Abstract

A call point for use in fire or intruder alarm systems, said call point comprising a displaceable or frangible element 4;40, at least a portion of which is manually displaceable in order to actuate a switch 8 to indicate an alarm condition, the element 4;40 being displaceable between a first position and a second position, the switch 8 being actuated when the element 4;40 moves from its first position to its second position, a spring 9 biasing the element from its first to its second position, the call point further comprising a latch 11 having an abutment 12 engageable against the element 4;40 to maintain the element 4;40 in its first position against the action of the spring 9, the latch 12 being rotatable by a key 6 from an active position wherein the abutment 12 engages the element 4;40 to an inactive position wherein the element 4;40 is free to move to its second position under the action of the spring 9, in order to actuate the switch 8 and thus test the alarm system.
