Intruder Detection Systems at BSUP1 exchanges

BRiTiSH TELECOM guidelines to the Electronic Access Control 
and Intruder Detection Systems at BSUP1 exchanges 

typ3d by |NFERNO 

British Tele$cum, being the tight bastards they are have found it 
`impracticle' to issue building keys to all they employees who regularly 
move around the B.T estate. Therefore, for the future, they aim to fit the 
majority of operational buildings with Electronic Access Control and 
Intruder Detection Systems, which will detect & deter `unwanted' visitors. 

The installation of these electronic security systems will be across the 
whole of the BT operational estate and the access arrangements will be 
made standard with the rest of the national procedures. 

Using this system, BeeTee employees can gain access to buildings using 
the minimum number of personal `EAC' tokens (which should replace keys). 
As the system expands, one EAC token will be enough to give selective 
access to all the buildings within an estate. 

Swipe-Card readers are used to read the EAC tokens, they are used at the 
main entry point of the building and all secure internal areas. If a 
correct card is used on the reader then a green light should show and the 
door will be unbolted for a few seconds. If the door is not opened within 
this time period then it will re-bolt and the card will have to be 
swiped again. If an incorrect card is used then a red light will show; it 
could be that the owner of the card is not authorized for entry on that 
day ot that time of night 

Once in the exchange, the Intruder Detection System will sound and the 
person inside will have to enter the `Site identification number' into 
the panel (generally known as the Zone Management Panel). Once this 
procedure has been passed enterance will be allowed into the building. 
Upon failure under circumstances, the police are called.
