THE POwER SUPPLy
Ingressus must be powered up by 12VDC 3A independently. DO NOT share
the power supply with any other devices, slave terminals or door lock sys-
tems.
Sharing power supplies might cause insufficient power to Ingressus.
The Ingressus DOES NOT support POE. Link up your Ingressus with backup
power supply, for example UPS or rechargeable backup battery, to keep
the system working even during power failure.
Ingressus can work as an intermediary to supply power to a door lock sys-
tem. You must supply additional power to Ingressus at the LOCK V+ and
V- ports. The input power is for supplying power to the door lock system.
Check the technical specifications of your door lock system, for example
12VDC, 500mA. Calculate the total current consumption before you deter-
mine the power supply to LOCK V+ and V-. For example: 4 sets of 12VDC,
500mA door lock to install with Ingressus.
Total current consumption = 4 x 500mA = 2000mA (2A)
You must supply at least 12VDC 2A power into the LOCK V+ and V- ports
of Ingressus.
The maximum input is 12VDC 3A, and limited to DC power only.
You can ignore the LOCK V+ and V- ports if you are installing door system
with individual power supply. Ingressus does not power up the door lock
system in this situation, but only outputs relay signals to control the door
lock system.
THE DOOR LOCk SySTEM
There are 2 methods to link up Ingressus with door lock system, either pow-
er output (wet-contact) or relay output (dry contact).
To use wet contact, you must provide additional power supply to Ingressus
with specifications suitable for the door lock system. This is very crucial to
ensure sufficient current to be supplied to the door lock system. Ingressus
receives the input power and supplies it to the door lock system. During
operation, Ingressus will control the power output to the door lock system
to unlock/lock the door. You can input a maximum of 12VDC 3A to Ingres-
sus to support up to 4 sets of door lock systems.
