Which Troubleshooting Tips Should You Keep in Mind?

The auto sliding doors play an important role in ensuring there is convenience in getting in and out of a building. As such, they are vital to your business. What if the door is not working right? In such a case, there is a need for proper investigation into the problems.


The door alarm keeps chiming

If the door keeps chiming its alarm, you may want to consider pressing the reset button. This will reset it to the default settings where it will help mute chiming. However, you need to understand why the alarm is chiming in the first place. So do not just ignore it forever.


The door has no power

There are times when it is not possible to open or close the door because there is no power. The first thing you should check if the power is turned on. Sometimes a breaker might flip and you end up with a door having no power. Head over to the breakers and turn on the breaker for that specific clean room door.

If that was not the issue, there could be other electrical problems. As such, it may be time to call an electrician or a professional who deals in the maintenance of such doors to help pinpoint any other electrical issue.


The door has rough movements

The auto electrical sliding door is supposed to slide smoothly on its rail with minimal noise. If you find that the door has rough movements, it might be a combination of several things. First, disconnect power to the door to do more investigations. Try to open the doors manually. If the doors have too much resistance, check the door tracks to see if there is any debris that might be preventing it from working properly.

You should also examine weather stripping. There are times when debris, grease, or rock salt can easily get lodged into the door mechanism. This would prevent it from moving smoothly. Use a good degreaser to clean the excess grease from the tracks. You can now apply new grease and check to see if that solves your problem.

You also have to consider checking the level of the door frame on the floor. Sometimes the floors can warp over time thus causing an imbalance in the door frame. When the door frame is no longer on level, the door starts to have rough movements. In such a case, you need professional help to handle these rough movements.

There can be many other problems you may experience with an auto sliding door. What is important is that you always get professional help to handle these problems.

Which Sensors are Used in an Auto Sliding Door?

Auto sliding doors work mostly based on sensors. These sensors are what will trigger the opening and closing of the door. There are various types of sensors available each working based on a different principle. Here are the common options as sensors for auto sliding doors.


Radar sensors

These sensors are designed to detect people in a specific location. As such, so long as you are walking around the detection area, the doors will open so that you can get in or out of the building. These sensors are also liked as they can detect even plastic, wood, metal, and more. this makes them highly versatile for various applications. The sensitivity is also adjustable to suit your needs.


Pressure sensors

These sensors are placed under a mat next to the door. The sensor works by detecting the weight on the mat before opening the door. The door will only open if the weight is more than the default value. The door will remain open so long as there is additional weight on the door sensor mat. As such, the door cannot close in on a person who is still within the doorway. This generally improves safety.

Motion detectors

This is probably the most common type of sensor for auto sliding doors. The sensors can be installed on the side of the doors so that they can detect motion before opening. You have to drive the traffic to the door to be perpendicular to the door. This will make it easier for the sensors to detect those approaching the door.

Keep in mind that these sensors only detect motion. So, if a person is just standing, the door will not open until there is movement.


Infrared movement sensors (passive)

These sensors work differently from active infrared sensors. They are designed to store the images it detects for a given range. As such, it will be using this information to create a precise detection range. This makes such sensors highly accurate. As such, they can be used for auto sliding doors and even garage sliding doors too.


Active infrared sensors

These sensors are equipped with receivers and transmitters. The receiver will contain high-performance optics that enables it to recognize whether there is infrared light from the transmitter or not. This is to ensure that there is enough protection for those going through the auto sliding doors or even the revolving doors too.

Do not worry about the door crashing into you while passing through the doorway. You will be happy to know that the sensors are always designed with safety in mind. Also, proper maintenance can help avoid experiencing such inconveniences.


Are the Auto Sliding Doors ADA Compliant?

Figure 3 Auto Sliding Doors for Hospitals

Most, if not all auto sliding doors are most likely to be ADA-compliant. This means that the doors are designed to allow ease of entry into a building even for the disabled. Let us say someone has a wheelchair, he or she should be able to get through the doorway with ease and not worry about barriers being removed first before the wheelchair can pass through. That is not the only reason, even those with other disabilities should be able to use the door with ease.

The auto sliding doors have to meet certain requirements to make them easily accessible. Below are the locations that should have ADA-compliant doors.

  • Each of the entrance in the newly built facilities should be accessible to people who use wheelchairs or have other mobility impairment issues
  • Tenant spaces in malls or other buildings having multiple businesses. This should ensure that the disabled can also easily access the businesses.
  • Any accessible rooms or spaces in different buildings. The disabled in a wheelchair or any other mobility impairment should be able to access such spaces
  • Public entrances serving people in transit should also have ADA-compliant doors.
