Dorgard Fire Door Retainer

Dorgard Fire Door Retainer - Electromagnetic Door Holder

The Dorgard fire door retainer allows fire doors to be held open in a safe and legal manner, whilst ensuring that the door will close in the event of a fire.

The door can be held open at any angle and a rubber plunger keeps it in place through constant contact with the floor.

The Dorgard has a built in audio-electronic device which will cause the plunger to retract when the fire alarm is activated, thus closing the door and ensuring fire safety is maintained.

As a green initiative, Dorgard no longer supply the floor mounted foot as standard. If one is required, you will find a card with QR code in the box - scan this and a free of charge foot will be supplied.

The Dorgard Fire Door Retainer - A Closer Look

The Dorgard door retainer is an innovative product designed to hold open fire doors legally. It provides a reliable solution for easy access while maintaining the highest level of fire safety.

This unit features a sleek and compact design, making it suitable for a variety of facilities and door types. With its intelligent technology and user-friendly operation, the Dorgard offers a practical and efficient solution for any fire safety plan.

Dorgards are ideal for areas where an electromagnetic door closer cannot be installed. They are not hardwired so cost and time effective to install in conjunction with existing fire alarm systems.

Superior Performance and Compliance with EN 1155

The Dorgard acoustic retainer is manufactured to the highest industry standards, ensuring superior performance and reliability. It complies with EN 1155, the European standard for electromagnetic hold open devices.

It is effective in preventing the spread of fire and smoke. When a fire alarm sounds, the unit releases the door automatically, allowing it to close.

Door holders are frequently installed in education and healthcare facilities including schools and hospitals, providing flexibility and accessibility.

Ensuring the safety of occupants in any building is of utmost importance. Fire door retainers play a crucial role by holding open fire doors securely, allowing for easy movement and access throughout the building while preventing the spread of fire and smoke. The Dorgard excels in both functionality and performance, making it an ideal choice for any fire safety application.

Easy Installation and Operation

Installing the Dorgard fire door retainer is a hassle-free process that requires minimal effort and time. It can be easily installed on any fire door without the need for complex wiring.

The retainer is attached to the bottom of the door and requires simple calibration to ensure proper functionality. Its intuitive design and user-friendly features make it convenient to use for building users, reducing the chances of doors being wedged open.

The fire door should have a separate controlled door closer fitted prior to the retainer being installed. Various other criteria also need to be met so view or download the fitting instructions below for more details.

Tools required for installation:

• Screwdriver
• Bradawl
• 3mm drill bit and electric drill (if the unit is being installed on top of the door's kickplate)

Night Time Release - Enhanced Security and Safety

In addition to its fire safety capabilities, the Dorgard fire door retainer offers a unique night time release function. This feature allows the door to close automatically at a preset time, providing an extra layer of security during non-operational hours. The hold open function will not re-engage until a set time the next day.

The night time release ensures that fire doors are closed and secured when the building is unoccupied. This helps in maintaining the overall security and fire safety of the premises.

The different automatic night time release functions can be set using the dip switches on the back of the unit. The unit also carries out a self-test every 7 days, emitting an audible beep pattern if any faults are detected.

Innovative Design for Maximum Convenience

The Dorgard acoustic door retainer incorporates innovative design elements that prioritise user convenience. One notable feature is its contact with the floor, which enables the retainer to detect obstacles and avoid accidental closures.

This intelligent mechanism ensures that the fire doors remain open only when it is safe to do so. This prevents any potential hazards while maintaining the necessary hold open functionality.

If the door is very heavy or has closing forces in excess of 120 Newton Metres, then the floor plate will need to be installed. The floor plate when installed correctly, prevents the door from slipping closed.

Durability and Longevity

Built to withstand the rigors of daily use, the Dorgard is constructed from high-quality building materials, ensuring its durability and longevity. The robust design allows it to endure heavy foot traffic and impacts, making it suitable for demanding environments.

With proper maintenance and regular inspections, the retainer will provide years of reliable performance, giving you confidence that your fire safety measures are in place. Weekly, monthly, and six-monthly maintenance checks should be carried out.

It is recommended that the battery is replaced every 6 months. However, a visual and audible indication of low battery status and a series of beeps for possible faults provide peace of mind year round. This unit is supplied with 2 x C size alkaline batteries. Rechargeable batteries should not be used.
