SENSOR INPUT :Connect two signal lines of sensor (infrared rays sensor, heat perception

sensor, magnetic sensor) to the desired sensor number.(You can set the type-NC or NO- of

sensor at “Setup” mode).

ALARM OUTPUT : Use this at 30V/300mA or less operating voltage and current. When

controlling lamp and AC operated equipment, control it using separate outside relay. During

normal operation the control output contact is maintained at “Open” status, and during control

output the output contact is changed to “Close(short)” status.

SENSOR inputs need dried contact only. Do not input any electric signal.
