It can be installed in the entrance guard or security equipment such as doors, windows, drawers
and safe case..
Source mode (Voltage input) :
IN1-IN4 contacts are active signal sensor. If the voltage difference between the two contacts in
one set within 0V~3V, 9212 shows ON. It the voltage difference within 4V~24V, 9212 shows
OFF. So user can detect the change of equipment. Such as smoke detector, light detector and
gas detector.
NOTE:
1. The data in this figure is the average
measure value. To ensure the correct
detection, we suggest user set the voltage
lower than 3V when it shows OFF and higher
than 4V when it shows ON
2. The maximum measure voltage is 24V.
.
Slink mode (Resistance Input ) :
IN5-IN8 contacts are short circuit sensors. If the resistance between the two contacts in one set
within
0Ω~200Ω, 9212 shows ON. If the resistance within 500Ω~ ∞,
9212 shows OFF. So the
users can detect the movement of equipment through the magnetic reed switch or other kind of
reactive sensors.
NOTE:
1. The data in this figure is the average
measure value. To ensure the correct
detection, we suggest the user set the voltage
