Abstract

An electro-mechanical ventilator control mechanism comprises a rotary actuator (19) operable to move a control arm (1) to open and close the ventilator via a force transmitting member (10) formed in two sections (4, 5), normally retained telescoped one within the other by an electromagnetic device (2, 3) mounted on the section (4) and an electromagnetic keeper plate (4) mounted on the section (5), spring means (7) being provided pulling on the end of the member (10) and tending to open the ventilator. De-energisation of the electromagnetic device (2, 3) e.g. under the control of an automatic fire ventilating system, releases the keeper plate (4) and allows the ventilator to open under the action of the spring (7). Subsequent operation of the rotaray actuator (19) and re-energisation of the electromagnetic device (2, 3) re-sets the ventilator for automatic operation. Instead of a rotary actuator (19) a linear actuator (20) may be used.
