Siemens ASD+ aspirating smoke detectors provide ultra-early fire detection in critical infrastructure and demanding environments. With single- and dual-chamber options, they enable customized solutions for applications of any size and offer the market’s largest coverage area. Dual wavelength technology accurately distinguishes smoke from deceptive phenomena, reducing false alarms and detecting even electrolyte gas particles early on.
ASD+ uses advanced dual wavelength technology to detect fires at the earliest stage, including invisible particles like electrolyte gases. It reliably distinguishes smoke from dust or steam, reducing false alarms.
With a coverage range of up to 21,500 sq ft per unit, the ASD+ offers one of the largest ranges on the market. Its single- and dual-chamber options allow for flexible scaling of both small and large applications.
The ASD+ is designed for critical infrastructure and challenging environments where point detectors are ineffective. It provides precise and reliable fire detection for data centers, industrial sites, and logistics facilities.
The product range includes:
FDA462 | FDA461 | FDA442 | FDA422 | |
|---|---|---|---|---|
Area coverage | 21,500 sq ft | 15,000 sq ft | 10,000 sq ft | 5,000 sq ft |
Linear pipe length | max to 2 x 393 ft | max to 2 x 164 ft | max to 393 ft | max to 164 ft |
Branched | max to 1,968 ft | max to 820 ft | max to 984 ft | max to 410 ft |
The ASD+ Connect app enables fast and intuitive commissioning through a guided, highly automated setup process. It reduces installation time and effort while improving accuracy and usability for site and service teams.
The ASD+ features a modular design that allows for the easy replacement of key components without changing the entire unit. This extends the product's lifespan, lowers maintenance costs, and ensures continuous system operation.
ASD+ in data centers
In data centers, high airflows can hinder detection. ASD detectors are placed where air currents direct the smoke, enabling very early and reliable detection.
