be connected together. Step-by-step instruction topics include the latch design, preparing the grade for the track, installing the track and determining the gate height, making the gate and end stop, installing the gate, and fitting the latch and guide rollers.

Take off the screen door if you have one. Grab both frame sides in the middle, and lift the door up. Pull the bottom away from the track while holding pressure upward. Use a slotted screwdriver to pry the bottom wheels off the track if the door does not freely come off.

Take off the automatic door on the outside first. In most cases, that will be the stationary door, which must be freed from its fixed position. Remove the lower track cap running from the edge of the fixed door to the door jamb. Stick the blade of a slotted screwdriver under the cap, and pry it upward. Remove the holding screws from the stationary door frame with a Phillips head screwdriver. They will be holding the frame to the outer door jamb at the upper and lower corners, and possibly midway from top to bottom.

Slide the door out of the jamb if possible. Use a pry bar to free it if needed. Roll the door to the center of the track. Have a helper grab one side of the frame while you take the other and push up on the frame to swing the bottom of the door away from the lower track. Use a Phillips screwdriver to lower the wheel setting if the bottom wheels do not come off the track. Stick the screwdriver through the holes in the lower door to reach the adjustment screws. Turn counterclockwise to recoil the wheels.

Remove the automatic sliding glass door. Roll it to the center of the track. Grab one side, with your helper holding the other, and push upward to swing the bottom toward the outside as you did for the stationary door.

passive infrared 

The passive infrared (PIR) motion detector is one of the most common sensors found in household and small business environments. it works entirely by detecting the heat energy given off by other objects. it works entirely by detecting the heat energy given off by other objects.

Microwave sensor detectors

This device emits microwaves from a transmitter and detects any reflected microwaves or reduction in beam intensity using a receiver. To reduce false alarms this type of detector is usually combined with a passive infrared detector.It is usually installed with an automatic sliding door.

Photo-electric beams

Photoelectric beam systems detect the presence of an intruder by transmitting visible or infrared light beams across an area, where these beams may be obstructed. To improve the detection surface area, the beams are often employed in stacks of two or more.

Smoke, heat, and carbon monoxide detectors

Most systems may also be equipped with smoke, heat, and/or carbon monoxide detectors. Smoke detectors and heat detectors protect from the risk of fire and carbon monoxide detectors protect from the risk of carbon monoxide.

Passive magnetic field detection

This buried security system is based on the Magnetic Anomaly Detection principle of operation. The system uses an electromagnetic field generator powered by two wires running in parallel.  Both wires run along the perimeter and are usually installed about 5"/12cm apart on top of a wall or about 12"/30cm below ground. Thewires are connected to a signal processor which analyzes any change in the magnetic field.
