Phos 4.0 represents the most advanced version of Olympia Electronics' wireless emergency lighting control system.

Phos 4.0 enables centralized management of a large number of emergency lighting fixtures, from small to very large distances. The system consists of a central hub, which can either be an autonomous tablet or connected to a personal computer, to which the emergency lightings are wirelessly connected. Each emergency lighting has a built-in wireless transmitter-receiver, which communicates with the central hub and neighboring emergency lightings. The central hub receives information from all emergency lightings connected wirelessly to the system, providing an immediate overview of each light's status, such as battery status, illumination, any dimming function activation, while also collecting all information for daily, weekly, or monthly reports.

The system meets the requirements of the EN 62034 standard for automatic emergency lighting control systems and operates based on mesh network topology. Mesh topology is the safest way of communication and control of wireless devices, as its principle relies on the existence of multiple transmission channels between the devices-nodes of the wireless network. The presence of multiple communication channels between neighboring devices allows for the easy addition of additional wireless emergency lightings without disrupting the overall network operation, while the potential loss of a number of devices does not lead to network collapse.

Olympia Electronics places particular emphasis on the cyber-security of its products, providing WPA2-PSK network security, with advanced AES (Advanced Encryption Standard) wireless encryption. The AES algorithm is a symmetric block cipher encryption algorithm, based on a substitution-permutation network of data blocks of 128 bits with variable key length. The AES algorithm is used by the US government, providing the most guaranteed security of communications against brute force attacks.

The Phos 4.0 system is characterized by two basic principles: speed and safety. The advanced encryption of communications as well as the use of mesh topology during its operation ensure that the surveillance network of the emergency lighting system will continue to operate under the most challenging conditions. The presence of multiple communication channels allows for smooth use of the system in building installations, which otherwise would not allow the use of a wireless monitoring system, such as thick walls or the presence of metallic structures, while dramatically increasing the overall speed of the network.
