What factor can cause a splice to oxidize and create false alarms if not done correctly?

• A. Splices Not Properly Soldered Or Not Crimped With Corrosion-Preventative Connectors Filled With Silicone Gel.
• B. Using Excess Heat During Splicing.
• C. Using Too Thick Insulation.
• D. Splices Have No Impact On Alarm Performance.

Answer: (A)

Oxidation at a splice happens when metal is left exposed to air and moisture. If a splice isn’t properly soldered or crimped with corrosion-preventative connectors filled with silicone gel, moisture can penetrate the joint and cause corrosion on the conductor. This corrosion increases resistance or creates an intermittent contact, which in a monitored alarm circuit can register as a fault or unusual condition, producing false alarms. Using proper soldering or a corrosion-resistant crimp connector with gel seals the joint from moisture, keeps the electrical path stable, and prevents the oxidation that leads to false indications. Excess heat, overly thick insulation, or the belief that splices don’t affect performance don’t address this moisture-driven oxidation and therefore aren’t the cause of the issue described.
