Free Fall Fire Valve Accessories

Solenoid Quick Release Mechanism
The Solenoid Quick Release Mechanism MKI 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.

The MKII unit is as above but incorporates two switched power outputs, one normally on and turns off, the other is normally off and turns on in the event of an emergency.

Electro Thermal Links
The electro thermal link is installed above any potential fire risk so that the thermal fuse melts in the event of a fire and will cut the electrical supply.
Technical Specification
Electrical rating - up to 250v 50Hz, 5A.
Thermal fuse - 73°C(163.4°F) standard.
Optional fuses (to special order)

Valve Mounted Mercury Switches
The Landon Kingsway mercury switches are designed to be used in conjunction with our Free-Fall Fire Valves to provide position sensing or to cut power to oil burner pump motors in the event of a fire.

The unit is available in both a single and three-phase style although the three connections on the threephase version could be used to control three singlephase devices. Both versions contain contacts that remain closed while the valve is in its’ normal state (one contact on the single phase, 3 on the 3-phase) and a separate normally open contact that is suitable for sounding an alarm as it closes if the valve lever drops.

Fire Control Panel
The Fire Control Panel 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). In addition, a spare set of changeover volt free contacts is provided for connection to BMS or other.
