Seco-Larm DH-171SQ Flush-Mount Magnetic Door Holder
The DH-171SQ is a flush-mount magnetic door holder designed to work with Seco-Larm door closers to control door release and closing. It provides 33 pounds of electromagnetic holding force (15 kg) and uses fail-safe operation, ensuring the door releases when power is removed. Best for new installations where a clean, recessed look matters and where a reliable, wired hold-open function is required. It suits corridors, classrooms, and other interior doors where a subtle profile is preferred. A potential limitation is the need for proper wiring and concealment in flush installations.
Seco-Larm DH-151SQ Magnetic Door Holder, Surface-Mount
The DH-151SQ offers the same 33-pound holding force in a surface-mount package, making it ideal for retrofits where channeling into walls isn’t feasible. It’s a straightforward drop-in for Seco-Larm door closers, with no residual magnetism for smooth release and fail-safe operation. This is a solid choice for hallways and larger offices where a visible conduit or concealed mounting isn’t required. Limitations include surface visibility and potential cosmetic impact on the mounting surface.
Edwards Signaling Electromagnetic Door Holder, 1501-AQN5-1
The Edwards Signaling model is a recognized option for electromagnetic door holding, offering a robust design suitable for commercial environments. It is described as a durable unit (made in Mexico) geared toward consistent performance with fire door applications. Best for facilities that prefer established brands and need a reliable hold-open function that integrates with standard fire safety systems. A limitation is the lack of detailed force specifications in the provided data.
Generic Wall-Mounted Door Holder with Electro Magnetic Catch
This wall-mounted holder is designed for routine use in keeping fire doors open, with automatic release on alarm signals. It includes an MOV component to handle current spikes, promoting longer life for active doors. Best for hallways and entries where hands-free control is essential and where an explicit alarm-release feature improves emergency response. A note: as a generic option, consistency across installations may vary compared with brand-name products.
Fireco Dorgard DG2000 Door Hold Open Device
The Fireco Dorgard DG2000 is a compact, Bluetooth-enabled door hold-open solution designed for easy integration with smart building systems. It holds doors open in routine conditions and releases automatically when a fire alarm is triggered, supporting rapid emergency response. Best for facilities seeking wireless or simpler installation with automatic release features. A minor limitation includes reliance on onboard electronics that may require periodic maintenance for optimal operation.
Buying Guide
What factors influence the right magnetic door holder for fire doors?
- Hold force needs: Heavier doors require higher holding force. Evaluate door weight and traffic patterns when selecting a unit.
- Mounting style: Flush, surface, wall, or floor mounting affects aesthetics, space constraints, and retrofit ease. Choose based on ceiling height, wall finishes, and accessibility.
- Power and wiring: Wired (hard-wired) options generally offer consistent power. Wireless or smart options may provide easier installation but require battery management or network integration.
- Fail-safe behavior: Most devices release when power is removed. Confirm compatibility with your building’s fire alarm system and local codes.
- Reliability and maintenance: Established brands often provide clearer service paths and documented parts. For busy facilities, consider long-term support and ease of replacement parts.
- Environment and door type: Fire doors in public or high-traffic areas may need robust construction and resistance to impacts or tampering; ensure the unit suits wooden or metal doors and applicable door closers.
Practical Comparison Questions
- Which hold-open solution is best for retrofits with existing door closers? The DH-151SQ offers a surface-mount option that complements retrofit projects.
- What if I need the strongest hold for heavy doors? Look at units rated above standard 33 lb, such as wall/Floor-mounted options with higher holding force, like MOUMOUTEN’s model in dual 12V-24V configurations.
- Do I prefer a wired or wireless setup? Wired units typically provide steady power; wireless options may simplify installation but require battery/maintenance planning.
- Is automatic release critical for my building code? Devices with automatic alarm release, like the Generic wall-mounted option or Fireco Dorgard, are suited for emergency egress.
