Lifesafety Power RGA75B-M8NZ Rack Mount Access Control Power System
Overview
The RGA75B-M8NZ is a UL-listed rack mount power solution combining a 75W power module with 8 managed output channels in a 3.5U form factor. Designed for access control systems requiring reliable failsafe/failsecure door control during power loss, this unit integrates battery backup, fire alarm disconnect logic, and remote monitoring into a single chassis—eliminating separate component procurement and reducing integration time on multi-door installations.
Key Capabilities
Dual voltage operation: Selectable 12V and 24V outputs per zone enable efficient lock powering without separate transformers, reducing heat dissipation and extending battery runtime on failover. 8 managed outputs at 3A per channel: Each fused output supports remote power cycling and programmable voltage/current monitoring—critical when diagnosing field lock faults without truck rolls. Fire alarm integration: Built-in Form C contacts automatically unlock doors on fire alarm signal, meeting life-safety code requirements. Battery protection: Low-battery cutoff prevents deep discharge cycles that degrade sealed lead-acid or lithium backup batteries, extending service intervals. Surge immunity: Input/output surge protection defends against lock solenoid transients and AC line spikes common in older facilities.
Monitoring and Control
The optional NetLink module enables remote battery health testing, temperature logging, tamper switch alerts, and email/SNMP notifications—allowing proactive maintenance before failures occur. OutSmart dual-color LEDs (12V green / 24V blue) indicate voltage presence per zone without serial console access. AC and system fault Form C contacts trigger integration with building automation or monitoring panels. Programmable cycle counting tracks lock actuation per zone to predict solenoid wear.
Physical Integration
3.5H × 19.0W × 20.5D inches fits standard 19-inch equipment racks. 28.65 lbs permits secure wall mounting or rack rail installation in telecom and security closets.
