: The DSZ 3000 is often used in "double interlock" or "pre-action" setups. In these systems, water only discharges if two separate events occur—for example, both sprinklers in a unit must open or a fire detector must also be triggered—ensuring water isn't released due to accidental mechanical damage. Remote Monitoring : It transmits alarm signals and system status to a permanently manned location to ensure an immediate response in case of a real fire. System Integration
: A single pre-action unit contains two separate sprinkler elements arranged in a cast housing. Extinguishing water will only discharge if both separate elements are opened by heat.
The core protective mechanism of a pre-action system lies in its "double-interlock" or "double-action" feature. A single Minimax pre-action sprinkler unit consists of two separate sprinkler heads housed in one assembly. For extinguishing water to be released, of the glass bulbs in the assembly must burst. This redundancy significantly reduces the chance of a false release, which could result from accidental damage to a single sprinkler head.
The Minimax DSZ 3000 water treatment process involves several stages: Minimax Dsz 3000
: Available with front panels in English or German.
: Relays prioritized telemetry up to main Fire Alarm Control Panels (FACP) or industrial SCADA platforms via dry contacts or proprietary bus configurations.
: In high-risk environments, accidental water damage can be as costly as a fire. The DSZ 3000 ensures that water only enters the system piping after a confirmed fire signal, effectively converting a standard wet system into a more controlled "preaction" system. System Integration : The DSZ 3000 is often used in
, it serves as a critical interface for supervising and controlling deluge and pre-action sprinkler systems. Viking EMEA
In independent trials (DIN EN 12094-10 standard), the Dsz 3000 extinguished a 3B propane pan fire in 6.2 seconds (average) and a Class A wood crib fire in 22 seconds. Re‑ignition was prevented in 19 of 20 test runs. The system’s dual-zone isolation maintained agent concentration above minimum design density for 10 minutes in the affected zone while leaving the adjacent zone untouched.
The deployment of the Minimax DSZ 3000 and matching pre-action systems is prioritized across high-value commercial and industrial applications where clean, dry conditions are mandatory: System Integration : A single pre-action unit contains

is a specialized, compact monitoring panel engineered by Minimax to supervise advanced pre-action sprinkler configurations, such as the Gemini and DS21 double-head sprinkler systems. By providing precise electronic supervision, this control unit effectively prevents accidental water discharge due to false trips or mechanical damage, making it a cornerstone component in modern high-safety fire suppression systems. Technical Specifications and Part Numbers
The DSZ 3000 operates on a two-step "preaction" process to prevent accidental water discharge, which can be as damaging as a fire in sensitive environments.
In the demanding field of fire protection, reliability and speed are paramount. The Minimax DSZ 3000 monitoring panel represents a critical component within specialized, high-performance fire extinguishing systems. Specifically designed for preaction sprinkler systems, the DSZ 3000 offers advanced control and monitoring capabilities, ensuring that water-based suppression is delivered only when and where it is needed.
