transistor, the function of which can be set from the keyboard, see the Alarms section of this manual.
The maximum operating voltage that can be applied across the terminals is 20VDC and the
maximum sink current for the switch 'closure' is 1mA.
Do not apply external voltages between the terminals exceeding 30VDC.
