Can directly sense temperature and emit signals through physical operation without the need for a power source or measuring equipment. 2. When the surrounding temperature reaches the set temperature (80°C), the two wires short-circuit to sense the temperature and generate a signal. 3. Can be wired similarly to electrical wiring. It can be used for both indoor and outdoor wiring. 4. The shape memory alloy has permanent memory, is rust-free, and retains its state once activated, allowing for long-term use. 5. This product meets the performance standards of fixed temperature type detectors as specified by fire safety regulations (120 seconds). 6. Non-resettable, allowing for confirmation after activation. (Once activated, it cannot be reactivated. The activated location can be deleted and reconnected.)
