Mode 3 Socket |
||||||||
A Mode 3 socket is used to connect an alarm system or a personal medical device to the phone line for monitoring purposes. Most alarm systems can be programmed through the keypad to call,
Installing a Mode 3 socket must be done before the first phone socket on the premises. The correct wiring method of a Mode 3 socket, ensures that the alarm system has priority over the phone line and is able to dial out in the case of an emergency. This is regardless whether the phone line is in use, left off the hook or if a phone has been ripped out of the socket by an intruder. Mode 3 and ADSL BroadbandIf the alarm system is sharing the same phone line as an ADSL / Broadband service, then it must be filtered with a good quality Central Filter of Network Termination Device. Failure to do so will result in internet drop outs, slow speeds and even faulty operation of the alarm system. This type of installation should only be done by an experienced telecommunications technician who is able to re-configure the wiring to ensure simultaneous trouble free operation of the broadband, alarm and phones.

The newer Mode 3 sockets are partly blue in colour to help distinguish them from ordinary phone sockets. Common mistakes with installing a Mode 3 socket
