Door access control restricts who can enter an area or room in a building or who can use a particular resource. Basic access control comes in the form of mechanical digital locks which can be found in the Locks & Security section of our website. When looking for a more comprehensive access control solution; products such as electronic keypads and proximity readers, are the ideal choice. Once a system is installed access is easily structured and supervised by use of credentials – cards/fobs – which can be managed by online or offline software depending on the system. Our brands include ACT, Vanderbilt (Bewator) and Paxton.
There are different elements that make up access control systems and various factors that need to be considered when making a decision on what products will be required. A specifier will need to evaluate the following:
Keypads are a very common product in access control systems. They range from light duty to heavy duty and many are IP rated so suitable for external use (rain covers or surrounds may be required if they are in an area where they are exposed to the elements). Keypads are good for areas where a low level of security is required. They are a basic and convenient product to use for door entry and a cost effective solution for standalone doors.
The codes on keypads can be changed either by moving jumpers within the unit or by electronic programming - depending on the model. Keypads with jumpers are limited to up to two codes, whereas the electronic keypads can accommodate up to 500 user codes.
Some keypads can also incorporate a proximity reader so entry can be made by either presenting a fob, a card or pin entry. Sometimes keypads can require both a pin entry and a fob for an added layer of security. There are also units that use the keypad in order to programme the token on the door such as the KPX2000 and ACT5E Prox. These types of keypads utilise RFID (Radio Frequency Identification) Technology. Fobs, Cards and Tokens contain electronically stored data which is read by a reader, if presented within a certain distance of it. These tags operate on a radio length of between 120 and 150kHz and are programmed to the reader within the keypad which has a similar radio wavelength. The tag can switch between a lower and higher relative load and this produces a slight change that the reader can detect and identify. The keypad then communicates with the lock that it recognises this and ultimately unlocks the door. Weigand Readers like the RD-26 also work in this way.
Access control kits are complete access control solutions for doors. Our access control kits have been put together to make it easier for our customers to find a solution for them. The only additional item required is a keypad or proximity reader or an additional exit button (dependant on what you want for the door in question). We can also provide tailored quotations for access control, regardless of the size of the job. Our technical team are happy to help and our customers love that they can call us when on site to provide installation advice.
We stock a good range of exit buttons; DDA compliant ones, Narrow Style ones, Green Domed and can also source custom made ones if you’re looking for something in particular.
Most access control systems will require an emergency break glass unit; just in case the electric locking fails to operate correctly. One of the only times that this device is not required is when there is a Fail Secure Electric Strike or when there is an alternative exit route or it has been signed off by an authority (mental health facilities etc.). We also stock dual units; incorporating a push to exit button and an emergency break glass.
We have a range of regulated power supplies in 12VDC and 24VDC that can house rechargeable battery backup if required. All Power supplies have built in surge protection and are available in 1-5Amp units.
Transformer Rectifiers do not require battery backup and are ideal for use with electromagnetic door closers and hold open magnets. In the event that a fire alarm is activated, the transformer switches off the supply output to the closers or hold open devices and allows the door to close. The fire alarm system needs to be interfaced or a fire relay such as the RLFIRE should be used.
Relays are a type of electrically controlled switches. They can have a variety of uses but ultimately are used in situations where isolation of a component in an access control system is required or within a circuit as a form of protection device, breaking the circuit should the current be too high.
If you have a wireless exit button, you will require a transmitter to emit a signal and a receiver to read it and communicate with access control on a door. The transmitter sits within the button itself. Some transmitters like the TX26-E1 have a radio control button that emits a signal to a receiver. These can be used in applications such as gates, doors, barriers and lights.
Key switches are beneficial in access control situations where an easy system override is required. Key switches are either momentary (the key turns back after it is released) or maintained (the key remains in either an on or off position until turned back). Key switches can be placed within reception areas to allow control of the door and entry into the area or in conjunction with automatic operators.
