The ETI LOP system responds very quickly to fire detection when it is used in the risk area. It constantly supervises the actuation circuit. One feature of LOP system is that the actuation and detection system are constantly pressurised by the nitrogen charge in the cylinder which makes it supervised system. This type of detection systems is simple to route in the fire risk area due to the flexibility of the thermoplastic tube.

System arrangements:

1. Thermoplastic tube LOP sensor

2. Manifold

3. Switches

4. Manual actuators

5. Pressure vessel and the valve – LOP or Dual

6. Discharge piping and nozzles

7. Alarm panel
