Identifiers
In access control systems each user has a unique RF ID. Identifiers can take the
form of a plastic card, key FOB etc.
Reader
The information on the identifiers is read with READERS, connected or built-in to the
ACS control panel. U-Prox IP500 Smart Handle has built-in reader.
Access point (AP)
Access point is a logical concept of the access control system implying control of
passing through a door in one direction. It consists of reader, access control panel
(or its part), door supervision devices (like door contact, RTE button etc.) and door
locking device. For instance, the turnstile with two-way passes has two Access
points
– one for entrance and the other one for exit, door of this type is called
double-sided door. A door with a reader on one side has only one Access point
–
Entry point, and it is called single-sided door.
Direction of passage
Passageway - is a logical unit of ACS, controlling passage through the access point
in one direction. It includes reader, access control panel (or part of access control
panel), actuator. So, tourniquet with double-sided control has two passageways, and
the door, having single-sided reader - only one passageway. Access point, which
consists of two passageways, is called double-sided, and the point of access, which
consists of one direction of passage - single- sided.
Door contact
Properly designed ACS is used to supervise door status (opened or closed), such as
magnetic door sensor, sensor of the turnstile rotor position, inductive sensor of the
road barrier, etc.
This ensured that the system prevents situations when several users access the
door with one
RF ID or door left open after user’s access and so on. For these
purposes the magnetic sensor of door closing, position sensor of the turnstile rotor
and the position sensor of boom barrier are connected to the input of access control
panel. The input used to connect these sensors, is called the input of sensor of
passage (or Door Contact)
Normally panel supplied with Door Contact switched off. To use Door contact install
Request-To-Exit microswitch and turn Door contact supervision ON.
RTE (request to exit)
To unlock the door and exit from the premises turn the inside handle.
Normally panel supplied without installed Request-To-Exit sensor. In this case you must
adjust Request-To-Exit microswitch as shown in paragraph "
Request-To-Exit contact
