Linear Heat Sensor cable is a flexible, durable and cost-effective fixed temperature fire detector, suitable for protecting a wide range of commercial and industrial fire applications where spot-type heat detectors are unsuitable. Simple and easy-to-install, the LHS cable connects directly to
the fire alarm panel initiating circuit. A short circuit along the LHS cable indicates a zone alarm
condition. The LHS cable is available in a variety of operating temperatures and jackets.
The heat from a fire causes the LHS cable’s special insulation to melt at a specific temperature, allowing the two conductors to short together, thus creating an alarm condition on the fire control panel.
