DescriptionElectromagnetic Quick Release For Drop Weight Fire valves (E-MAG & E-MAG 2)The E-Mag and E-Mag2 Electromagnetic quick release mechanisms are for use with electrically actuated fire valve systems. They provide instant release of Free Fall Fire Valves when de-energised, making them the ideal method for remote fire valve closure.The E-Mag is a standard electromagnet, which will de-magnetise on loss of power, the EMag2 version has inbuilt auxiliary volt free changeover contacts, which signal valve status.Both E-Mag and E-Mag2 may be installed as ‘wall mounted’ or ‘direct mounted’.Wall mounted E-Mag or E-Mag2 installations can can be designed to release a stainless steel fire valve cable, which can be used in the normal way with pulley wheels and fusible link, by using an interface which will isolate a fuel supply in the event of a Fire Alarm or other means of control input by de-energising the electromagnet. Similar to the way in which an automatic fire door closes in the event of a building fire alarm. However, the system still incorporates a fusible link, providing a mechanical means of fire valve shut off as well as electrical control.Direct mounting installations have the E-Mag or E-Mag2 sited directly above the fire valve and do not incorporate a fusible link in the system, but rely upon electrical control only.Both E-Mag & E-Mag2 version include a ‘Push to test’ facility and have 40Kg electromagnetic holding power as standard.As well as the Electromagnetic Quick Release For Drop Weight Fire valves we also offer other accessories for drop weight fire valves such as the mercury switch, manual quick release and complete fitting kits and spares, as well as the valves themselves.
