4. Control & System Functions

4.1 Multi-Stage Graded Alarm

The AH116-2 provides 4 independent remote trigger stages, which can be configured as normal warning, primary fault, secondary alarm and emergency danger levels. Different tones and visual frequencies can be matched for each stage, realizing hierarchical early warning and accurate hazard distinction, avoiding alarm confusion caused by single signal mode.

4.2 Multi-Unit Synchronous Linkage

When multiple AH116-2 units are networked in the same system, automatic synchronous sounding and synchronous flashing can be realized without additional synchronous controllers. The daisy-chain wiring structure greatly simplifies on-site wiring, improves system consistency, and is suitable for large-area factory buildings, offshore platforms and multi-area partition alarm systems.

4.3 Reliable Loop Adaptability

With dual inlet and outlet terminals, the unit supports series loop installation, compatible with mainstream fire alarm control systems and industrial PLC control loops. The built-in circuit monitoring function ensures real-time equipment status detection, meeting the requirements of unattended industrial safety systems.

5. Certification & Compliance

The AH116-2 series complies with a full range of international safety and quality standards, including CE, UKCA certifications, and meets industrial fire protection, marine engineering and process control specification requirements. All products are tested in accordance with EN industrial signalling standards, applicable for global industrial, marine and commercial safety projects.
