Information About S54339-A5-A1
The S54339-A5-A1 is the PAD-5-MB main board for Siemens PAD-5 notification power extender units, engineered to expand notification capacity in X-Series modular fire alarm control systems. It connects directly to the P2 loop of a Siemens XDLC (Device Loop Card) and can support up to 32 interconnected PAD-5 units or expansion boards per loop. With one programmable address set through the Siemens DPU device programmer, the PAD-5-MB enables flexible and scalable notification power distribution. Its design incorporates advanced features such as Class A/B NAC wiring support, Class X isolation, onboard diagnostics, and temperature-compensated battery charging, making it a critical element in expanding large-scale fire alarm installations.
Key Features:
- Remote Auxiliary Power: Supplies additional power to notification appliances in Siemens fire alarm systems.
- Expandable NAC Support: Provides four Class A or eight Class B circuits with mix-and-match configuration.
- XDLC Loop Integration: Connects via P2 loop to Siemens Modular fire-alarm control panels.
- Addressable Programming: Supports one system address configured through the Siemens DPU programmer.
- Built-In Isolation: Class X wiring isolator enhances circuit fault tolerance.
- Battery Charging: Includes temperature-compensated charging circuits for reliable backup power.
- System Monitoring: Equipped with “trouble” relay outputs for remote supervision.
- Diagnostic LEDs: Provides clear visual indicators for status and fault conditions.
The S54339-A5-A1 delivers the reliability and scalability required for extending notification circuits in Siemens Modular fire alarm systems.
