On detection of a temperature above the user defined maximum, the OTMA will immediately go into alarm. When this happens an audible alarm is sounded and a red LED illuminates, at the same time the two volt free changeover relays switch. One relay can be connected to an autodialler that will call a set of predefined telephone numbers, the other can be connected to the BMS.
- Typical applications include computer rooms, comms rooms, server rooms, data centres an plant rooms where excess temperature will adversely affect the performance of the equipment housed in it.
The OTMA can be connected to a tamper proof temperature sensor or a digital display temperature sensor.
