BW-1 Line Seizure Connector For Use In Standard Telephone Company Enclosure
Above we see a Standard Telephone Line Interface showing several sets of wires providing dial tone to various parts of a home or business.
For this illustration, there is only one active phone number, but sometimes there will be several. Normally the alarm installer would be removing all of the wires from the screw terminals and connecting a new 4 conductor wire that goes to the alarm panel. Typically the alarm installer will use a pair (normally red and green) to connect to the screws, and the other pair (normally black and yellow) connected to the loose wires and finish the connection with chicklets, wire nuts or tape. This is the old method of wiring for line seizure to the alarm panel. The biggest problem with this is that the phone company does not recognize this as a standard type of connection and any time they come out for service, they will take your work all apart and probably put everythnig back in parallel on the screw terminals, defeating your line seizure.
Sometimes, not understanding the use of the black, yellow, red, and green on one number, they will just leave your wire disconnected.
Here we see the BW-1 Connector installed. As you can see, the BW-1 male connector is inserted into the female jack of the interface. The dial tone is now diverted through the BW-1 into your alarm panel. and the returning dial tone from the alarm panel is reconnected to the interface through the female side of the BW-1. Simply insert the male jumper wire from the interface into the female port on the BW-1 and you have completed you connection with the following advantages:
1. You saved time
2. You have provided a permanent line seizure connection, no matter what changes or additions occur to the wires on the screw terminals after your alarm connection is made.
3. You have provided the Telephone Company and the Home or Business owner a quick and simple way to completely remove the alarm system from the phone line in seconds. This is very convenient to both you, and your customer should the need arise for testing or servicing of the line.
Here you can see that there is plenty of room to tuck in the BW Connector and have plenty of clearance to close and secure the Interface enclosure. We have done extensive field testing and done actual installations of the BW-1 and BW-2 Connectors in Interface enclosures that have up to 6 phone lines installed with lots of additional wiring.
Now that your phone line connection has been made, close the box, and you're done!
