Connecting the Alarm Input/Output Cable

Alarm Input

Connect the cable to sensors such as infrared sensors, door sensors, metal sensors and manual switches.

Input Requirements

● Non-voltage relay NPN open collector input

● Polarity of input detection can be selected

using a software

● Make/break (500 ms and above)

● Circuit current of 1 mA during low-level input

● Applied voltage of 3.3 V during high-level

Alarm output

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

Output Requirements

●NPN open collector output equivalent (Refer to the INSTRUCTIONS (Setting) on procedures to set the output logic. )

●Allowable applied voltage: DC 12 V and below

●Allowable inflow current: 50 mA

●Momentary (100 ms to 5000 ms) output (Refer to [INSTRUCTIONS (Setting)] for procedures to set the time. )
