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
AC/DC,
2A. For the application which needs power switching beyond this limit, use additional relay switch as
shown in the right of Figure.
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.
