How Alarm_Input and Alarm_Output Work
“Alarm_In” is the alarm input port. Users are able to connect 3
r d
p a r t y sensors such as infrared
sensor, smoke sensor or light sensor to it.
The detectable signal voltage range for “Alarm-In” is from 1.8V to 15 V
“Alarm-Out” uses relays as a switch (30VAC/2A). Users can connect 3
rd
party devices such as
alarm siren or alert light to this port. Under normal circumstances, the circuit is open. When there
is an alarm event, the GXV3601_HD will close the circuit to trigger the alarm.
NOTE:
Please do NOT connect a device that has a signal voltage higher than 15V, this will damage
the GXV3601_HD.
