Seco-Larm DH-171SQ Flush-Mount Door Holder
Holding force: 33 pounds (15 kg). This flush-mount magnetic door holder works with Seco-Larm door closers to control door release and closing. It features no residual magnetism for easy release and fail-safe operation, making it a solid choice for doors that require concealed hardware. Best for installations where a clean, low-profile look is important and where hard-wired operation is preferred.
Who it’s best for: Facility managers seeking a reliable flush-mount solution that disappears into the door frame, with solid integration to compatible Seco-Larm closers. Choose this if you want a high holding force without visible hardware and require fail-safe behavior.
Limitation: Requires compatible door closer and electrical wiring; ensure mounting depth matches flush-mount specifications for proper alignment with the door frame.
Seco-Larm DH-151SQ Magnetic Door Holder, Surface-Mount
Holding force: 33 pounds (15 kg). This surface-mount model mirrors the DH-171SQ’s performance but offers a surface-mounted footprint, which can simplify retrofits. It integrates with Seco-Larm door closers to control release and closing, with no residual magnetism and fail-safe operation.
Who it’s best for: Projects where a visible, easily accessible mounting surface is preferable or required due to wall geometry or retrofits. It’s a good pick when you want comparable holding force without concealment.
Limitation: Surface mounting can be more visually conspicuous than flush installations; verify wall material supports mounting hardware and force requirements.
Edwards Signaling 1508-AQN5 Electromagnetic Door Holder
Type: Surface wall mount. The model is designed for general surface mounting, offering robust electromagnetic hold-open operation. While specific holding force isn’t listed here, it is intended for standard door applications within Edwards Signaling ecosystems.
Who it’s best for: Buildings already using Edwards signaling products seeking straightforward surface-mounted door holding solutions with proven compatibility across Edwards components.
Limitation: Absence of explicit holding force in the data requires verifying performance with your door setup and closer pairing before install.
Edwards Signaling 1504-AQN5 Electromagnetic Door Holder
Holding force: 25 pounds (111 N) nominal. This flush-wall mount features die-cast metal construction with a baked polyester powder paint finish, offering durability for high-traffic doors. It provides a reliable hold-open function with a moderate holding force suitable for standard interior doors.
Who it’s best for: Environments requiring a sturdy, long-lasting flush-wall option with a balanced holding force that won’t overly tax door hardware. Suitable for hallways and interior doors where space near the hinge side allows flush mounting.
Limitation: Lower holding force compared to 33 lb models; confirm it meets your door’s sizing and fire-code requirements for egress paths.
Seco-Larm DH-100E-40SQ Extension Bar
Extension bar, 4″ long. This item is for use with DH-171SQ Flush-Mount and DH-151SQ Surface-Mount holders. Armature plate is sold separately and may be required to complete the assembly and ensure proper door-holding alignment.
Who it’s best for: Projects upgrading or expanding existing Seco-Larm door holders where extra reach or alignment is needed. Choose this when you already use DH-171SQ or DH-151SQ and require a longer arm to fit door dimensions.
Limitation: Extension bar is only a component; ensure you also have the appropriate armature plate and compatible mounting hardware for a reliable release.
Buying Guide
What to consider when choosing a fire alarm door holder
- Holding force: Common options provide 25–33 pounds of holding force. Higher force is better for heavier doors or wind-load scenarios, but may require stronger power supply and infrastructure.
- Mounting style: Flush-mount yields a discreet look; surface-mount is easier for retrofits but more visible. Choose based on door and frame aesthetics and space constraints.
- Fail-safe operation: Most fire-rated door holders are fail-safe, releasing during a fire alarm or power loss. Confirm compatibility with your building’s fire alarm system.
- Power and wiring: Ensure the control wiring and power supply meet local codes and the device’s electrical requirements. Hard-wired units demand proper electrical installation.
- Compatibility: If you use Seco-Larm or Edwards signaling ecosystems, pick holders designed to integrate with your existing hardware to ensure reliable release and release timing.
- Quality and finish: Consider die-cast or durable finishes for high-traffic areas and bathrooms or kitchens where moisture and abrasion can be issues.
- Maintenance considerations: Prefer units with simple electrical connections and easy access for service checks in routine inspections.
Installation vs retrofit considerations
- Flush-mount options hide hardware but require precise framing and alignment. They look cleaner but demand careful measurement before installation.
- Surface-mount options are more forgiving for retrofits but can require more wall space and visibility considerations.
- Extension bars help adapt door holders to unusual door widths or existing armature configurations; verify armature plate availability.
Code and safety alignment
- Door holders should release automatically when the fire alarm is activated, enabling safe egress without manual intervention.
- Ensure the selected model adheres to local fire and building codes and pairs with the door closer to avoid binding or delayed release.
FAQ
- What is the typical holding force for magnetic door holders? Most common models offer 25–33 pounds of holding force, suitable for standard interior doors.
- Do these holders require battery power? Many are hard-wired and powered by the building’s electrical system; some may use door closer power. Confirm the specific model’s requirements.
- Is a flush-mount always better than a surface-mount? Flush-mounts are more discreet and may be preferred in aesthetics-focused spaces; surface-mounts are easier to retrofit and service.
- Can I mix brands within the same fire alarm system? Compatibility is key. Use models designed to integrate with your existing closers and signaling equipment to ensure reliable operation.
- What maintenance is required? Regular inspections of electrical connections and mounting integrity help ensure proper hold-open and release behavior during alarms.
- Do these products meet safety codes? Each model is designed to work within standard commercial building safety frameworks. Verify local code compliance during procurement.
