With an increasing number of buildings requiring access control systems, and as a result, more locksmiths seeing this area as a potential revenue stream, we talk to access control expert NIGEL GRAY at HOPPE UK about the questions he is most frequently asked.
Q1: If I have a large number of users for the system, what are my options?
A1: A lot of locksmiths are used to selling stand alone systems – a simple electronic lock and / or electric strike for a small office or residential project. But when there are hundreds or thousands of users, possibly across several locations of buildings, they can tend to panic.
What is needed is an online system with a centralised computer control which can handle as many doors (or turnstiles) as required. There is still a control at each entrance but they are controlled centrally. This allows total flexibility with regardsto allowing access through certain doors by certain people – but it also gives the possibility of recording an audit trail to show who has come through the door and when, and can tie in with the building’s alarm systems.
Q2: My client doesn’t want push button locks – what other sort can I use?
A2: The most common and popular access method now is proximity reader which users find very simple to use. But there is also the choice of swipe cards, and audio /video systems. More and more companies are also using biometric systems with fingerprint or facial recognition software. It really depends on what level of security is required and how much traffic will come through the portal. Anyone who has travelled on the London Underground using an Oyster Card will know just how fast and efficient a proximity reader system can be in situations in which there is a high level of traffic.
Q3: What kind of locking system should I go for?
A3: An electric strike is, of course the most common type of lock on a controlled door. But where the system is integrated with the fire alarm, a magnetic or solenoid lock is required. Where extra security is required, select a sheer lock or solenoid bolt.
Q4: I need to integrate the access control system with the building’s alarms – what can I do?
A4: Online access control systems can simply be integrated into the fire alarm systems, usually achieved by a Fire Interface Board. In this case, when the fire alarm is activated, the power is cut to the locks, and they automatically open (failsafe). This is most usually achieved using magnetic locks where all locks open in the event of fire, although in very sophisticated systems the power can be maintained on certain doors in order to retain security functions.
While a failsafe is the most commonly specified option, in some domestic settings, a fail secure option may be required, for example, when the power is cut, the doors will lock.
Q5: Can I include automatics in an access control system
A5: Yes you can! We have all used shop doors with an automatic option, often operated by a push button, on the door. But the same principle can be applied on domestic buildings designed for wheelchair users or other disabled people. In this case it might be necessary to adjust the parameters of the proximity reader to allow it to unlock and open the door from further away. Or even adjust the parameters for the reader differently on either side of the door – to work further away from outside but nearer inside.
Q6: what difference will different door materials make to the access control system?
A6: As well as the weight of the door and the level of security that metal doors imply, a steel door can sometimes cause problems with certain sorts of proximity reader, interfering with its efficiency, so you may want to opt for a different access method.
Q7: There’s only normal mains power at the door – what do I need to do?
A7: The power needs to be converted to a 12 or 24 dc supply so that it can – with a continuous (not alternating) current, operate a magnetic locking device.
Q8: What other systems can I link to the access control system?
A8: Modern technology means it is possible to link all sorts of other systems into the access control arrangements – clocking in and out at a commercial property, cashless vending systems in schools and colleges, audit trails in sensitive environments, for instance. The possibilities are limitless and switched-on locksmith s can extend their involvement in a project in many ways.
Q9: Where so I get help?
A: All reputable suppliers of access control systems have technical departments. Tap into their knowledge to tap into an important source of business.
