Operation
The probe of the Alarm is positioned at the desired location e.g. back of the Server, A/C duct, Panel outlet etc. The user sets the desired cut-off limit by using the SET switch on the Temperature alarm.
Once the temperature rises above the cut-off limit the alarm goes-off continuously. Simultaneously the Voltage free NO/NC contacts also get activated. The NO/NC contacts can be used for connecting to NMS or any other system. The user can acknowledge the alarm(switch off the alarm) by pressing the reset switch. This implies that user has taken note of the situation and shall deal with it and there is no longer need of an alarm.
The user at this stage may switch on the additional fans etc. and bring down the temperature to the desired limits. Once the temperature goes down below the Cut-off limit, the alarm is automatically armed AGAIN. If the temperature goes up again beyond the cut-off limit then the alarm shall sound automatically, as before. This is a unique feature, specially designed keeping in mind this application.
Optionally, the alarm can be used to automatically switch on fans etc., or to convey message to the desired people using regular telephone lines. This requires additional customization.
