AXIS A1601 Network Door Controller
Specifications
Relay connector
Two 4-pin terminal blocks for form C relays that can be used, for example, to control a lock or an interface to a gate.
Function
DC ground (GND)
NO
COM
NC
Relay power jumper
When the relay power jumper is fitted, it connects 12 V DC or 24 V DC to the relay COM pin.
It can be used to connect a lock between the GND and NO pins.
Power source
DC IN
PoE
1. The power is shared between the two relays and AUX I/O 12 V DC.
NOTICE TICE
NO NO TICE
If the lock is non-polarized, we recommend you to add an external flyback diode.
Auxiliary connector
Use the auxiliary connector with external devices in combination with, for example, motion detection, event triggering, and alarm
notifications. In addition to the 0 V DC reference point and power (DC output), the auxiliary connector provides the interface to:
Digital input - For connecting devices that can toggle between an open and closed circuit, for example PIR sensors, door/window
contacts, and glass break detectors.
Digital output - For connecting external devices such as relays and LEDs. Connected devices can be activated by the VAPIX®
Application Programming Interface or from the product's webpage.
6–pin terminal block
Pin Notes
1
2 Normally open.
For connecting relay devices. Connect a fail-secure
lock between NO and DC ground.
The two relay pins are galvanically separated from the
rest of the circuitry if the jumpers are not used.
3
Common
4
Normally closed.
For connecting relay devices. Connect a fail-safe lock
between NC and DC ground.
The two relay pins are galvanically separated from the
rest of the circuitry if the jumpers are not used.
