Product Overview

Effective on doors up to EN power size 5, the DorMag Pro is the newest component of Fireco's Pro Fire Door Retainer System. These magnetic devices are connected in a network via the ProHub panel, and enable the safe and legal retention of fire doors to improve temperature control and ventilation. Promote ease of movement around the building, providing independence for children, older people and those with mobility impairments, while the height at which the units are fixed reduces the risk of tampering.

The ProHub is wired directly into the building's existing fire alarm system; when the fire alarm is activated, the ProHub sends radio signals to every unit in its circuit, causing them to close all fire doors. During day-to-day use, these units can be activated or deactivated manually at the press of a button, or remotely, if the system is connected to Fireco's InSite Site Manager software. The Fireco Pro Range system is suitable for any sized business, with the ability to control up to 500 connected fire door closers and retainers.

How It Works

Fireco ProHub

Fireco ProHub

At the centre of the system is the Fireco ProHub, which remains in constant radio contact with all connected Dorgard Pro retainers and Freedor Pro free-swing closers, allowing it to monitor their battery status and alert you of any faults. The InSite Site Manager cloud based remote management system gives you the ability to check the system status from anywhere. The ProHub is hardwired directly to your existing alarm panel and will send a signal to all Pro Range units wirelessly connected to the system when the fire alarm activates.

Upon receiving the signal from the ProHub the Pro Range retainers and closers will release, ensuring that your fire doors can close and prevent the spread of fire. There are two models of ProHub: 240V mains with optional backup battery, or Power over Ethernet (PoE).

Dorgard Pro Fire Door Retainer

Dorgard Pro Fire Door Retainer

A key component of Fireco's Pro Fire Door Retainer system are Dorgard Pro fire door retainers, which incorporate the latest components and technology. Available in black or white, the Dorgard Pro fire door retainer is constructed from tough and durable, impact resistant ABS plastic. Each unit is fitted with energy efficient elements, which enables the Dorgard Pro to last 1 – 2 years on a single set of batteries.

Freedor Pro Overhead Fire Door Closer

Freedor Pro Overhead Fire Door Closer

A completely wireless and battery operated free-swing fire door closer, the Freedor Pro takes the weight off and allows doors to be moved freely, and left open at any angle. This allows freedom of movement around a building for all occupants, but is especially beneficial to the mobility-impaired, children, and older people as closing a door for privacy no longer means struggling to open it again later. Available in silver, brass, gloss white, and matte black finishes.

DorMag Pro Magnetic Fire Door Holder

DorMag Pro Magnetic Fire Door Holder

The newest component of Fireco's Pro Fire Door Retainer system, DorMag Pro units use magnetic 'hold and release' technology to legally retain fire doors, while ensuring that they will deactivate to close the door in the event of a fire. These units rely on radio technology for emergency deactivation, preventing false activations from ambient sounds. Installation at the top of the door reduces the risk of tampering in public buildings. These units are constructed using durable ABS plastic, and can retain fire doors up to EN power size 5.

Fireco ProExtender

Fireco ProExtender

In a typical building the Fireco ProHub has an impressive 40-50m range, though the exact range will be influenced by the construction and function of your building. Our engineer will be able to assess the range of the transmitter within your premises, making recommendations bespoke to your requirements. The system's range can be increased on larger sites by adding Fireco ProExtender units. Up to 8 ProExtender units can be included in a system, with up to 64 Dorgard Pro and Freedor Pro units being interconnected into the system per ProHub / ProExtender. A maximum of 500 Pro Range retainers and closers can be connected and controlled by the system.
