Where doors in Northolt care homes, schools or offices are being wedged open, a hold-open device is the safe fix. We coordinate with your fire alarm contractor in Northolt so every hold-open releases when it should.
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.
What you get:
- Electromagnetic holders to BS EN 1155
- Release testing with the alarm
- Hold-open and free-swing closers
- Record of devices and test results

Questions from Northolt
Do you work in Northolt?
Yes, we take on fire door hold-open devices in Northolt and the surrounding area, including Greenford and Harrow. Send your postcode and a few details and we'll come back with survey dates.
Can you work from an existing inspection report for my Northolt building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
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.
Is it legal to wedge open a fire door?
Wedging a fire door open defeats its purpose and is likely to breach the duties under fire safety law. A hold-open device that releases on alarm is the safe alternative.
