Fire alarm systems

Siemens Cerberus PRO – fire alarm control panels

Siemens Cerberus Pro is a family of fire alarm control panels designed for facilities where not only detection matters, but also scalability, networking and the ability to manage more advanced system logic. The FC722 addresses the needs of small and medium-sized installations, the FC724 covers larger systems, and the FC726 supports the architecture of large and very large facilities.

Panel family FC722 / FC724 / FC726

Networking up to 64 stations

Max. capacity up to 1512 addresses

A family of panels for different scales of fire alarm installations

The Cerberus PRO system can operate in smaller facilities, larger installations and extensive network architectures, where room for future expansion and integration is essential.

Siemens Cerberus Pro – what this system means in practice

In practice, Cerberus Pro is not just a control panel collecting signals from detectors. It is a system in which the panel supervises detection loops, identifies alarms, faults and disablements, manages alarm logic and cooperates with field devices and operator terminals. This is especially important where the fire alarm system goes beyond simple detection and works together with smoke control, alarm transmission, fire scenarios and the building’s technical infrastructure.

What sets Cerberus Pro apart from simpler fire alarm approaches

Networking and system architecture

In systems of this class, the key factors are not only the loops, but also the ability to build one logical fire alarm architecture where a single panel is no longer the optimal solution.

Handling dependencies and controls

Cerberus PRO is suitable where the system must cooperate with smoke control, alarm transmission, operator terminals and more advanced fire scenario logic.

Siemens indicates the possibility of building networks of up to 64 stations including control panels and terminals, with system communication and network functions compliant with EN 54 requirements.

Cerberus Pro control panel family

FC722

A compact addressable control panel for facilities where full Cerberus Pro functionality is required, but without moving into a large modular architecture.

FC724

A control panel intended for larger fire alarm systems where the number of loops, zones, controls and interfaced devices increases.

up to 504 addresses
4 loops as standard, up to 8
12 programmable inputs/outputs
networking up to 64 stations

FC726

A modular control panel for extensive fire alarm systems where scalability, network architecture and reserve for future expansion are important.

Importance for designers and installers

Selection is not only about detector count

When selecting Cerberus Pro, it is necessary to consider the number of loops, the fire zone structure, required controls, external devices, the investor’s expansion expectations, and the need to network panels and terminals.

The importance of the fire scenario

In facilities where the fire alarm system works together with smoke control, access control, lifts, voice alarm systems or other executive systems, the panel should be selected based on the logic of the entire fire scenario rather than on a simple quantitative balance.

Practical conclusion

Siemens Cerberus PRO is a solution for facilities where the fire alarm system must be not only formally compliant, but also scalable, operationally predictable and ready to integrate with the broader building safety infrastructure.
