Fire protection system.

Description

Fire protection system comprising:


- Free-fall Fire Valves:

These provide a compact, leak-proof positive action mechanism that can be installed in either horizontal or vertical pipe runs on oil or any non-aggressive media. The valve may be used for either cut-off or dump applications. The free-fall linkage allows the weight to start to fall before it is required to move the valve lever. This makes sure that the weight achieves sufficient momentum.


- Solenoid Quick Release Mechanism:

This is designed to provide a simple electro-mechanical release mechanism for gravity-operated devices such as the Landon Kingsway free-fall fire valve. The system consists of a steel cable wound around a drum with a solenoid arranged so that when energised, the drum is locked in place. If the electrical supply to the solenoid is interrupted then the solenoid latch releases the drum and the weight of the attached load causes the cable to unwind.


- Fire Control Panel:

The is used as the main control unit for a fire protection system. It can be connected to various sensors such as panic buttons, electro-thermal links and gas detectors using a simple loop wiring system. The panel provides a normally on power outlet to control fire valves, boilers and a normally off power supply to the alarm(s).


- Electro-thermal Link:

This is installed above any potential fire risk so that the thermal fuse melts in the event of a fire starting. The link is connected in a normally closed electrical circuit so that if it melts an alarm is generated.
