The technology’s filter recognizes such occurrences as a probable sensor drop or throw.
No, the sensors are specifically assigned to a unique, individual worker.
The sensor should be returned to the respective GC once work is fully completed on that site and a worker will not be returning.
Sensors are generally assigned at the site safety orientation conducted by the GC.
The spot-r system identifies if a worker slips, trips or falls on an active worksite and sends real-time notifications to a Safety Superintendent on-site. It also identifies and notifies if a worker is unresponsive or immobilized. The sensor’s self-alert button allows workers to report a hazard/unsafe work condition or potential safety incident. The audible alert feature allows for site-wide notification in case of emergency or evacuation.
The sensor is designed to be clipped onto a worker’s waist belt to register any safety incidents on-site. It should not be worn on a safety vest or helmet as a substitute.
The sensor automatically turns on when a worker approaches the active spot-r job site and goes into sleep mode when a worker leaves the range of the job site’s spot-r network, which typically extends a few hundred feet beyond the site perimeter.
The sensor only records and transmits information within an active spot-r job site network. The sensor enters sleep mode when it leaves the range of the job site’s spot-r network.
No, the system communicates with a closed, localized network, which is deployed specifically per each site’s layout.
The system automatically logs information already collected by pencil & paper on-site, including when a worker enters and leaves a worksite and their general location within worksite zones. It also collects information related to a slip, trip or fall safety incident, including time and general zone location of the incident.
A job site’s Safety Supervisor will have access to the information dashboard, along with any other personnel authorized by the appropriate general contractor to view the information.


The iPhone Personal Hotspot feature uses the iPhone’s name as the hotspot network name. By default, this generally contains a special character for the apostrophe (’). Special characters in network names are not supported by the SKYi. To work around this, change the name of you iPhone to remove the special character. It can be replaces with a standard apostrophe (‘) or removed altogether. Personal Hotspot must then be turned off and on again to change the name of the network. To change the name of Go into Settings->General->About. Select Name, edit the name, and press Done.
No, your sensor will communicate solely with the device to which it is paired.
Yes, the SIM-P is fully sweat-proof and waterproof. We have several teams using the device for water polo. Please note, you can only safely wash your headband or skullcap with the SIM removed; it will not withstand the washing machine and dryer.
You will want to insert your SIM-P into the Triax approved headbands. Each headband has a pocket in the back. The pocket with the sensor in it should be located at the back of the head. (See pictures on our website for proper wear). The green on the Triax logo should point to the ground, and the blue toward the sky.

Solid Green – Battery charge is OK, ready to use.

Solid Yellow/Amber – Battery charge is low, charge soon.

Solid Red
 – Battery charge is very low, charge now.

3 Red Flashes – Battery is extremely low. SIM has entered battery protection mode. Charge immediately.

The SIM-P battery lasts for 8-10 hours depending on impacts sustained.
SIM-P can be charged using a USB connection or wall power outlet. Plug the SIM-P device into the USB dock that comes with your device. You can plug the SIM-P into any USB portal or connect it to the wall charger that comes with your device, and plugs it into a power outlet. The charging contacts must face downwards into the dock. There is an LED light on the top left corner of your SIM-P. When the light flashes green, it is 100% charged. When the light flashes yellow, the battery is charging properly. When the light flashes red, the battery is not charging. If the light flashes red please contact the Triax support team. It is safe to leave the SIM-P in its charging dock indefinitely. This will not overcharge or harm the internal battery.
You may download our app on the Apple App Store and / or by clicking here using your iOS device. SIM-P is compatible with iOS 7.0 or later and Bluetooth 4.0. Triax offers Bluetooth 4.0 syncing to select iOS devices. Syncing is available on all iOS devices after the iPhone 4S. Please check back to see the latest compatible devices with sync support.
To turn on the SIM-P, press the power button on the lower right corner. A green LED light will flash in the top left corner. To turn off the SIM-P, hold the power button. The LED light in the top left corner will flash a yellow light. Then, a red light will flash once, and the device will turn off.
Prior to its first use, the SIM-P should be charged for a minimum of 4 hours (using only the Triax-supplied charging dock). You will also need to pair your SIM-P with your mobile device. This only needs to be done once, and when you open the Triax app it will walk you through the steps. To pair your device, first make sure Bluetooth is turned on.


If the device won’t turn on try charging it for at least one hour. If the device still will not turn on, contact Triax customer service at
There is no reset button for the SIM-P. If you have any issues with the device, place the SIM-P in the charger, and charge it fully. When the device is fully charged, it will reset.
When your paired device has Bluetooth turned on and is within 35 feet of the SIM-P, it will sync automatically with your Triax app.
An NIT is a term Triax created to describe “false impact” events. We use a proprietary algorithm to filter out “false impact” events that may occur when dropping or tapping the sensor. When your NIT filter is not activated you will see more activity from your sensor which can show impacts that did not actually occur. We recommend you leave your NIT filter on at all times.
The SIM-P can store 170 events locally, and will erase once they are synced with the Triax app. If you exceed the 170 events stored locally, the oldest event recorded will be overwritten.
No. The Triax SIM uses a 900 MHZ radio frequency which is one of the CDMA cell phone bands that is widely used today. The transmitter on the sensor is “OFF” unless sending data received from an impact or doing a routine check-in with the base station. An easy way to visualize this is to a compare the SIM to a smartphone. The SIM emits about 3% the total amount of what your child’s smartphone emits. So if you are ok with your child using a smartphone, the Triax SIM should be too! A more technical description below: A class 2 Bluetooth device (typical headset) is about 2.5mW peak. SIM-G is higher (perhaps 20mW peak, and less than .2mW average), but still much lower than cell phone (>500mW).
