Shielded alarm cable

Wire strippers

Crimping tool

RJ45 connectors


Electrical tape

Cable tester

Safety glasses

Step-by-Step Instructions

Here are the step-by-step instructions for installing and testing shielded alarm cables:

1. Prepare the Cable

– Cut the shielded alarm cable to the desired length.

– Strip the outer jacket off the cable, exposing the four conductors.

– Twist the conductors together to form a solid connection.

2. Crimp the Connectors

– Crimp an RJ45 connector onto each end of the cable.

– Make sure that the connectors are crimped securely.
