Seco-Larm Enforcer Access Control DC Power Supply User Manual

1. Introduction

The Seco-Larm Enforcer EAP-5D5Q power supply is specifically designed for access control systems, providing centralized power for electronic locks and accessories. This unit integrates essential power sources into one heavy-duty, easy-to-install enclosure, replacing multiple individual power sources. It features robust fault response, supervision relays, and a built-in backup battery charger for enhanced system reliability.

2. Safety Precautions and Important Notes

• Batteries not included: Backup batteries must be purchased separately.
• Indoor Use Only: The Enforcer Power Supply is not waterproof or weatherproof. It must be mounted indoors where it will not be exposed to rain or other moisture.
• Qualified Personnel: Installation must be performed by qualified personnel.
• Code Compliance: All installation procedures should conform to local and all other applicable codes.
• Overload/Short-circuit Protection: The board is designed with overload and short-circuit protection, including automatic shutdown and an LED overload indicator.
• AC Input Fuse: Over-current fuse-protected AC input (3.15 Amps glass fuse).

3. Product Features

• Power supply for an access control system's electronic locks and accessories.
• Heavy-duty steel case protects the power connections.
• Ventilation holes prevent heat build-up.
• Built-in backup battery charger (backup battery is optional).
• Automatically switches to backup battery if AC power fails.
• Individual AC input and DC output LED status indicators.
• AC power failure supervision relay.
• Battery failure supervision relay.
• Selectable 2.2KΩ End-of-Line (EOL) resistor for AC failure and battery failure supervision relays via DIP switch.
• Selectable delay timer (5 sec., 5 min., 5 hours) for AC failure supervision relay via DIP switch.
• Field selectable for 12VDC or 24VDC output.
• Operating voltage input 110~240 VAC.
• Adjustable voltage range (11~15 VDC, 23~26 VDC) to compensate for voltage drop.

4. Setup and Installation

The EAP-5D5Q power supply is designed for easy installation within its heavy-duty steel enclosure. Ensure all installations are performed by qualified personnel and adhere to local electrical codes.

1. Mounting: Select an indoor location that is dry and protected from moisture. Securely mount the enclosure to a wall or suitable surface.
2. Access: The removable steel cover allows for easy access to the internal components for wiring and configuration.
3. Power Input: Connect the 110~240 VAC power input to the designated terminals. The unit includes a 6-foot power cord.
4. DC Output Configuration: The unit offers 5 outputs. Select the desired output voltage (12VDC or 24VDC) via the internal DIP switch. Adjust the voltage range (11~15 VDC for 12VDC setting, 23~26 VDC for 24VDC setting) using the VR switch to compensate for voltage drop.
5. Backup Battery Connection: If using backup batteries (not included), connect them using the provided battery leads. The enclosure has enough room for two 7AH batteries.
6. Supervision Relays: Configure the AC failure and battery failure supervision relays as needed. Select the 2.2KΩ End-of-Line (EOL) resistor via DIP switch if required. Set the AC-Fail relay delay timer (5 sec, 5 min, or 5 hr) via DIP switch.
7. Access Control Device Connections: Connect your electronic locks and other access control accessories to the appropriate DC output terminals.

5. Operating Instructions

Once properly installed and configured, the EAP-5D5Q operates automatically to provide stable power to your access control system.

• Power On: After connecting the AC input, the unit will power on.
• LED Indicators:
  • Green LED: Indicates AC input status.
  • Red LED: Indicates DC output status.
  • Flashing Red LED: Signals an output overload or short-circuit condition.
• Backup Battery Operation: In the event of an AC power failure, the unit will automatically switch to the connected backup battery (if installed) to maintain continuous power to the access control system.
• Fault Recovery: The system features auto-recovery; once an output short or overload condition is removed.

6. Maintenance

The Seco-Larm Enforcer Power Supply is designed for reliable, low-maintenance operation. Regular checks can help ensure optimal performance.

• Ventilation: Ensure the ventilation holes on the enclosure are not obstructed to prevent heat build-up.
• Environmental Conditions: Verify that the unit remains in a dry, indoor environment, free from moisture and extreme temperatures.
• Battery Check (if applicable): If backup batteries are installed, periodically check their condition and replace them according to the manufacturer's recommendations to ensure reliable backup power.
• Connections: Periodically inspect all wiring connections for tightness and signs of corrosion.

7. Troubleshooting

This section provides guidance for common issues you might encounter with your EAP-5D5Q power supply.

• No Power Output:
  • Check if the AC input Green LED is illuminated. If not, verify AC power supply and the 3.15A glass fuse.
  • Check if the DC output Red LED is illuminated. If not, ensure all connections are secure.
• Flashing Red LED:
  • A flashing red LED indicates an output overload or short-circuit condition.
  • Immediately disconnect devices from the outputs and inspect for shorts or excessive current draw.
  • The unit features auto-recovery; once the fault is cleared, the output should resume normal operation.
• No Backup Battery Operation:
  • Ensure backup batteries are properly connected and charged.
  • Check the battery failure supervision relay status.
  • Verify battery health; old or faulty batteries may not hold a charge.
• Supervision Relay Issues:
  • Verify DIP switch settings for EOL resistor and delay timer.
  • Ensure proper wiring to the alarm control panel or other integrated systems.
