Information About BPS6A
The BPS6A is a 6.5-amp model in Edwards’ BPS series of booster power supplies engineered for life safety and ECS/MNS applications. It provides four independently supervised NAC/AUX circuits (Class B or Class A) and two sense inputs for activation from an FACP or option modules. Built-in features include strobe synchronization for Genesis appliances, ground-fault monitoring, and configurable trouble relay behavior. A locking steel enclosure houses electronics and batteries, supporting on-board charging and straightforward field configuration via jumpers and DIP switches.
Key Features:
- 6.5 A Output Capacity: Delivers high current for notification appliances and system peripherals.
- Four Supervised Circuits: Configure as four Class B or two Class A NACs (field-selectable).
- Strobe Sync Support: Passes or generates synchronization for Genesis series strobes.
- Flexible Activation: Trigger from 12/24 VDC sense inputs or Edwards option modules.
- Integrated Battery Charging: Dual charging rates with on-board supervision and fault reporting.
- Comprehensive Diagnostics: Per-circuit trouble LEDs plus common trouble relay.
- Robust Enclosure: Keyed, lockable steel cabinet; supports internal or external batteries.
The BPS6A delivers the reliability and precision required for expanding NAC power, synchronized notification, and regulated 24 VDC distribution in life-safety systems.
