Unshielded security alarm cable is a type of cable used in security alarm systems to connect sensors, detectors, and other components to the main control panel. Unlike shielded cables, which have a protective layer to reduce electromagnetic interference, unshielded cables do not have this additional layer.

Unshielded cables are generally less expensive and more flexible than shielded cables, making them a popular choice for residential and small commercial security alarm installations where the risk of interference is low. However, in environments with high levels of electromagnetic interference, such as near large motors or electrical equipment, shielded cables may be preferred to ensure reliable signal transmission.

When using unshielded security alarm cable, it’s important to follow the manufacturer’s recommendations for installation to minimize the risk of interference and ensure proper system operation.
