Use of a Telephone Line

Do I Really Need One?

1  Why do I need a telephone line for monitoring of my system? The signal between your monitored home security system and the ADT Alarm Receiving Centre is passed through a telephone line so you will need active line to enable this transaction.

2  Will the alarm system work on telephone lines not provided by British Telecom? This depends on which type of monitoring you require. However our system is compatible with most current telephone suppliers.

3  What if there is a fault with my telephone line? In some instances the system will emit an audible tone if the telephone line has a fault at any time other than during an alarm. For further peace of mind we can advise on how your telephone line can be made more secure, using alternative technology.

4  Will the equipment I currently have on my telephone line such as a fax, answering machine, or personal computer affect my security system? Our security advisors will be happy to provide you with advice on this subject. In most instances there will be no problems; however in certain instances it is advisable to have a separate dedicated telephone line for your security system.
