Description

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.

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, fire­retardent 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.

TESTIMONIALS

What Our Customers Say

"I would like to send a big thank you to Miguel and the locksmith team for getting us out of a massive hole last week. We found out on Tuesday that we had a number of moves taking place which we had not been made aware of and I needed multiple keys by Thursday lunchtime. I am aware that they were short staffed but they fulfilled my order. Can you please extend to the whole team that I am indebted to them and very grateful. As always, excellent service."

J Savage - King's College London

"We had a complicated site in London for which we wanted a Masterkey solution. After discussing the project with a number of companies, Jim Caldwell of William Channon was the only person who seemed to understand exactly what we needed. After a very helpful site visit, all items were provided on time in stages as required and the fitting work was finished off by Oliver in a very professional style. Everything went smoothly and a solution was found for every problem. I would recommend William Channon for those needing a professional locksmith service and I would certainly go back to them again with future projects."

Louise - London SE1

"We approached William Channon earlier this year for advice as we were looking for ways to make the management of our student lockers more efficient. We were delighted that Terry was able to design a bespoke solution and to complete all the work needed to convert the lockers within a very limited timeframe during the summer vacation. The service we received was personal, professional and highly skilled and my team and I are incredibly grateful."

Gaynor Jones - Head of MBBS Management, UCL

"I could not be more pleased with the advice and service I have received from William Channon. From initial telephone contact, through survey, quotation and then installation, I have been impressed with the response and solutions to my awkward locks/keys/security issues. I can recommend it as a thoroughly professional company and one that has been a pleasure and relief to find and deal with."

Neil Thomas - Chairman of Falconbury Ltd

"...thank you very much for your help, we really appreciate it, you made this process so simple for us, it is lovely to experience such wonderful customer service."

Anna - London NW2

"Thank you so very much to you and Terry for giving me a wonderful service on ordering two very large chubb safes. I have never had to organise such a large project on this scale, where safes are concerned, and your company gave me the 100% commitment that I was looking for. I look forward to working with again."
