What is Siemens DO1152A Smoke Detector 90-5020-01540
The Siemens DO1152A Smoke Detector 90‑5020‑01540 is an optical smoke detector head of high quality, which belongs to the DO115xA series. These smoke detectors are widely used in marine, industrial, and commercial fire-safety systems for early detection of smoke from flaming or smoldering fires.
The device, manufactured in Switzerland, is compact, weighing ~170 grams, and corresponds to EN54-7 and EN54-17 standards, thus being compliant with widely recognized fire-safety regulations.
Key Features
Early Smoke Detection (Flaming & Smoldering Fires): The DO1152A is designed to detect the smoke-forming flaming fires and smoldering fires in their early stages, thus providing an early warning to avoid hazards.
Optimised Sensitivity & Low False Alarms: Advanced algorithms in the detector processor dynamically evaluate smoke signals, optimising sensitivity while reducing false alarms caused by dust, temperature fluctuation, or interference.
Consistent Performance Over Life Span: The detector compensates measured values over time, maintaining a practically uniform sensitivity throughout its operational life — ensuring reliability even after long usage.
Built-in Alarm Indicator: On-site alarm indicator provides clear visual notification in case of smoke detection useful for either maintenance or immediate local alert.
Easy and Versatile Installation: Designed to fit standard detector base, such as DB1151A, with accessory support for varied mounting needs-suitable for diverse environments ranging from cabins to machinery spaces, control rooms, or commercial buildings.
Marine-Ready & Industrial Grade: Constructed with durable materials and engineered for demanding marine and industrial conditions where stable performance under vibration, humidity, or variable temperature is important.
Applications
Due to its design and robustness, DO1152A is suitable for a wide variety of applications:
Marine Vessels & Ships: Installation in accommodation areas, engine rooms, cargo holds, decks — ensuring early fire detection and safety of the crew.
Offshore Platforms & Shipyards: Ideal for harsh industrial maritime environments where fire safety compliance and durability are paramount.
Industrial Plants & Factories: Workshops, warehouses, electrical rooms — anywhere there’s a danger of smoke or fire from equipment, wiring, or chemicals.
Commercial Buildings & Facilities: Offices, storage areas, machine rooms, server rooms — providing dependable smoke detection to safeguard human life and assets.
Mixed Automation/Marine Installations: As part of an integrated fire safety system on vessels or industrial plants, where early smoke detection can avoid damage or downtime.
Why Choose Siemens DO1152A?
Trusted brand and certification: Siemens’ brand reputation and compliance with fire-safety standards of EN54 assured quality and regulatory adherence.
High Reliability & Longevity: The balanced sensitivity and the built-in compensation maintain the effectiveness of the detector over years, minimizing the costs of maintenance and replacement.
Low False Alarm Rate: Smart detection algorithms that reduce nuisance alarms are indeed important for marine/industrial applications where dust, humidity, or vibrations are common.
Versatile Integration: It offers ease of mounting and integration with any fire alarm control panel. Application flexibility in retrofitting or new installations.
Cost-Effective for Safety: Given the possible cost of fire damage on ships or industrial plants, investment in a high-quality detector like DO1152A offers great ROI in safety and compliance.
