Controlled Electronic Management Systems Ltd ETHERPROX Manuel D’Utilisation

MAC Address: The unique 48-bit address burned into Ethernet and Token Ring adapters, 
identifying a specific network card from all others. The address is normally shown as 12 
hexadecimal nibbles, for example, 00-50-F9-3A-64-BC. 

NO/NC: Normally Open or Normally Closed contacts. 

PIN: Personal Identification Number used with cards to allow access. 

PIR: Passive infrared switch. Typically used for a REX. 

Power to secure: Indicates that a door is locked (secured) when the door strike relay is 
powered (engaged). 

Power to unlock: Indicates that the door is unlocked when the door strike relay is 
powered. 

Proximity: A type of reader (read head) that operates without a card actually touching the 
reader. The proximity reader uses wireless Radio Frequency (RF) technology. 

Reader: A door control unit that reads cards to allow access, which is one function of the 
unit. 

Relock delay time: The amount of time, in seconds, to delay relocking the door after a 
valid card access. Sometimes referred to as relock time. 

Relock time: see Relock delay time. 

Request to exit input: The input that monitors the Request to exit (REX or RTE) switch. 
The REX switch might be a pushbutton or PIR. This input is frequently placed on the 
secure side of a door to allow egress without a card read. 

REX: See request to exit. 

Site Code: An encoded three-digit number that differentiates one set of cards from 
another. The site code is embedded by the manufacturer of the cards, usually at the 
request of the user. 

Sounder: The piezoelectric device at the back of the reader from which sounds, such as 
alarms or confirmation beeps, emit: The Sounder is also referred to as the Sound Device. 

Standard door open time: See Door open time. 

Supervised input: An input that detects four states: normal, alarm, open circuit, and 
short circuit. 

Swipe: Present a card to the reader within the read range. 

System Number: The system number is an embedded card number; it appears in 
hexadecimal format on the door control unit LCD display. 

Tamper Sensor: A light-sensing device on the back of the reader unit that sounds an 
alarm when the unit has been tampered with. 

Time clearance: Configures access at specified days and times. 

Time zone: Configures access levels based on the time clearance.
