Sismik NOFIRE Electromechanical Earthquake Sensor
Sismik NOFIRE Earthquake Sensor activates emergency scenarios and enables controlled operation of critical building systems during seismic events. It is designed for public and residential buildings such as hospitals, schools, factories, and similar facilities where rapid response and safe automation are essential.
The device can stop elevators and bring them to the nearest floor, and it can also be used with power generators, solenoid valves, and power supply systems. With NO/NC dry contact outputs, Sismik NOFIRE can interface with building automation, safety systems, and shut-off mechanisms (e.g., gas shut-off and power cut-off).
Sismik NOFIRE provides both audible and visual indication through an inbuilt sounder and an LCD display. Battery backup and fault monitoring functions support continuity and clear status feedback for installers and end users.
Key Features
- Electromechanical seismic sensor for emergency scenario activation
