Overview

Why Use Electromagnetic Door Holders

Electromagnetic door holders are the smart choice for facilities that demand both convenience and compliance. They keep doors open during daily operations, release automatically on alarm or power loss, and integrate seamlessly with fire alarm and building management systems. With 100 lb holding force, low current draw, and stainless steel durability, they deliver safety, efficiency, and long‑term value across healthcare, education, hospitality, commercial, and industrial sectors.

 

  • Fail‑safe safety for fire protection Electromagnetic door holders are designed to release instantly when power is removed or when a fire alarm triggers. This ensures the door closer returns the door to the closed position, preventing unsafe propping and restoring fire compartmentation. They are a code‑compliant solution for keeping fire doors open during daily operations while guaranteeing automatic closure in emergencies.

 

  • Everyday convenience and accessibility These devices provide hands‑free hold‑open functionality for carts, stretchers, wheelchairs, and high foot traffic. They eliminate the need for wedges or mechanical catches, reduce wear on door closers, and improve workflow in hospitals, schools, hotels, offices, and warehouses.

 

  • Durable stainless construction With a stainless steel housing, electromagnetic door holders resist corrosion and withstand frequent cleaning. This makes them ideal for hygienic environments such as healthcare facilities, food processing plants, and coastal buildings.

 

  • Integration with building systems Electromagnetic door holders easily connect to fire alarm panels, smoke detectors, access control systems, and building management systems (BMS). This ensures centralized monitoring, supervised release, and compliance with safety regulations.

Commercial Offices and Retail

  • Typical locations: main lobbies, conference rooms, retail back‑of‑house, loading docks, server room access doors (non‑secure).

 

  • Recommended usages: hold conference room doors open during meetings; keep lobby doors open for deliveries; hold back‑of‑house doors during stock movement; integrate with BMS for centralized control.

 

Hospitality and Leisure

  • Typical locations: banquet halls, kitchens, service corridors, laundry rooms, pool area service doors.

 

  • Recommended usages: hold banquet and ballroom doors open during events; keep kitchen service doors open for staff flow; allow housekeeping carts to pass while ensuring automatic closure on alarm.

 

Industrial, Warehousing and Logistics

  • Typical locations: loading bays, production line access doors, staging areas, maintenance bays.

 

  • Recommended usages: hold dock doors open during loading/unloading; keep production access doors open for material flow; integrate with safety interlocks and emergency stop circuits to release on hazard detection.

 

Transport Hubs and Public Buildings

  • Typical locations: airport concourses, train station platforms, ticketing halls, government building corridors, stadium service doors.

 

  • Recommended usages: hold crowd‑flow doors open during peak times; keep service corridors open for staff and equipment; ensure automatic closure during emergency alarms to control egress.

 

Laboratories, Cleanrooms and Food Processing

  • Typical locations: lab entry doors, cleanroom pass‑throughs, food prep and processing doors, cold storage access.

 

  • Recommended usages: hold doors open during equipment transfer while ensuring immediate closure on alarm to maintain containment; use stainless housing for hygiene and washdown compatibility.

 

Residential and Multi‑Family Buildings (Selective Use)

  • Typical locations: service corridors, laundry rooms, maintenance closets, accessible entryways in multi‑family complexes.

 

  • Recommended usages: hold service doors open during maintenance; provide ADA‑friendly hold‑open for assisted living common areas while ensuring automatic closure on alarm.

 

Benefits

  • Fail‑safe operation for fire safety Releases instantly when voltage is removed or when a fire alarm signal is received to ensure doors close for compartmentation and occupant protection.

 

  • Low power consumption and efficient operation Draws 125 mA at 12 VDC or 60 mA at 24 VDC, reducing load on UPS, fire panel circuits, and battery backups for energy efficient building systems.

 

  • Durable stainless housing for harsh environments Corrosion resistant stainless construction withstands frequent cleaning, washdown, and corrosive atmospheres in hospitals, food processing, and coastal facilities.

 

  • Strong holding force for reliable performance 100 lb holding force secures most interior and service doors, preventing accidental closures during high traffic or material handling.

 

  • Easy integration with building systems Designed to interface with fire alarm panels, access control systems, building management systems, and smoke detectors for centralized monitoring and supervised release.

 

  • Retrofit friendly and installer oriented Optional stainless surface‑mount box and standard mounting templates simplify retrofit installs on concrete, steel, and finished surfaces to reduce labor and downtime.

 

  • Improved occupant convenience and accessibility Keeps doors open for hands‑free movement of equipment, carts, and people while preserving automatic closure on alarm for safety and code compliance.

 

  • Lower lifecycle cost and low maintenance Simple electromagnetic design with few moving parts minimizes service intervals, reduces replacement frequency, and lowers total cost of ownership.

 

  • Scalable and configurable for large installations Low current draw and standard voltage options allow multiple units to be deployed on supervised circuits with coordinated wiring and centralized supervision.

Floor-mount

 

Overview Floor‑mount electromagnetic door holders are installed at floor level, making them perfect for heavy doors, wide openings, and industrial environments. Their robust design ensures reliable hold‑open performance even under demanding conditions.

 

Benefits

  • Heavy‑duty performance — ideal for larger, heavier doors with strong closers.

 

  • Fail‑safe safety — releases automatically on alarm or power loss for fire safety compliance.

 

  • Rugged construction — stainless housing withstands impact, dust, and industrial environments.

 

  • Flexible positioning — floor mounting allows installation where wall space is limited.

 

  • Retrofit friendly — optional surface‑mount boxes and accessories simplify upgrades.

 

Recommended usages

  • Warehouses and loading bays where large swing doors must stay open during operations.

 

  • Industrial production areas with heavy doors and frequent material handling.

 

  • Public buildings and transport hubs where wide corridor doors require strong holding force.

 

Flush-mount

 

Overview Flush‑mount electromagnetic door holders are designed to be recessed into the wall or frame, creating a clean, low‑profile installation that blends seamlessly with modern interiors. This mounting style is ideal for projects where aesthetics, space efficiency, and unobtrusive hardware are priorities.

 

Benefits

  • Discreet appearance — recessed installation keeps the holder flush with the wall or frame, maintaining a sleek architectural look.

 

  • Fail‑safe operation — releases instantly on alarm or power loss, ensuring fire doors close automatically for safety compliance.

 

  • Durable stainless construction — resists corrosion and supports hygienic environments such as hospitals, laboratories, and food processing facilities.

 

  • Space‑efficient design — perfect for narrow corridors or areas where protruding hardware could be a hazard.

 

  • Integration ready — connects to fire alarm panels, smoke detectors, access control, and building management systems.

 

Recommended usages

  • Healthcare facilities where unobtrusive hardware supports infection control and patient safety.

 

  • Corporate offices and hotels where architectural design demands a clean, modern finish.

 

  • Laboratories and cleanrooms where flush surfaces reduce dust accumulation and simplify cleaning.

 

  • Public buildings and schools where recessed hardware prevents accidental bumps or damage.

 

Surface-mount

 

Overview Surface‑mount electromagnetic door holders are designed for quick installation directly onto walls, frames, or floors without the need for recessing. They are the most versatile option, making them ideal for retrofit projects, temporary setups, or facilities where concealed mounting isn’t practical.

 

 

Benefits
