Activation Methods

There are many methods of activating a door.  The most common are motion sensors for fully automatic installations where the door opens as it is approached and low energy installations where the door is triggered by pressing a push pad.

We can mix and match activation methods for example, the door can open from the outside by pressing a push pad and open automatically from the other side via a motion sensor.  This configuration is particularly appropriate when the door fronts a pavement with lots of foot traffic which is not necessarily entering the premises.

For our disabled clients we offer a range of activation methods dependent upon their individual dexterity.  We have a number of hand held transmitters which vary in size and also larger button boxes for those with dexterity difficulties.  The button on the transmitter/box is pressed and the door will open automatically from either side.  We have also used blow switches, interfaces with environmental systems for severely disabled clients and, on one occasion, a bar code reader attached to the side of a wheelchair.

We also have a system which allows clients to unlock and open a door from anywhere in the world!

Access Control

The security of homes and businesses is more important than ever.  Access control basically means that only authorised people can gain entry to the building and any visitors are vetted before they are admitted.  Access control can take many forms and is tailored to the needs of the end user.  We can interface with existing access control systems and these can also be teamed with conventional activation devices.  For example the door could be fully automatic during office hours allowing anyone to enter and automatically switch to access control at an agreed time, say 5pm through a timer.  The door would then be locked and would only power open when a valid proximity tag was presented to the reader.

Normally a site will have a method for employees or residents to access the premises, usually a proximity reader or a key pad.  In addition, there will normally be a call point which visitors use to be identified; the door can then be unlocked and opened remotely usually by pressing a button on a telephone handset.

If movement around a secure building is needed, tracking software can be installed.  This records when a door was used and the identity of the person.

For sites with many users such as a sheltered housing scheme, a method of administering the issued access control tags can be difficult especially if there is no full time warden on the site.  Tags which have been lost or stolen need to be deleted from the system as soon as possible in order to maintain the security of the building and newly issued tags need to be enrolled on the system in order for them to operate.  London & Quadrant Housing Trust now have 23 installations in North London which we installed for them.  The system uses GSM technology which means that all the sites can be administered from Head Office without any requirement for telephone lines, computers or people at the sites where the proximity readers are installed.
