What is a reliable method to splice alarm wire?

• A. Twist, Solder And Tape.
• B. Twist And Tape Only.
• C. Solder Only.
• D. Crimp With Bare Connectors.

Answer: (A)

A reliable splice must provide both a solid electrical connection and proper insulation. Twisting the wires helps align them, but it can loosen over time. Soldering creates a permanent, low-resistance electrical joint, and then taping seals and protects the connection from moisture, corrosion, and movement. This combination—twist for alignment, solder for a strong electrical bond, and tape for insulation and protection—offers the most durable, dependable splice. Twisting alone lacks a durable electrical join; twisting with tape only leaves exposed conductors vulnerable; soldering only lacks mechanical stability; crimping with bare connectors provides no insulation and can lead to shorts.
