Abstract: The present apparatus concerns round monitoring and includes a portable recording device together with a plurality of keys for indicating different locations through which a watchman is to pass. In order to simplify the drive mechanism of the apparatus, the apparatus comprises a clock movement (20) having an hours shaft on which a disk (34) is mounted having time data print elements (36) disposed around its rear face. A strip of paper (50) is displaced between said print elements (34) and a print hammer (52).

Abstract: A plurality of watch stations are installed in protected premises that must be tripped in proper sequence once each hour and embodies means whereby when the watchman comes on duty and starts his rounds of duty, a signal will be transmitted to the central station and when he has completed the rounds of stations a second signal will be transmitted to the central station indicating that all is well. In the event the proper sequence of operation of the watchman's stations is broken, an alarm will be indicated in the central station. Thus the central station receives only two signals regardless of the number of stations on the watchman's route unless there is something wrong with the watchman and he is in need of help. The present system is designed to prevent tampering with the system, to prevent the system being turned off prior to the end of the watchman's tour of duty, and to permit the watchman to signal for outside help from anyone of the stations on his tour.
