Note:
It is highly recommended that you connect the fire alarm button to the 12V power
port and electromagnetic lock directly, as the figure below shows. This enables all the
associated doors to be triggered even if your GV-AS41 / 81 series Controller behaves
abnormally when a fire condition occurs.
