(shown on the Picture 3.5), the signal opening the door outputs to the lock controller via «1A» and
«1B» pins.
ATTENTION!
Switching off - switching on the door station with the 1-channel controller (NC101 or NC101P) causes an
uncontrolled door lock opening. It happens because of peculiarities of the auto testing procedure which is
performed by the door station when it is switched on. Provide uninterrupted power supply of the door
station and the lock to prevent a door opening.
In case of the 3-channel door station controller, NC301P2, the signal opening the door
outputs to the lock controller via «1A» and «1B»/«1С», «2A» and «2B»/«2С», «3A» and
«3B»/«3С» pins for the first, the second and the third channel accordingly (Pic. 3.6). The «A» and
«B» pins are normally open, and the «A» and «С» pins are normally closed.
The «G» and «12V» pins of the NC101 controller (without PoE support) are used for DC
12V power supplying of the door station. It is necessary to connect a power supply recommended
by Enviro Cams and the lock controller to these pins.
The «G» and «12V» pins of the NC101P / NC301P2 controller (with PoE support) are used
for powering the lock controller (several lock controllers) with DC 12V. In this case it is necessary
to connect only the lock controller to these pins.
ATTENTION!
Use only DC 12V power supplies recommended by Enviro Cams!
Power supplying using both PoE and the «G» and «12V» pins (for NC101P and NC301P2 controllers) at
one time is prohibited!
ATTENTION!
Maximum current rate provided by the NC101P, NC301P2 controllers for powering door locks and their
controllers is 500 mA. If this value will be exceeded the device may operate incorrect and be damaged.
The device breakdown caused by the exceeding of the maximum current rate is not covered by the
warranty.
