Relay Output
Relay output is provided for connecting alarm devices or for remote on/off control of devices such as light.
Relay is normal open and it will be closed upon alarm annunciation or remote on. The relay is capable
of switching
30V AC/DC, 2A
. For the application which needs power switching beyond this limit, use
additional relay switch as shown in the right of Figure 2-5.
* Left : switching requirement below 30V, 2A
* Right : switching requirement higher than 30V, 2A. Apply this connection when either voltage or
current exceed the limit.
Figure 2-5. RELAY Output connection
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.
