Eversecu 24V 5A 120W Fire Alarm Power Supply
The Eversecu unit provides an uninterruptible backup function for fire alarm and related devices. When AC power fails, it seamlessly switches to an attached battery (battery not included) to maintain operation of critical components such as fire dampers, smoke vents, indicators, and gates. The design supports a 24VDC output with a 120W power rating, accommodating multiple heavy-duty security peripherals.
Key features include intelligent battery charging with a maximum charging current of 800 mA and a maximum charging voltage of 27.6V. The controller supports pairing with two 12V batteries in series or two 24V batteries in parallel (batteries not included). The unit’s high-power output and backup switching are suited for systems requiring reliable operation during outages, making it a practical choice for larger facilities or multi-device configurations.
2gig AC1 AC Switching Power Supply
The 2GIG AC1 is a dedicated replacement power supply for 2GIG security systems. It accepts input from standard 100-240 VAC 50/60 Hz power and provides a steady 14.0V output. This module is designed to integrate cleanly with existing 2GIG ecosystems, helping ensure reliable operation of alarms and ancillary components during power interruptions. Its straightforward design makes it a practical upgrade or spare for compatible systems.
Altronix ACM Series Access Power Controllers
Altronix ACM Series combines eight fused outputs with a built-in power supply/charger. It provides 12/24 VDC options and offers protective features such as short circuit protection and thermal overload protection. Each of the eight outputs is fully fused and can be managed to support various devices within a fire alarm or access control system. This model is ideal for facilities needing distributed power across multiple peripherals with centralized monitoring and protection.
Altronix AL175ULX Power Supply/Charger
The AL175ULX provides two output channels with 12VDC or 24VDC at 1.75A per channel, offering Class 2 power-limited outputs. It includes a built-in charger and an optional fire alarm disconnect feature (latching or non-latching). The compact enclosure measures 13.5 inches in height and 13 inches in width, making it suitable for mounting in constrained spaces while delivering reliable dual-output power for alarm devices and controlled access components.
AccessShield Fire Alarm Power Box
The AccessShield DC power box is designed for emergency power needs in security and intercom systems. It lists a wattage of 42W and a current rating of 5A, making it suitable for smaller to medium-sized installations where a dedicated backup DC supply is needed to keep critical components online during outages. The device is branded for straightforward integration into existing control panels and door access networks, providing reliable backup power with simple deployment.
Buying Guide: Key Purchase Considerations
When selecting a fire alarm power supply, consider the following factors to ensure compatibility, reliability, and long-term performance:
- Power Requirements: Assess the total wattage and current draw of connected devices, including alarms, dampers, indicators, and intercoms. Choose a unit with a comfortable margin above peak requirements to handle surge currents.
- Voltage and Output Options: Verify whether the system requires 12V, 24V, or dual-output capabilities. Some devices may need adjustable output or multiple rails for different peripherals.
- Backup and Battery Management: If uninterruptible operation is essential, ensure the unit supports battery integration with safe charging profiles. Check battery chemistry compatibility (sealed lead-acid, AGM, LiFePO4, etc.).
- Safety and Protection: Look for short-circuit protection, thermal overload protection, and regulatory compliance. These features protect both the equipment and the facility during faults.
- Discreet Form Factor: Installers often need compact enclosures or mountable designs to fit equipment rooms, ceilings, or wall spaces without obstructing egress routes.
- System Compatibility: Ensure compatibility with existing alarm panels, access control devices, dampers, and intercoms. Some manufacturers offer integrated modules or disconnect options for streamlined integration.
- Maintenance and Monitoring: Favor power supplies with status indicators, remote monitoring options, and straightforward replacement parts or battery assemblies to minimize downtime during service.
- Warranty and Support: Check manufacturer warranties and access to technical support. A robust warranty is valuable when reliability is mission-critical.
Different facilities have different priorities. For hospitals and fire stations, backup reliability and rapid fault isolation may outrank compact size. For office buildings or campuses, modular multi-output configurations and easy expandability can drive choice. Weighing these trade-offs against installation constraints will help identify the most suitable power supply solution for your fire safety ecosystem.
