Eversecu 24V 5A 120W Power Supply
Best for facilities needing a robust, high-current backup that seamlessly switches to battery power when AC fails. This model supports multiple heavy-security peripherals thanks to its 120W output and 24VDC range. The intelligent charging feature helps accommodate 2×12V or 2×24V battery configurations, though batteries are not included.
Who it’s for: facility operators with fire damper, smoke vent, and indicator networks that require reliable uptime during outages. Why selected: strong uninterrupted backup capability and compatible battery configurations improve resilience. Limitation: battery compatibility and installation require separate procurement and setup checks.
2gig AC1 AC Switching Power Supply
Best for 2GIG system users seeking a straightforward replacement power supply. It delivers 14.0V output and handles typical backup needs for smaller installations. This option is best for simple, compatible setups with existing 2GIG hardware.
Who it’s for: property managers upgrading older security panels. Why selected: direct compatibility offers a clean upgrade path. Limitation: limited output specifications may require additional capacity for larger peripheral loads.
Altronix ACM Series Power Controllers
Best for multi-output security panels needing integrated protection and regulated outputs. The ACM series provides eight fused outputs with selectable disconnect options and built-in regulation, simplifying complex installations while protecting circuits from overloads.
Who it’s for: fire alarm installers or building engineers managing multiple loads. Why selected: modular, protected outputs reduce wiring complexity. Limitation: may require careful configuration to align with existing panels and fuse settings.
Altronix AL175ULX Dual Output Power Supply
Best for compact or space-constrained installations needing two outputs and a dedicated fire alarm disconnect. The AL175ULX offers 12VDC or 24VDC at 1.75A per output, with a bundled enclosure for easy mounting.
Who it’s for: small to mid-size facilities with dual-voltage needs and a requirement for a built-in disconnect feature. Why selected: compact form factor and dual-output versatility. Limitation: limited to two outputs, which may not cover all peripheral networks.
Power Supply Box, DC12V 5A Emergency Supply
Best for access control and intercom systems needing a compact DC12V, 5A emergency supply with integrated control capability. The unit combines power and control features in a single enclosure.
Who it’s for: facilities with combined access control and intercom requirements. Why selected: practical integration of power and control for streamlined installations. Caution: verify compatibility with existing intercom hardware and door control wiring.
Buying Guide
What to consider when choosing a fire alarm power supply:
- Output voltage and current: Ensure the supply matches your periphery (12V or 24V) and the total load. Higher current supports more devices but requires adequate wiring and fusing.
- Battery compatibility: If the unit supports battery backup, confirm compatible battery types and configurations (series/parallel) and understand the charging parameters.
- Isolation and protection: Look for short-circuit protection, thermal overload protection, and filtered/regulated outputs to protect sensitive devices.
- Number of outputs: Multi-output controllers simplify wiring for larger systems; balance the need for multiple circuits with enclosure space and cooling.
- Fire alarm disconnect features: Some models include selectable disconnects; verify these align with your fire control strategy and local regulations.
- Compatibility with existing systems: Check conformance with your fire alarm panel, dampers, and intercom or access control hardware for a smooth upgrade.
- Installation and enclosure: Consider the physical footprint and whether a wall-mount or rack-mount enclosure is required for your space.
FAQ
- What is the main purpose of a fire alarm power supply?
It provides reliable power to fire alarm devices and ensures continued operation during mains failures, often including battery backup. - Do these supplies require batteries?
Some models include battery backup capability (batteries not included in the listing), while others are designed for direct DC power or battery charging compatibility. - Can I mix different brands in one system?
Mixing brands is possible if voltages, currents, and electrical protections are compatible; consult a system designer to avoid overload or compatibility issues. - What safety features should I look for?
Short-circuit protection, thermal protection, filtered outputs, and properly rated fuses help protect both the power supply and connected devices. - Is a dedicated fire alarm power supply necessary for small systems?
For critical safety devices and downtime-sensitive peripherals, a dedicated supply improves reliability and reduces risk during outages. - How do I determine the right capacity?
Sum the current draw of all connected devices at the required voltage; choose a supply with headroom beyond the total to account for startup surges and aging.
