ABSTRACT:
An arrangement for testing an alarm system, requiring only a single individual. The alarm system itself includes an alarm activation circuit, a main alarm, for example an audio alarm, and a plurality of remote sensors all connected together such that activation of at least one of the remote sensors activates the alarm circuit which, in turn, activates the alarm. The testing arrangement senses whether the alarm activation circuit has been activated in response to the activation of one of the sensors. If it has, the testing arrangement automatically deactivates the alarm circuit and the alarm, preferably in an adjustably fixed period of time after activation of the circuit. Thereafter, preferably after a second adjustably fixed period of time, the arrangement automatically causes the alarm activation circuit to be reset. In addition, the testing arrangement preferably includes its own alarm preferably an audio alarm, which is activated during this second adjustably fixed period of time. At the end of this period the second alarm is automatically deactivated.
