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.
