of switching 30V AC/DC,
additional relay switch as shown in the right of Figure 2-5.
Relay
* Left : switching requirement below 30V, 2A
* Right : switching requirement higher than 30V, 2A. Apply this connection when either voltage or
current exceed the limit.
 Sensor Input
Connect external alarm sensor. Examples of sensing devices are infrared sensor, motion sensor,
heat/smoke sensor, magnetic sensor, etc. Connect the two wires of the sensors to "SNS In". The sensor
type(NC/NO) can be set in admin page. Multiple sensor devices can be connected in parallel.
