FC4 Lone Worker Protection DECT Handset

The robust industrial handset for lone worker protection

The FC4 LWP is a device thought and designed for Lone Worker Protection (LWP). Like other handsets of the FC4 series, an SOS button can be configured in order to send an alarm. The Man-Down function enables the device to further assure the protection of the employee carrying the phone. The in-built motion sensors monitor the movements and orientation of the device which can trigger an alarm if the configured parameters are met:

Step 1: a pre-alarm is launched and can be stopped by the Lone Worker if triggered by mistake

Step 2: if the pre-alarm is not stopped after a set amount of time, the alarm is sent

Alarms sent by the FC4 Lone Worker Protection can work in any GAP environments by sending a SIP call to a defined number. The IPBX installed then forwards the call appropriately. The alarm can also be sent to a specific systems connected to Funktel's DECT Controller.

In case of man down, the robustness and the screwed battery of this IP65 certified device assure that the alarm will be sent and taken care of.
