Access Control BasicsEvery System needs a few basic components
Access Control systems use the same principle as a light switch. Power is wired into one end and when the switch is flipped power goes out the other end. The only real difference is Access Control systems contain circuit boards to apply logic. Understandably, people become confused about all the "hocus pocus" going on behind the scenes. Knowing a few basic ideas, however, relieves the confusion:

Electronic LocksSince the idea is to keep people out, electronic locks are in the ''locked'' mode 99% of the time. They will only unlock when a person gains access by properly presenting their code.
The big difference between the two locks types is a mag lock doesn't know if a person is inside the door or outside. It just holds the door closed. That is why mag locks require an additional piece of hardware on the inside of the door - an emergency release. This type of release comes in several forms: push button, motion detector, exit bar, etc.
Power SupplyPower supplies come in two types: power box and transformer. Transformers work well on simple systems, especially if they come in a kit where each component is specially designed to work together. However, when piecing together a system from scratch it is best to stay away from transformers. Not every component on the market can work with a transformer.
TimersTimers are the step child of access control systems. They are regularly ignored as most people concentrate on the big ticket items. But every system needs a Timer. It controls the unlock time of the door and even expensive power supplies do not come furnished with timers. They must be added to the power supply or somewhere else in the system. When added to a power supply, Timers are plug-in cards. When added elsewhere, timers can be either spliced into the wires or come with a component. Some electronic locks include timers, but not many. Some keypads include timers, but not many. If using a keypad, look at the Securitron brand as it is one of the few brands that include timers standard with most of their keypads.
Lock ReleaseBetter known in the industry as an ''input device'' these lock releases come in a hundred different forms. Keypads, card swipes, and prox readers are just a few of the common types.
So in the end, input devices are nothing more than signal senders. |
