ADT in the UK

ADT Fire and Security is also the British Government's primary security provider. All ADT employees are subject to in depth vetting due to the nature of information they have access to. Some ADT employees in the UK require Government SC Security Clearance from the Defence Vetting Agency.

About ADT systems

ADT's main service is the installation and monitoring of alarm systems, whereby one of their Customer Monitoring Centers (CMC) receives electronic signals from an alarm system when an alarm event is triggered, such as in the case of an intrusion, fire, carbon monoxide presence or manual depression of a holdup/duress button. A monitoring specialist examines the data received from the alarm system and determines the type of response the alarm signal warrants. Depending on the type of alarm, the monitoring specialist will attempt to contact the location via telephone to investigate further and determine if the signal is a false alarm. If necessary, the monitoring specialist can notify the local police, fire, EMS, or other emergency services department and/or an authorized security response service of the alarm status and the event address. ADT maintains seven Customer Monitoring Centers in North America.

Most consumers believe their ADT system is manufactured by ADT. In actuality, ADT security systems are generally manufactured by Ademco (a product of Honeywell International), GE ITI (both products of GE Security), DSC (a product of Tyco International), or Bosch. Fact|date=May 2008

In America in the 1800s; there were many small telegraph delivery companies; in 1887, 57 district telegraph delivery companies affiliated and became "American District Telegraph".


With the advent of advanced call boxes and multi-signal electric protection systems in the early 1890s, ADT gained a solid reputation in security protections.


With the increase in telephone usage in the late 1800s, ADT's messenger business slowly declined in popularity. ADT tried branching out and developing their signaling business while still maintaining their telegraph business as primary income source.


ADT incorporated into Western Union. Many developments were made this year in the now primary field of signaling. ADT separated its messenger business from its main signaling business.


Western Union (and ADT) came under the control of AT&T.


As technology improved and new ideas came into practice, ADT grew its business into new areas like fire alarms and burglar alarms.


With the Great Depression and World War II and the increased industrialisation they brought, security became more important to businesses. ADT grew and capitalised on this new age.


ADT becomes a publicly owned company. In 1964, ADT a division of the Grinell Company was found to be a monopoly in restraint of Trade. It was shown to provide almost 80% of the central station alarm service in the United States. In some cities, such New York City and Memphis, Tennessee, they were the sole provider of central station alarm service. They were also found to have forced out of business competitors by lowering prices below cost.

They would charge national accounts very low prices in cities with competitors and much higher prices where no competition was available.

ADT was forced to adopt a national price list, which could not be varied, to help establish Central Station Competitors in cities that had none and to pay fines and triple damages to the Federal Government, National Customers, and local Competitors.


In the late 1980s, ADT shareholders agreed to change the corporate name from American District Telegraph to simply ADT, Inc. By the mid 1990s, ADT surpassed the 1 million customer milestone. In 1991, ADT Canada launched the DVERS (Domestic Violence Emergency Response System) Program. In 1992, ADT launched the AWARE (Abused Women's Active Response Emergency) Program to help victims of domestic violence. ADT UK bought "Modern Alarms LTD" in 1996.


ADT was purchased by Tyco. This was, in fact, a reverse takeover of Tyco by ADT, thus allowing the Bermuda tax status.


ADT currently has branches in 50 different countries, with over 58 000 employees.

Tyco is the parent company of ADT. []

ADT had gross revenue of US $29.00 billion in 2007.
