In any plant, when a process parameter goes to abnormal limit, the operator has to be alerted immediately, so that he can take corrective action to bring the parameter back to normal. And also when the parameter returns to normal, the operator should be alerted immediately. This task of bringing the attention in such conditions is accomplished by alarm annunciation system. Our annunciator is a microcontroller based system and has the operating sequences reset, test, mute, and ack as input and individual output indication for each channel for status indication. It is available in three models as table, panel mounting & wall mounting with window indicator & led version. This annunciator has the facility to interact with computer for data logging and data retrieval and data analysis through visual basic available on request
