Information About PAD-3
The PAD-3 is a Siemens power extender module engineered for expanding fire alarm system capacity in commercial and institutional facilities. Each of its four NAC outputs is power-limited and rated at 3 amps, with flexible input control that supports steady, ANSI temporal, or synchronized strobe output modes. It is fully compatible with Siemens 24VDC notification appliances, including horn/strobes, horns, and strobes. Designed with ADA compliance in mind, the PAD-3 ensures sufficient power delivery for buildings requiring enhanced audible and visual notification coverage.
Key Features:
- High Output Power: Provides up to 6A of 24VDC regulated power.
- Four NAC Outputs: Each circuit rated at 3A and power-limited for safety.
- Flexible Control Inputs: Supports one or two inputs to control all outputs.
- Multiple Operating Modes: Can be configured for steady, ANSI temporal, or synchronized strobe outputs.
- Horn/Strobe Silence Function: Allows silencing of horns while maintaining strobe operation using a single wiring set.
- Compatibility: Works with all Siemens Fire Safety 24VDC notification appliances.
- ADA Compliance: Supplies extra notification power to meet accessibility standards.
- Compact Design: Designed for integration with Siemens fire alarm systems in commercial environments.
The PAD-3 delivers the reliability and flexibility required for expanding notification appliance circuits in modern fire protection systems.
