Most access control components use low voltage DC power, so a power source is required that converts the alternating current that comes into the building to direct current. Power is another important consideration. It is typical to have a mix of wiring types, including low-voltage wiring designed for security (such as 18-gauge shielded wire) and ethernet cable of the kind used for computer networks (such as Cat6). The choice of cable will vary based on the components used and the physical layout. Access Control Wiring & PowerĬomponents of the access control system require physical wiring for both communications and power. These are important choices for both safety and optimizing your security systems. Most electrified electronic hardware can be configured to either “fail safe” – default to open – or “fail secure” – default to locked – when power is not applied. For example, fire-rated doors require fire rated hardware. In all cases, locks must adhere to life safety and fire codes, so be sure to consult with a knowledgeable integrator on choice of locks, aesthetics, installation, and configuration. Mortise locks, installed in a mortise pocket of the door. Magnetic locks, which are typically mounted on the door frame above the door There are many different lock options to match the type of opening and the requirements of the access control system:Įlectric strike locks, installed in the frame of the doorĬylindrical locks, installed in the bored cylindrical pocket of the door itself Typically, openings connected to the access control system are protected by electric locking hardware, with a door position switch to monitor door open/close status. They are usually installed in an IT or communications closet. One panel is able to manage several doors, but in large buildings it’s typical to have more than one panel. This device checks credentials and grants access to individuals. In turn, RIMs are connected to an Access Control Panel, the local controller of the access control system. System Control HardwareĪll the equipment at an exit – the reader, the door position switch, the request to exit device – are wired to a Reader Interface Module (RIM) which relays the electronic hardware.
A second benefit to dual technology readers is that they can help to increase security based on two factor authentication for example, both what you have (an access card) and also what you know (a PIN). A benefit of this is that these readers can be used as the end user migrates to a different technology – such as moving from proximity technology to smart card credential technology.
