Personal emergency signal systems, which are built and parameterized according to the product standard VDE V 0825-1, are suitable to be used for personal emergency signaling during dangerous solo work in accordance with DGUV regulation 112-139 (ex BGR / GUV-R 139).
Life Tel 4 L EX - smartphone for lone workers in ATEX areas 1/21 with emergency app
Outdoor smartphone incl. App for the protection of lone work
The mobile personal emergency signal device Life Tel 4 L Ex has been specially developed for securing lone workers who work at individual workstations on extensive facilities. The Life Tel 4 L Ex is a robust smartphone and, in combination with the lone worker protection app, is particularly suitable for outdoor use. You can manage the emergency call of the Life Tel 4 L Ex yourself, e.g. by the porter, own company security or your own control center. But you can also use an external 24-hour emergency call control center. This must be able to manage and process phone calls and SMS, as these sometimes transmit GPS coordinates. If necessary, you are welcome to use the 24 hour service of one of our cooperation partners. Please contact us for more information.
The Life Tel 4 L Ex sends out an alarm based on predefined settings when there is no movement. If the Life Tel 4 L Ex detects an irregularity, a pre-alarm occurs first. If this pre-alarm is not switched off by the user because the user may be unconscious, the alarm is forwarded to a self-defined number or to a control center. The respective contact person now tries to establish voice contact with the accident victim. If that is not possible because the person concerned is no longer able to do so, action must be taken.
If the lone worker is working in the open, the person's position can be transmitted via GPS tracking so that emergency doctors, fire brigade, etc. can be notified and can act. An action plan should be available so that if the worst comes to the worst, the casualty can be helped as quickly as possible.
The working person wears the Life-Tel 4 L Ex on the upper arm and in an emergency triggers an alarm via the lone worker protection app and notifies up to six telephone numbers via SMS and / or phone call. This also happens if the person is not able to do this himself (voluntary alarm). The working person triggers a manual (voluntary) alarm with just one push of a button.
Ex protection certified
As a personal emergency signal device, the Life Tel 4 L EX complies with the guidelines of DGUV 112-139 for working alone and also serves as an optimal solution for explosion-protected areas (ATEX / EX protection certificate).
The Life-Tel 4 L EX offers extensive alarm functions which can be combined as required.
Lone worker protection app
With the help of the self-developed emergency app of the Life-Tel 4 L EX, the person in need is found immediately and can thus be looked after as quickly as possible.

SOS emergency call button / panic button
The red SOS button on the Life-Tel 4 is used to trigger an alarm immediately by the user. With a simple push of a button, the Life-Tel immediately sends alarms to three preprogrammed numbers. The alarms are sent as SMS and / or phone calls.
No-movement alarm / dead man's switch
In the event of a no-movement alarm, the Life-Tel 4 monitors whether the user is moving. If it does not detect any movement after a self-defined period of time because the person is unable to act, the device triggers a pre-alarm. This is indicated optically and acoustically. If the person does not move again within the duration of the pre-alarm, the Life-Tel 4 triggers the alarm and notifies the preset phone numbers via SMS and / or phone call.
The Life-Tel 4 monitors the position of the device using a position sensor. If the person wearing the Life-Tel 4 deviates from the preset position by more than 45 degrees over a defined period of time, the Life-Tel 4 triggers a pre-alarm. If the person does not return to the set angle range within the duration of the pre-alarm (e.g. due to fainting), the Life-Tel 4 triggers the alarm and notifies the preset phone numbers via SMS and / or phone call.
In the event of a time alarm, the Life-Tel 4 reports optically at defined times or time intervals by flashing the large buttons and an acoustic signal. By pressing any button, the user acknowledges that everything is OK. If there is no confirmation, the Life-Tel 4 triggers the alarm and notifies the preset phone numbers via SMS and / or phone call.
With this alarm, the Life-Tel 4 reacts to hectic movements such as those occurring during an escape. After the pre-alarm, the Life-Tel 4 triggers the alarm and notifies the preset phone numbers by SMS and / or phone call.
Alternative to the escape alarm - if an escape alarm is not expected at work and the risk of falling is significantly high, the alarm in the event of a fall serves as an alternative.
