Aspirating smoke detectors for data centers
In data centers, high airflows can hinder detection. ASD detectors are placed where air currents direct the smoke, enabling very early and and reliable detection.
Siemens aspirating smoke detectors (ASD) provide very early fire detection to protect critical infrastructure in demanding application areas. Dual wavelength technology helps businesses maintain continuity by avoiding false alarms and detecting electrolyte gas particles early.
Siemens ASDs offer the largest coverage area on the market, with a single unit monitoring an expansive space of up to 6,700 m². They come in a range of models to suit your needs:
All devices conform to EN 54-17 and EN 54-20 and have VdS approval. Several have SL2 cybersecurity certification.
Redefine the standards for early smoke detection with precision technology that distinguishes between smoke and deceptive materials to avoid false alarms and bring peace of mind to building and business owners.
Replace essential parts with a modular feature that enhances cost efficiency and sustains continuous system function — an essential layer of your fire safety — while reducing your environmental footprint.
Rely on our wide range of support options, from documents to tools and data — everything you need to plan your next fire strategy project with confidence.
Dual and single-chamber ASD+ are part of the ASD portfolio. Employ dual-chamber for larger and single-chamber ASDs for smaller applications. The maximum coverage of an ASD+ reaches up to 6,700 m2.
QR code commissioning and the innovative ASD+ Connect app facilitate an accessible, effortless online setup process. This highly automated and user-friendly approach markedly reduces time and effort.
Support installations with the highest sensitivity requirements. ASDs are built for the most demanding applications, including data centers, online retail distribution centers or industrial production facilities.

In data centers, high airflows can hinder detection. ASD detectors are placed where air currents direct the smoke, enabling very early and and reliable detection.

In warehouses, point detectors on high ceilings can be too slow to detect fire. ASD detectors, on the other hand, are placed close to the root of incipient fires, offering near-immediate detection.

ASD detectors are sufficiently sensitive to detect the venting (off-gassing) of electrolyte vapor particles, which allows for very early detection of lithium-ion battery fires.
