Abstract (en)

A re-settable alarm call point 1 has a lever 22 biased to a non-activating position by an over-centre spring 23. The lever 22 is movable against the biasing of the spring 23 towards an activating position by manual depression of a pressure plate 10 and, when the spring 23 passes through an intermediate unstable position, the lever 22 is biased to the activating position to trigger the call point. An indicator panel 15 is concealed in the non-activating position of the lever 22 and is released in response to displacement of the lever 22 to the activating position to provide a visual indication of the actuation of the call point 1. The call point 1 is manually re-set by inserting a key in the end of a cylinder 33 to return the indicator panel 15 to the concealed position and rotate the cylinder 33 to actuate a cam 38 to return the lever 22 to the non-activating position. <IMAGE>
