Abstract
An automated testing apparatus for remotely performing a testing sequence to ensure that a sensor is functioning. The apparatus can include a detector, a storage container, a burst valve in fluid communication with the storage container, a testing control module in communication with the storage container and the burst valve, and a remote user interface remotely located from the detector. Preferably, the automated testing apparatus can simplify the testing procedure, increase the frequency of sensor testings, thereby notifying operations of sensor failures in a more timely fashion without the need for an operator to check the sensor locally.
