Questions :  How to configure a 12V external alarm to AR-721-H?

Problem Solving :

Card reader on the left, a 2p relay on the right is displayed as pictured. If you would like to synchronise the alarm working the same time when flashing a valid card on reader, please connect blue/white cable of reader to relay’s CTL. If you want the alarm also working when flashing an invalid card and at the same time the external alarm works when any warning occurs, please connect grey cable of reader to relay’s CTL instead.
