Alarm input signal

Connects to sensors such as infrared sensors, door sensors, metal sensors and manual switches.

To prevent noise from entering the internal circuit, supply non-voltage contact signal to the alarm input signal.

Do not supply voltage.

When the contact is short (MAKE) or open (BREAK) on the menu, you can set it to Alarm.

Supply such that the alarm signal continues for at least more than 500 ms. The alarm signal may not be recognized if it is less than 500 ms.

Alarm output signal

Connect to alarm devices such as alarm, indicator, light or buzzer.

Alarm output signal is an open collector output insulated with photo coupler.

During an alarm, it is ON.

As this terminal is polarized, be sure to connect it such that the voltage of the + output is higher than that of the - output.

It will be damaged if reverse voltage is supplied.
