Unlike other types of linear heat detectors, the MSL000 Digital Linear Heat Detector provides a very-early alarm detecting function for the protected environment. The detector is also known as an intelligent “switch” type detector. The polymers between the two conductors will break down at a specific fixed temperature allowing the conductors to make contact creating a short circuit, which in turn initiates the alarm. The detector has a continuous sensitivity which means that changes in environmental temperature won’t influence the linear heat detector. The system does not need to be adjusted or compensated for the length of detection cable in use. The detector can transfer both alarm and fault signals to control panels normally with or without DC24V.
Dual Temperature Linear heat detection cable is a type with higher-performance of dual temperature alarms. It is called “Dual Temperature Alarm” due to the fact that it allows for a double-knock alarm temperature system to be implemented. Level I is pre-alarm (lower rated temperature), Level II is confirmed fire alarm (higher rated temperature).
Dual Temperature Linear heat detection cable is comprised of three steel conductors each individually insulated with a unique heat sensitive polymer. The insulated conductors are twisted together to impose a spring pressure between them, then wrapped with a protective tape and furnish with an outer jacket.
