Applied to EN standard, serial connection to the loop. When a short circuit occurs in the loop, the isolation modules at both ends of the short circuit point act to isolate the short circuit.
JBE-2150 is an isolator module designed to operate on a loop of intelligent fire detection and alarm devices with the Jade Bird Europe loop protocol.
The isolator is placed at intervals on the loop and ensures that, in case of a short circuit, only the section between the isolators will be affected. The two wires of the loop section between the 2 isolators that are closest to the short circuit are disconnected, allowing to the rest of the loop to continue working. When the short circuit is removed, the isolators automatically connect the isolated loop section restoring power and data.
The total number of devices protected by each isolator should not exceed 32.
Convenient LEDs provide local information of the isolator status to support installation inspection and troubleshooting. The top LED turns ON when side A of the loop is disconnected, and the bottom LED turns on when side B of the loop has a short circuit.
