The smartphone for securing hazardous lone work
The LifeTel 4L-EX1 is not only an extremely rugged but also a certified explosion-proof industrial smartphone for worldwide protection of your employees in Ex-protected zones (Android operating system). It was specially developed to secure lone work in Ex-protected areas.
Acceleration and position sensors trigger a dead man's alarm on this ATEX smartphone depending on the preconfigured settings. The wearer of the LifeTel 4L-EX1 then has the option to acknowledge the alarm. Using the built-in sensors, the specially designed emergency app detects the movement profile of the lone worker, so that in the event of an accident or a deliberate call for help by the wearer, the LifeTel 4L-EX1 automatically sends an emergency signal to the connected control center. A hands-free connection can also be established to communicate with the injured person. The integrated GPS tracking module transmits the position directly if needed. This immediately activates the rescue chain, so the injured person can be found right away with all the information transmitted by the LifeTel 4L-EX1 when every second counts.

Involuntary alarm
SOS emergency button / panic button
The red SOS button on the LifeTel 4L-EX1 is used by the user to trigger an immediate alarm. After a simple press, the LifeTel immediately sends alarms to three preprogrammed numbers. The alarms are sent as SMS and/or calls.
Voluntary alarm
Inactivity alarm / dead man's switch
The inactivity alarm monitors whether the user is moving with the LifeTel 4L-EX1. If no movement is detected after a user-defined period because the person is incapacitated, the device triggers a pre-alarm. This is indicated visually and acoustically. If the person does not move again within the duration of the pre-alarm, the LifeTel 4L-EX1 triggers the alarm and notifies the preset phone numbers via SMS and/or call.
Position alarm
The LifeTel 4L-EX1 monitors the device’s position using a position sensor. If the wearer of the LifeTel 4L-EX1 deviates from the preset position by more than 45 degrees for a defined period, the LifeTel 4L-EX1 triggers a pre-alarm. If the person does not return to the set angle range within the pre-alarm duration (e.g., due to unconsciousness), the LifeTel 4L-EX1 triggers the alarm and notifies the preset phone numbers via SMS and/or call.
Time alarm
With the time alarm, the LifeTel 4L-EX1 signals at defined times or intervals visually by blinking the large buttons and with an acoustic signal. By pressing any button, the user confirms that everything is okay. If no confirmation is received, the LifeTel 4L-EX1 triggers the alarm and notifies the preset phone numbers via SMS and/or call.
Escape alarm
With this alarm, the LifeTel 4L-EX1 reacts to frantic movements, such as those occurring during an escape. After the pre-alarm, the LifeTel 4L-EX1 triggers the alarm and notifies the preset phone numbers via SMS and/or call.
Fall alarm
Alternative to escape alarm – if an escape alarm is not expected during work but the risk of falls is significantly high, the alarm in case of a fall serves as an alternative.
24-hour service / emergency call center
Set who is notified when and with what information. You can manage the emergency call yourself or use the 24-hour service of one of our certified cooperation partners.
Recommended by professional associations and the DGUV.
W-LAN
If your GSM reception is too weak and you cannot make an emergency call, the LifeTel 4L-EX1 automatically switches to the W-LAN network.
