Seco-Larm DH-171SQ Flush-Mount Magnetic Door Holder
The Seco-Larm DH-171SQ delivers 33 pounds (15 kg) of electromagnetic holding force for controlled door release and closing. It is designed for flush installation and pairs with Seco-Larm door closers to maintain automatic door control during alarms. This model is suitable for concealed or low-profile hardware needs in corridors or storage rooms where aesthetics matter. Best for facilities prioritizing a compact footprint and reliable fail-safe operation.
Best for: installations requiring a discreet, flush-mount solution that integrates with existing Seco-Larm closers. Better for: spaces where visible hardware is undesirable. Caution: ensure wiring routing accommodates flush installation to avoid clearance conflicts.
Seco-Larm DH-151SQ Magnetic Door Holder, Surface-Mount
This surface-mount magnetic door holder also provides 33 pounds (15 kg) of holding force, with no residual magnetism for clean release and fail-safe operation. Suitable for walls where surface-mounted hardware is preferable or required by structural constraints. It integrates well with Seco-Larm door closers for coordinated door behavior during alarms. Best for: easier retrofits on existing walls and quick installation. Caution: ensure wall surface can support the mounting hardware and electrical access.
Door Holder, Wall Mounted Strong Attachment for Fire Doors
This wall-mounted, strong-attachment door holder is designed to keep doors open during routine use and release immediately on alarm signals. It includes a MOV component to handle current spikes for longer life on active doors and provides a hands-free hold with a quick manual release option. Best for: corridors or entryways with frequent traffic and the need for rapid door closure in emergencies. Caution: ensure compatibility with door closers and alarm systems; some configurations may require additional wiring or mounting considerations.
Edwards Signaling 1509-AQN5 Electromagnetic Door Holder
Edwards Signaling’s 1509-AQN5 flush wall mount offers a compact, reliable option for electromagnetic door holding. While the listing specifies country of manufacture, the model is widely used in integrated safety systems where Edwards signaling products are deployed. Best for: facilities already using Edwards signaling ecosystems seeking a compatible door-holding solution. Limitation: check for specific system compatibility and mounting requirements in your building’s safety plan.
ZJchao Magnetic Door Holder with Manual Release
This model provides a strong hold with a manual override release, designed for emergency closure after smoke clears and automatic functionality during fire. It emphasizes a robust aluminum alloy build and a high suction force (up to 80 kg). Best for: heavier doors and smokeproof requirements where a higher hold force is beneficial. Caution: ensure the mount and electrical system can support the higher load and that manual release access remains convenient.
UHPPOTE Electromagnetic Door Holder (Basic, Flush)
UHPPOTE’s basic flush wall mount offers a standard 24VDC (typical) operation with dual voltage support (12/24 VDC) and a 50 kg (110 lb) holding capacity. It emphasizes low power consumption and anti-residual magnetism to ensure door release during fire alarms. Best for: budget-conscious projects that still require automatic release. Limitation: verify compatibility with existing alarm panels and conduit layouts.
Buying Guide: Key Considerations For Magnetic Fire Door Releases
- Holding Force: Match the door weight and size. Higher for heavy metal doors; lower might suffice for lighter interior doors.
- Mount Type: Flush, surface, and wall-mounted options affect aesthetics, wiring access, and retrofitting ease.
- Release Mechanism: Consider manual release availability and reliability during power outages and alarms.
- Activation System: Ensure compatibility with your building’s fire alarm system and door closer pairing for synchronized operation.
- Power and Voltage: Check voltage requirements (12/24 VDC) and power consumption for energy efficiency and backup plans.
- Durability and Materials: Aluminum alloy and robust housings help with long-term performance in high-traffic areas.
- Safety and Compliance: Confirm compliance with local codes and fire safety standards for door holders in commercial facilities.
- Maintenance: Favor designs with clear release mechanisms and easy access for inspection and service.
FAQ
- What is a magnetic door holder used for in fire safety?
– It holds a door open under normal conditions and releases automatically when the fire alarm activates, allowing rapid closure for safety. - Can these work with all door closers?
– They are designed to work with specific closers or system configurations; verify compatibility with your door closer model. - What mounting option is best for narrow corridors?
– Flush or surface-mount options are often preferred to minimize protrusions in tight spaces. - Is higher holding force always better?
– Not always; choose based on door weight, wind loads, and building traffic to avoid unnecessary strain. - Do these require professional installation?
– Professional installation is recommended to ensure proper electrical wiring, mounting, and compliance with safety codes.
