Lifesafety Power RGM75B-C4PZ/E Gemini Rack Mount

Lifesafety Power RGM75B-C4PZ/E Rack Mount Dual Voltage Power Supply with Battery Backup

Overview

The RGM75B-C4PZ/E is a 75W rack-mount power supply designed for access control systems requiring redundant battery backup and failsafe/failsecure lock control. Dual-voltage output (selectable by zone) supports both 12V and 24V door locks from a single unit, eliminating the need for separate power supplies in mixed-voltage deployments. The integrated fire alarm disconnect automatically unlocks doors on alarm activation, meeting life-safety code requirements. Built-in battery charger with low-battery cutoff protection prevents deep discharge, extending battery service life. Four independently programmable relay outputs (2.5A Class 2 each) allow fine-grained control over failsafe or failsecure lock configurations per zone, with optional dry-contact or voltage outputs.

Key Features & Benefits

• Fire alarm disconnect: Unlocks all controlled doors immediately on fire alarm signal, eliminating manual intervention during emergencies.
• Dual-voltage by zone: Programmable 12V/24V outputs per relay eliminate separate power supplies and reduce panel complexity.
• Battery backup with charger: Dedicated fast charger and low-battery cutoff prevent capacity loss and ensure failsafe operation during power loss.
• Enhanced surge immunity: Input and output protection guards against transient voltage events common in building electrical infrastructure.
• OutSmart dual-color LED: Visual status indication (green for 12V, blue for 24V) simplifies field troubleshooting without opening the enclosure.
• Remote monitoring (optional): Netlink module integration enables real-time power and battery status in a central dashboard; remote battery testing reduces site visits.

System Specifications

Power: 230VAC input, 75W total output. Form C fault contacts trigger on low/no battery, ground fault, supply failure, or blown fuse — integrate into monitoring systems or alarm panels to alert operations staff.
Outputs: Four 2.5A Class 2 power-limited relay outputs, independently programmable for failsafe or failsecure per zone.
Enclosure: 3.5H × 19.0W × 20.5D inches (3U rack-mount form factor). Weight 28.15 lbs. Designed for telecom cabinets or wall-mounted racks in server rooms or electrical closets.
Warranty: Lifetime manufacturer warranty reflects build quality and design confidence for long-term deployments.

When to Choose a Different Model

If you require higher output capacity (more than 75W across all zones), evaluate higher-wattage variants in the Lifesafety Power Gemini line. If you do not need fire alarm integration or battery backup, a simpler 12V or 24V power supply may reduce cost and complexity.
