4.4.1 GAT NET.Lock 7020 Connection
CAUTION!
- Do not connect the GAT NET.Lock 7020 locks to the GAT SMART.Controller S 7000 as this controller only
operates with GAT SMART.Lock 7001 locks. The GAT NET.Controller S 7020 sub controller must be used to
connect the GAT NET.Lock 7020.
- It is possible to connect the previous GAT NET.Lock 7000 locks to the GAT NET.Controller S 7020 sub controller;
however, only when the controller is unpowered. If a GAT NET.Lock 7000 is connected to a powered GAT
NET.Controller S 7020 sub controller that has only GAT NET.Lock 7020 locks connected (24 V operation), the
GAT NET.Lock 7000 is destroyed as 24 V is too much. If a GAT NET.Lock 7000 is connected to an unpowered
controller and power is turned on, the GAT NET.Controller S 7020 detects the GAT NET.Lock 7000 and switches
the system to 5 V. Both the GAT NET.Lock 7000 and the GAT NET.Lock 7020 can operate together as normal
in this situation, but the USB and LED functions are disabled.
NOTE!
- It is possible to connect the GAT NET.Lock 7020 (USB) P (with 125 kHz reader) and the GAT NET.Lock 7020
(USB) (13.56 kHz reader only) together on the same controller.
Depending on the type of sub controller, up to 24 GAT NET.Lock 7020 can be connected per sub controller. The locks
are identified via the channel numbers indicated on the side panel of the sub controller. Therefore, it is important
where the locks are connected and how the locking system is configured.
► Locate the sub controllers in a position that allows the locks to connect using minimal cabling, e.g., directly on
top of or underneath the lockers.
► Connect the GAT NET.Lock Cable from the GAT NET.Lock 7020 locks to the 4-pin MOLEX connectors on the
side panel of the GAT NET.Controller S 7020.
