JB 370-5 is a junction box which simplifies the installation of the GD 370 glass break detector. The junction box connects max 5 GD 370 with IU 370 and/or multiple JB 370/JB 370-2/JB 370-5.

JB 370-5 is equipped with a built-in resistor for termination of glass break (optional with jumper) as well as a jumper which allows for use of GD 370 with relay towards IU 370. It also has tamper protection.

When installing multiple GD 370 in a location which allows for a common junction point JB 370-5 is an excellent choice of junction box.
