BUS short-circuit isolation module
This product is a part of the JABLOTRON JA-100 alarm system. It serves for better protection of bus cable lines indoors. It separates the outdoor part of the BUS line from the line inside the house. If the outdoor section is damaged (e.g. an intruder short-circuits the cable), the branch line of the system inside remains functional.
The use of the isolator is mainly recommended in cases, where the bus cable is routed outside the room to be monitored. Using the isolator, separate floors (or wings) in the house can also be separated.
The isolator can also be used to extend the cable, in the case of a long line, signal transmission is improved. The module is intended to be installed by a trained technician with valid Jablotron certificate.
Installation
The module can be installed in a JA-190PL (Jablotron) mounting box, in the control unit cabinet and/or in a standard el. installation box. Always best inside the room to be monitored.
Any number of isolators can be installed in the system. However, it can only be used for the branches of the inner BUS line. No isolators may be connected one after the other.
Before connecting the BUS, the system must be disconnected from the power supply.

After connecting cables and switching on the system, the isolator is functional. It does not need to be arranged in the system (it does not occupy a position).
Function
The isolator interrupts the line from the output bus (O) for 5 sec in the following cases:
1. The current to be taken from the isolator exceeds 250mA (terminals +U and GND on the OUTSIDE side)
2. The voltage on the supply BUS drops below 9V (terminals +U and GND on the INSIDE side)
If the high decrease or the dropped voltage is permanent, the output bus (O) remains permanently interrupted, possibly the voltage can operate in cycles of 5 sec. When the output bus is interrupted, the yellow signal light (2) will be permanently lit.
When a wired peripheral is to be connected at a long distance and the signal quality improvement module is applied, care should be taken to ensure that there is sufficient voltage on the supply side of the bus (by using a properly sized cable), so that when the input voltage drops below 9 V, the output side (O) of the bus is not interrupted.
Picture: example of installation in a JA-190PL box.
