About this product

Union J-8755A-BLACK is a hold open device.

Application

Preventing a fire door from closing can land you in court and risks lives. But you still need a way to hold a fire door open for ease of access. DoorSense is the new way for you to keep a fire door open - and have it close if the alarm sounds, or at a set time.

A hold open door can provide important benifits such as easy of access and reduces touch points, preventing the spread of germs. DoorSense is a standalone unit which can be fixed to a fire door in seconds to provide a reliable way to keep it open - but will automatically release if the fire alarm sounds. DoorSense is incredibly easy to install, needing no wiring or special skills - it can even use the same footprint as some older units.

Once fitted, DoorSense is powered by two Alkaline C batteries for long working life, and has a Low Battery indicator to help you keep the unit in excellent working order. Once in place you can have it working manually or automatically via a timer to set a night release time, and then leave DoorSense to get on with the job of giving easy access while keep your staff safe. DoorSense is designed to be robust and practical.

A curved, fire-retardent casing helps to deflect impacts and stay looking smart even when subjected to extreme treatment, while the unit footprint allows it to be a direct retro fit for older fire door hold open devices. DoorSense is available in three colours: Black, Red and White, and comes supplied with full fitting and setup instructions along with batteries for instant startup.

Union J-8755A-BLACK hold open device

Union J-8755A-BLACK hold open device, Black

Who this is for

For the installer — this is the hold open device supplied under Union part number J-8755A-BLACK. Specify it by that part number.

The entries in the specification table are the ones held against this part number. Anything not listed there is not stated by us, and should be confirmed against the manufacturer's own documentation.

In plain English: this is a hold open device made by Union. The part number J-8755A-BLACK is the manufacturer's own code for this exact version of it.

Similar-looking items in the same family often differ only by a suffix on that code. If you are replacing something, match the code rather than the picture.

Buying this in the UK

We are a UK supplier and this hold open device is sold and shipped from the UK. Prices are shown in pounds sterling.

This item is returnable under our standard returns terms. Faulty goods are handled separately and are never affected by a returns restriction.

We do not quote a warranty term for this part. Every supplier-stated term we have checked against the manufacturer's own document has turned out to be wrong, so we would rather say nothing than say something we cannot stand behind.

Ask us and we will check it for you. Your statutory rights are unaffected.

Stock on this line moves, and lead times move with it. Ask us for the current position before you commit to a date on site.

Questions we get asked

Is this the exact hold open device I have been quoted? Check the manufacturer part number J-8755A-BLACK against your quote. That code is the only reliable identity for this item.

Can you check compatibility for us? Ask before you order and we will check it against the manufacturer's own documentation. We do not state compatibility that the record does not carry.

Why does the listing not answer every question? Because the specification held against J-8755A-BLACK answers some questions and not others. We would rather leave a gap visible than fill it with something we cannot show you.

What if I order the wrong version? Tell us the installation you are matching and we will work back to the part number with you. That is a faster conversation than a return.

Do you hold this in stock? Availability on this line changes through the week, so the honest answer is to ask us on the day. We will give you the current position rather than a general one.
