Lockwood Concealed Fire Door Coordinator with Electromechanical Hold Open Silver FD484

Product code: FD484

The Lockwood 2616CO is a surface-mounted mechanical coordinator for double doors that are normally kept closed. The coordinator sits inside the covered slide rails; it holds the active leaf open until the inactive leaf is almost closed, then lets the active leaf close so the leaves close and latch in the correct sequence.

Door Closer Functions Explained

Door coordinator. On a pair of doors, the coordinator makes the leaves close in the correct order — it holds the active (passage) leaf open until the inactive leaf has closed, so both doors close and latch properly. It works alongside the door closers, not in place of them.
Hold-open. The door can be held open at a chosen angle and closes normally once released. Note: a mechanical hold-open must not be used on a fire door unless it is an approved electromagnetic (fire-alarm released) hold-open.
Non hold-open versions of this closer simply close after every use, and are the type required on most fire-rated doors.
Other functions offered across this closer range: Backcheck slows the door as it nears the fully open position so it can't slam into an adjacent wall (protecting the hinges, frame and wall) and delayed action holds the door open, or closes it slowly, for the first part of the swing to give extra time for wheelchairs, prams and trolleys. This model includes the functions listed above.

  • Successfully fire tested up to 4 hours on fire door assemblies to AS 1905.1:2005 – Part 1: Fire Resistant Doorsets.

How does the hold-open / coordinator work?

In normal use the door(s) are held open. When power is cut — for example when a smoke detector activates — the door releases and closes and latches. On double-door units a coordinator closes the leaves in the correct sequence.

Is it fire rated?

Yes. This family is fire tested on fire door assemblies to AS 1905.1:2005 – Part 1: Fire Resistant Doorsets. Check the Standards & Compliance section for the tested duration of this model.

Is it hard-wired?

The electromechanical hold-open runs on 24V DC (±15%, ~60 mA) and is wired into the building's fire-alarm/detection system so it releases on alarm.

What does hold-open mean?

Hold-open lets the door be parked open at a chosen angle and it closes once released. Important: a plain mechanical hold-open must not be used on a fire door — a fire door may only be held open by an approved electromagnetic (fire-alarm released) device, which drops the door shut automatically on alarm or power failure.

What is backcheck?

Backcheck slows the door as it nears the fully open position so it can't be flung into an adjacent wall — protecting the hinges, frame, closer and wall. It is a cushioning feature, not a hold-open, and is useful in windy or exposed locations. Only closers whose title lists backcheck have this fitted.

What is delayed action?

Delayed action holds the door open, or closes it very slowly, through the first part of the swing before returning to normal speed — giving extra time for wheelchairs, prams, trolleys or moving furniture. It is common in hospitals and aged care. Only closers whose title lists delayed action (DA) have this fitted.

Is this finish in stock?

Silver and Black finishes are normally held in stock with the supplier. All other finishes (and no-finish/raw components) are made to order — call Prime Hardware on 1800 329 028 to confirm availability and lead time before you order.

What warranty applies?

Lockwood products carry a 25-Year Mechanical Warranty against defects in materials and workmanship. Electrical/electronic components, where fitted, carry a separate electronic warranty. Manufactured by ASSA ABLOY Australia.
