Mode 3 Socket
A Mode 3 socket is used to connect an alarm system to the phone line for monitoring purposes. Most alarm systems can be programmed through the keypad to call;
- A mobile phone
- A back to base company
Our technicians are constantly rectifying the wiring configuration on Mode 3 sockets that have not been installed correctly. Although this is not illegal, it is not best practice and is certainly not in the clients best interests.
Installing a Mode 3 socket must be done before the first phone socket on the premises.
The correct wiring method ensures that the alarm system has priority over the phone line and is able to dial out in the case of an emergency regardless if the phone line is in use, or if a phone has been ripped out of the socket by an intruder.
Mode 3 and ADSL Broadband
If 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. 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.
New and Old style Mode 3 Sockets
There are two different types of Mode 3 sockets being used in the Australian market. The older, more cumbersome style is referred to as a 611 socket.
The newer one is a RJ style socket that is partly blue in colour to help distinguish it from ordinary phone sockets.
