Under NBFAA standards, how should splices be prepared?

Explanation:
Splices must be made to provide a solid electrical bond and proper insulation. The correct method is to twist the conductors, then heat-solder them to form a secure, low-resistance connection, and finish by insulating with listed electrical tape or by securing with listed solderless crimp connectors. Using listed components ensures the splice is designed and tested for alarm work, giving reliable performance and protection against shorts, corrosion, and mechanical movement. Twisting alone or adding only non-listed protection leaves the splice vulnerable, and relying on crimp connectors without the soldered bond or twisting can reduce reliability in fire alarm circuits.
