Choose the Right Fire Door Retainer

Type	Best for
24V DC electromagnetic	Hard-wired fire-alarm/control systems using a low-voltage supply.
230V AC electromagnetic	Hard-wired installations where a suitable 230V supply and control arrangement is specified.
Dorgard DG2000	Battery-powered acoustic hold-open where hard wiring is undesirable and the alarm is clearly audible.
Dorgard SmartSound	Busy or noisy buildings where enhanced sound recognition helps filter everyday background noise and reduce nuisance releases.

Hard-Wired Electromagnetic Fire Door Holders

Electromagnetic retainers hold a compatible self-closing fire door open while energised. When the fire alarm or control equipment removes power, the magnet releases and the existing door closer returns the door to the closed position. Choose the correct voltage and mounting style for the installation.

The range includes surface-mounted models for straightforward installation and flush-mounted Geofire Conquest models designed around a suitable electrical back box. Floor mounting on compatible products is achieved using the appropriate bracket rather than by treating a standard wall-mounted retainer as a floor model.

Dorgard & SmartSound Acoustic Retainers

Fireco Dorgard products are different from magnetic door holders. They are battery-operated acoustic retainers fitted to the door and listen for the building's fire alarm. This can make them useful for retrofit projects because there is no hard-wired connection to the fire alarm panel.

SmartSound adds enhanced noise filtering. It is designed to distinguish a compatible fire alarm from common background sounds such as vacuum cleaners, machinery and general building activity, helping reduce nuisance releases in busier environments.

Mounting & Accessories

Choose from surface or flush electromagnetic holders, floor mounting brackets, chain armatures and chain keepers to suit the doorway geometry. Always confirm compatibility between the retainer, mounting accessory, door closer and the complete fire-door assembly.

For hard-wired installations, also see our power supply units, switches and fire alarm activation equipment.

Fire-door hold-open equipment should be specified, installed, commissioned and maintained in accordance with the manufacturer's instructions and the building's fire strategy and risk assessment.
