Fireco Dorgard DG2000 Fire Door Hold Open Device with Flat Floorplate (3 Colour Variants)

The Fireco Dorgard DG2000 is a self-contained, battery-operated acoustic fire door retainer that keeps a self-closing fire door open during normal use and automatically releases it when the fire alarm sounds. By allowing the existing door closer to close the door when required, it provides a practical alternative to unsafe wedges while improving movement, ventilation and day-to-day access around the building.

This version is supplied complete with a standard flat floorplate. The plate gives the Dorgard plunger a defined contact point and is particularly useful where a smooth or slippery floor, repeated door positioning or the door closer's operating force calls for a more positive location.

How the Fire Door Retainer Works

Open the fire door to the required position and press the foot-operated plunger to retain it. The DG2000 continually listens for a sustained alarm signal at around 65dBA or above. Once a suitable alarm has sounded continuously for approximately 14 seconds, the plunger releases and the existing self-closing mechanism shuts the door. Adjustable sensitivity and the timed night-time release function help the unit suit everyday operating conditions.

Key Features

• Automatic alarm release: Allows the existing door closer to close the fire door when a compatible fire alarm is detected.
• Wire-free installation: Self-contained C-cell battery power removes the need for mains wiring or a cable connection to the fire alarm panel.
• Adjustable alarm sensitivity: Can be set to respond appropriately to the alarm sound level at the installation location.
• Standard flat floorplate included: Provides a low-profile contact surface for the plunger on smooth or slippery floors.
• Flexible hold-open position: The foot-operated plunger can retain the door at the angle required for the opening.
• Straightforward fitting: Fixes to the bottom of a suitable internal fire door using four screws; typical installation takes around five minutes.
• Heavy-door suitability: Suitable for compatible door leaves up to 160kg and 1,600mm wide, up to power size EN7.
• Night-time release: Automatic timed release helps doors return to the closed position outside normal working hours.
• Accessibility and circulation: Reduces the effort of repeatedly opening heavy self-closing doors for staff, residents, visitors, wheelchairs and trolleys.
• Robust construction: Durable ABS housing, practical manual foot operation and a choice of colour finishes.

Technical Specifications

Installation and Compatibility

• Designed for suitable internal self-closing fire doors; the door must already have an effective, compatible door closer.
• Mount the unit at the bottom of the door using the supplied fixing points, ensuring the plunger can meet the finished floor correctly.
• Secure the supplied flat floorplate in the correct position where a defined plunger contact point is required.
• Check that the door closes fully and latches or seals correctly when the hold-open device releases.
• Commission the unit against the building's actual fire alarm sound level and operating conditions before the doorway is brought into service.
• Use only where the device is appropriate to the site's fire risk assessment, fire strategy, door certification and applicable installation category.
• Inspect, test and maintain the retainer and its batteries in accordance with the manufacturer's instructions and the building's fire-door maintenance regime.

Recommended Applications

• School and college corridors where pupils, staff and equipment need convenient movement through fire doors.
• Care homes, supported-living buildings and healthcare premises where heavy doors can restrict accessible circulation.
• Hotels, guest accommodation and apartment communal areas where doors must close reliably when the alarm operates.
• Offices, community buildings and busy commercial premises requiring easier access and improved ventilation.
• Refurbishment or retrofit projects where installing a hard-wired hold-open device would be disruptive.
