    摘要: A manual call point for a fire alarm system, the manual call point includes: an operating element 18, wherein a physical movement of the operating element 18 will trigger an alarm condition of the manual call point; at least two switch devices 12, 14, 16. Each switch device 12, 14, 16 is arranged to complete or break a circuit in response to the physical movement of the operating element 18. At least one of the switch devices 12, 14, 16 is a contactless device 12, 14 and the corresponding circuit includes an electromagnetic circuit that is completed or broken without mechanical contact from the operating element 18.

    摘要: Some embodiments are directed to a lockdown apparatus for facilitating initiation of lockdown procedures at a facility. The lockdown apparatus can include a manually operated actuator disposed at the facility and configured to transmit a lockdown initiation signal upon being manually actuated. The actuator can be configured to be recognizably distinguishable from a fire alarm actuator. The lockdown apparatus can also include a lockdown communicator configured to produce a lockdown communication for communicating initiation of lockdown procedures to the facility occupants and individuals not disposed proximate the facility upon transmission of the lockdown initiation signal, the lockdown communication being recognizably distinguishable from the fire alarm communication. The lockdown communicator can include an annunciator that communicates an audible annunciation to facility occupants upon transmission of the lockdown initiation signal, and that ceases to communicate the audible annunciation subsequent to a predetermined number of alarm cycles.
