County Londonderry has a mix of buildings, from purpose-built blocks to converted houses and commercial premises. We tailor the programme to the building, not the other way round.
Types of hold-open
Electromagnetic door holders are wall or floor magnets wired to the fire alarm. Hold-open closers combine the closer and the hold-open in one unit. Free-swing closers let the door move freely and close it on alarm. Some battery units listen for the alarm sound; these must be suitable for the alarm system and the building. The right choice depends on the door, the alarm and how people use the space.

Fire door hold-open devices questions
Do you provide fire door hold-open devices across County Londonderry?
Yes. We cover all of County Londonderry, including Derry and Coleraine. Surveys and written quotes are free.
Do hold-open devices need the fire alarm?
Hard-wired devices are released by the fire alarm system. Some battery units detect the alarm sound instead; they must be suitable for the building and its alarm.
What is the difference between a hold-open and a free-swing closer?
A hold-open keeps the door at a fixed open position. A free-swing closer lets the door move freely, as if no closer were fitted, until the alarm sounds.
