Check if your output device meets the following absolute maximum ratings before
connecting it to the Door outputs.
Breakdown Voltage
250V AC, 220V DC
Continuous Load Current
1A (30V DC), 0.3A (125V AC)
Note: Absolute Maximum Ratings are those values beyond which damage to GV-
AS120 circuit board may occur. Continuous operation of GV-AS120 at the absolute
rating level may affect GV-AS120’s reliability.
To connect an output device:
The example below illustrates the connection of a locking device to GV-AS120. Connect the
(+) point on the locking device to the Door COM wire on GV-AS120, connect the two (-)
points of the locking device and the external power supply together, and connect the (+)
point on the external power supply to the Door NO or Door NC wire on GV-AS120 based on
the state of the locking device.
