LifeSafety Power FlexPower RD250/250-16 Power Supply User Manual

1. Product Overview

The FLEXPOWER RD SERIES is a versatile 12/24VDC single or dual voltage, DC rackmount power system. It features multiple power distribution outputs, specifically engineered for critical applications within the access control, security, CCTV, and mass notification sectors of the life safety industry.

This unit simplifies power distribution for auxiliary equipment, offering various output configurations. Models designated with '/E' are factory-preset for a 230VAC input. The system provides options for two, eight, or sixteen continuous or switched power outputs. Each output is individually fused at 3A (or 5A for 'H' variants) and includes robust protection against electrical surges caused by lightning or transient events on external wiring, thanks to its integrated SurgeShield technology.

Users can select between 12VDC or 24VDC operation (with 12VDC as the factory default). The switched power outputs are user-configurable for either failsafe or failsecure (ON-OFF) operation, which activates upon initiation of a fire alarm input. The factory default setting for switched outputs is failsafe.

This image displays the LifeSafety Power FlexPower RD250/250-16 power supply unit. It is a black, rectangular, rack-mountable device. The front panel features the 'LifeSafety Power' logo and two rows of green LED indicators, numbered 1 through 8 and 9 through 16, plus an 'F' indicator, signifying the status of its multiple power outputs.

2. Setup and Installation

2.1 Unpacking and Inspection

Carefully remove the power supply from its packaging. Inspect the unit for any signs of physical damage that may have occurred during transit. Report any damage to your supplier immediately.

2.2 Mounting the Unit

The RD250/250-16 is designed for rack-mounting. Secure the unit into a standard equipment rack using appropriate rack screws. Ensure adequate ventilation around the unit to prevent overheating.

2.3 Power Input Connection

Connect the power supply to a 120V AC power source. For '/E' models, ensure a 230VAC input is provided. Use a grounded power outlet. Refer to local electrical codes for proper wiring procedures.

2.4 Output Voltage Selection

The unit is selectable for either 12VDC or 24VDC output. The factory default setting is 12VDC. Consult the internal jumpers or switches (refer to the detailed wiring diagram in the full product manual, not included here) to adjust the output voltage if 24VDC is required for your application.

2.5 Connecting Output Devices

Connect your access control, security, CCTV, or mass notification equipment to the designated power distribution outputs. Each output is fused at 3A (or 5A for 'H' variants). Ensure the total current draw of connected devices does not exceed the unit's maximum capacity.

3. Operating Instructions

3.1 Powering On

Once all connections are secure and verified, apply AC power to the unit. The front panel LEDs will illuminate to indicate the status of each output.

3.2 Output Status Indicators

The front panel features LED indicators for each of the 16 outputs (1-16) and an 'F' indicator. A lit LED typically signifies that the corresponding output is active and providing power. Refer to the full product manual for specific LED status interpretations.

3.3 Failsafe/Failsecure Operation

The switched power outputs can be configured for either failsafe or failsecure operation. This setting determines the state of the outputs (ON or OFF) when a fire alarm input is initiated. Failsafe typically means the output de-energizes (turns off) during an alarm, while failsecure means it remains energized (stays on) or energizes during an alarm. The factory default is failsafe.

3.4 Fire Alarm Input

The unit includes a dedicated input for integration with a fire alarm system. When this input is triggered, the configured failsafe/failsecure operation for the switched outputs will activate.

4. Maintenance

The LifeSafety Power FlexPower RD250/250-16 is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance.

• Ventilation: Ensure that the ventilation openings on the unit are clear and unobstructed to allow for proper airflow and heat dissipation.
• Connections: Periodically inspect all power input and output connections to ensure they are secure and free from corrosion.
• Cleaning: If necessary, gently clean the exterior of the unit with a dry, soft cloth. Do not use liquid cleaners or solvents.
• Fuse Replacement: In the event of an output failure, check the individual fuse for that output. Replace blown fuses only with fuses of the same type and rating (3A or 5A for 'H' variants). Always disconnect AC power before replacing fuses.
