Information About PAD5-6A
The PAD5-6A is a UL 10th Edition and ULC-S527 listed addressable power-supply unit from Siemens’ advanced PAD-5 series. It is built to deliver dependable 24 VDC output for notification appliances and auxiliary devices, supporting both Class A and Class B circuits. The module seamlessly integrates with Siemens FP2011-U1 and FP2012-U1 fire alarm control panels, automatically communicating status and diagnostics for system monitoring. Featuring microprocessor-based control, battery supervision, and ground-fault detection, the PAD5-6A provides robust and compliant operation for commercial and industrial fire-protection systems.
Key Features:
- High Output Power: Provides up to 6A of 24VDC NAC and auxiliary power for connected devices.
- Circuit Flexibility: Supports four Class B or two Class A output circuits, expandable with optional PAD-5-CLSA module.
- Supervised Operation: Monitors battery, ground faults, and NAC integrity for continuous reliability.
- Advanced Synchronization: Built-in support for System Sensor, Wheelock, Gentex, and AMSECO strobes and coded signals.
- Expandable Configuration: Optional modules allow additional circuits and releasing functions (e.g., deluge, pre-action).
- Microprocessor Control: Flash memory-based firmware ensures fast, accurate diagnostics and easy upgrades.
- Comprehensive Compliance: Meets UL864 10th Edition, ADA, ULC-S527, and ULC-S576 standards.
- Multi-Module Mounting: Fits 2HU enclosures with clean integration into Siemens fire systems.
The PAD5-6A delivers the reliability and precision required for fire alarm power distribution and notification control in critical safety environments.
