Frequently Asked Questions

Find answers to some of the common questions about
Impact-Alert Sport-Tuned™ Sensors

1. IS THIS A CONCUSSION DEVICE?
No. It is a helmet safety device.
The sensor measures long-duration impacts and links these events to possible symptoms that can occur days later.

2. HOW DOES IT WORK?
The Impact-Alert sensor is applied to the top or rear of a helmet. The device has two sensing tubes, one set for a medium long-duration impact and one set for a high long-duration impact. The tubes turn red when the threshold for each tube has been exceeded.

3. WHY DO WE NEED THE DEVICE?
Today, helmet shells are designed to take multiple impacts but the inside liners are not. If you read the helmet manufacturers' instructions when purchasing a helmet, it states that the helmet is designed to withstand one significant impact before the inner liner is compromised. The Impact-Alert device will tell you when you have received a long-duration impact and when your helmet has been damaged and should be replaced.

4. HOW IS IT INSTALLED?
The sensor is installed on the helmet along the centerline from either the top or the rear. Use alcohol or other cleaner to remove any grease or oil from the surface. Peel the paper backing off the sensor and place the sensor body on the helmet with the red arrow facing upward. Press the sensor body onto the helmet, then press the decal onto the helmet working from the center out. HOW TO USE.

5. WILL THE DEVICE HELP IN CONCUSSION MANAGEMENT
Yes. Before a participant can be monitored for symptoms, an event has to occur. Long-duration impacts at any G level can possibly cause concussions. The problem is that there is no concrete method of knowing when the event has taken place. Concussion symptoms can take hours to days to appear and without knowing an event has occurred you might misinterpret the symptoms for something else. 

6. HOW RELIABLE IS THE DEVICE
The device is not battery operated so it won’t run out of power when its needed. The device is very reliable and will work in all weather and temperature conditions.

7. HAS THE DEVICE APPROVED OR BEEN TESTED?
Impact-Alert's hockey helmet impact indicator is a CSA (Canadian Standards Association) certified component. It has also undergone independent third party testing.

8. WHAT HAPPENS WHEN THE DEVICE TURNS RED?
This means the user/helmet has taken a long-duration impact. If both sensors have turned red during use, the helmet should be replaced and the user should be monitored for symptoms of a concussion. If only one sensor has turned red during use, the helmet should be checked for cracks or deformations.

9. CAN THE DEVICE BE TRANSFERED?
No the device is only good for the helmet it was originally installed.

10. WHAT IS THE WARRANTY?
Impact-Alert hereby warrants our Impact-Alert Sport-Tuned™ sensors to be free from defects in materials and workmanship, under normal use for a period of one year from the date of purchase. The sensor will operate indefinitely as long as the helmet is in good working order.

11. WHAT HAPPENS IF THE USER DROPS THE HELMET?
The sensor will take some abuse as most impacts like a drop or throwing it in the bag are short duration impacts. If the user throws it down with force on a hard surface there is a good chance the sensor with activate (turn red) and the helmet could be damaged as a result. Some helmets with rigid foam liners (ex. cycling, alpine, etc.) can be damaged when dropped onto a hard surface regardless if the helmet is in use or not. 

12. IF FOOTBALL HELMETS ARE MEANT TO TAKE MULTIPLE IMPACTS, HOW DOES IT WORK?
Currently, the only legislation in place regarding football helmets is that a helmet has to be replaced after 10 years of use.  Football helmets are reconditioned on average every two years. The liner is sanitized and the outside shell is checked for cracks. The reconditioning of helmets is arbitrary and varies with every school or association. It has no bearing on how many significant impacts the helmet has taken.
The Impact-Alert helmet sensor alerts the coaching staff that the helmet has taken a significant long-duration impact. They can keep a log of what helmets have taken these impacts and then know which helmets need to get reconditioned.
