Which statement about 22/4 stranded wire is true?

• A. It is used for many alarm peripherals
• B. It is used for data transmission only
• C. It is used for HVAC connections
• D. It is used for power supply to lighting

Answer: (A)

In alarm wiring, 22/4 stranded cable is a small, flexible multi-conductor option that fits many low-voltage devices. The four conductors let you carry power and signaling to multiple peripherals in one run, or run two separate circuits, which is why this type of cable is commonly used to connect alarm peripherals like door/window contacts, motion sensors, keypads, and sirens. It’s not limited to data transmission, and alarm systems don’t rely on this cable for data networks. HVAC wiring and lighting power typically use different gauges and wiring standards, so they aren’t the typical uses for 22/4 stranded cable.
