Lighting the Way to Safe Innovation:
LED and Power Solutions for Infrastructure.

Exista provides the right power supply for complete fire alarm systems and associated peripherals. The standards and certifications involved are particularly demanding, as they are significantly stricter than those required for many industrial applications. Through regular audits in the VdS fire protection sector, Exista has a detailed understanding of the processes, from development and testing through to series production and service. The result is robust, fail-safe power supplies and UPS solutions that function reliably even in the event of an incident.

Automated door and gate systems must operate quietly, quickly, and unobtrusively, while also being highly reliable. In confined installation spaces, space is often at a premium, while powerful motors generate high peak currents. Exista power supplies and power electronics are designed for these requirements—with high power density, dynamic performance, and optimized EMC. Power consumption is minimal in standby mode, while full power is available during operation for fast motion cycles.

Modern buildings are becoming increasingly connected and intelligent—from roller shutters and access control systems to lighting controls, ventilation, and surveillance solutions. All these systems rely on a compact, efficient, and reliable power supply. Exista offers solutions with single or multi-output, optionally combined with buffering or UPS functionality via Li-ion or lead-acid batteries. This ensures that building automation remains operational even during power outages, and critical functions continue to run in a controlled manner.

Even in seemingly simple applications such as urinal controls, the power supply is a critical factor. Condensing moisture, cleaning agents, and tight installation spaces place high demands on design and protection concepts. Exista develops application-specific power supplies tailored for longevity, water resistance, and maintenance concepts. Experience with encapsulation processes and design for household environments ensures that the solution continues to operate reliably even after many years—in a location that requires as unobtrusive a function as possible.

Video surveillance, access control, and alarm systems must be available around the clock. Power supplies for these applications must compensate for voltage fluctuations, provide backup power in the event of a failure, and often deliver multiple voltage levels. Exista combines power supplies and UPS functions to ensure a stable power supply for cameras, readers, control centers, and network components. Monitorable outputs and communication interfaces facilitate integration into higher-level monitoring systems.

Lighting and signaling systems in emergency exits, parking garages, or outdoor areas place special demands on reliability and environmental suitability. Exista power supplies are designed for continuous operation, temperature fluctuations, and mechanical stress, and can be equipped with buffering or UPS if required. This ensures that safety-critical lighting and signaling systems remain operational even during power outages or switchover procedures.

Depending on the application, different standards and guidelines must be observed. EN 62368-1 applies to many devices in building automation and communications technology, while household applications typically fall under EN 60335. In fire protection, VdS guidelines and, in some cases, standards such as EN 54-4 for power supplies to fire alarm systems also apply. Exista takes these requirements into account as early as the design phase to ensure that approvals can be obtained efficiently.

UPS systems in building automation must not only ensure sufficient backup time but also support defined shutdown or switchover strategies. Key considerations include battery sizing, the load profile of the consumers, the ambient temperature, and the required availability. In addition, there are requirements for communication interfaces to integrate status information—such as battery status or remaining runtime—into control systems. Exista tailors UPS solutions so that they integrate seamlessly into the respective infrastructure.

Monitorable power supplies enable real-time monitoring of parameters such as voltage, current, temperature, and battery status. This allows for proactive planning of maintenance, service calls, and spare parts (predictive maintenance). The risk of failure is reduced because critical trends can be detected early and corrective actions taken. This increases system availability and transparency, particularly in safety-critical applications such as fire protection, access control, or surveillance systems.
