Information About 4-PPS/M
The 4-PPS/M is a high-performance primary power supply module designed for use in Edwards EST3 and EST4 modular fire alarm control systems. It provides 7 amps of clean, regulated DC power and distributes energy efficiently through the local rail, ensuring reliable operation of user interface modules and system components. With two 3.5 amp auxiliary power-limited outputs, it supports additional devices while maintaining safety compliance. Its switch mode design, parallel supply capability, and automatic battery testing make it both efficient and dependable for modern life safety installations.
Key Features:
- 7 Amp Regulated Power Output: Delivers continuous, stable 24 VDC power to system modules and peripheral devices without voltage fluctuations.
- Dual Auxiliary Outputs: Provides two independent 3.5 amp power-limited outputs for additional equipment such as detectors, notification appliances, or interface devices.
- High Efficiency Switch Mode Design: Enhances performance by reducing energy loss and minimizing heat generation during extended operation.
- Shared Power Rail Distribution: Integrates into the EST system’s local rail to distribute power across multiple modules and user interface cards.
- Parallel Power Supply Support: Can be paralleled with other supplies to deliver up to 28 amps of capacity within a single node for high-demand applications.
- Integrated Battery Charger: Features dual-rated, temperature-compensated charging to maintain optimal battery performance and extend service life.
- Automatic Battery Load Testing: Continuously tests standby batteries under load to ensure readiness during power outages.
- Safety and Compatibility Protection: Designed specifically for EST3 and EST4 systems, and must not be mixed with legacy 3-PPS/M, 3-BPS/M, or 3-BBC/M units to prevent damage.
- Compact Modular Installation: Occupies one wallbox footprint and one local rail slot, simplifying installation in both new and retrofit systems.
- Compliance with Safety Standards: Fully approved to UL and ULC requirements, ensuring adherence to fire safety codes.
The 4-PPS/M delivers the reliability and precision required for stable power distribution and battery management in Edwards EST3 and EST4 life safety systems.
