Operation
WARNING
1. Worker alerts generated by the connected system should not to be used in place of existing
safety program policies, practices and procedures. They are designed to be supplemental to an
established safety program. To reduce the risks associated with exposure to workplace hazards
which, if not avoided, could result in serious injury or death, users should follow all Safety
Supervisor direction on how to respond to alerts that may be experienced. The user’s situational
awareness should remain as one of the primary safety aspects in determining if there is a
condition that requires attention or to immediately leave an exposure area. Always follow
integrated TR-600 alarms when present.
2. To reduce the risks associated with hazardous voltage and fire which, if not avoided, could result
in serious injury or death:
a. Always inspect the Safety Hub and Safety Hub Docking Station for damage before each use.
b. Immediately discontinue use and contact 3M if there is a deformity of the enclosure or if the
Safety Hub does not easily seat in the Docking Station.
c. Only charge Safety Hubs using the provided Safety Hub Docking Station and power supply.
Connecting Your System
Your 3M™ Connected Safety Hub uses Bluetooth Low Energy (BLE) to connect and communicate with
system components in the connected PPE network. The devices a Safety Hub can pair with are the 3M™
Versaflo™ Connected Powered Air Purifying Respirator (PAPR) and 3M™ Connected Sensor. Devices in a
BLE network will take on a role as either a “central” or “peripheral” device. Peripheral devices in the
network have data that are transmitted to the central device, which is then responsible for processing
and using these data. The Safety Hub assumes a central role in this local BLE network, and other 3M™
Connected Equipment assume the peripheral role.
When a hub is removed from its Docking Station before going into use, it will initiate the pairing process
with nearby connected system components it is associated with if they are powered on. As the pairing
process begins, an alternating pattern of green and red LED’s flashing on the Safety Hub will be observed
until the devices have been paired with one another. Both devices will attempt to pair with an undocked
hub they are associated with upon start-up. If the Connected Sensor module is already installed in an
M-Series helmet, the pairing process will automatically begin with the appropriate hub when removed
from its dock. As a hub is put back into its dock at the end of use, all BLE links between those system
components will be disconnected.
