N502 Door Module Connections

The Door Module connections are:

• RS-485 IN — Main bus input terminal. The main bus connection to the Door Module comes from the main bus output of other bus devices or from the Net Bridge. The main bus consists of a data bus and a power supply.

• RS-485 OUT — Main bus output terminal. Use the main bus output terminal to extend the bus to the next bus device.

• CYLINDERS — You can connect two lock cylinders to this terminal, allowing you to remotely control the lock cylinders. The lock cylinders must be in the same door or in neighbouring doors with the same ground potential. In other words, the cabling distance of the lock cylinders from the Door Module must be 10 m or less. If the distance is longer, use two Door Modules, one for each cylinder.

• INPUTS - IN 1/IN 2/IN 3 — These potential-free inputs can be set to control relay outputs K1 and K2 or used to generate door status information in the Monitored Doors view of iLOQ 5 Series Manager.

• INPUTS - EXT + COM — Potential-free outputs connected to these inputs can be set to control a restricted access right when the Door Module is programmed as a lock.

• READER RS-485 — The reader bus is separate from the main bus. It is for the RFID reader. A reader connected to the reader bus controls relay outputs K1 and K2 according to the selected operating mode.

• RELAY K1/K2 — Relay outputs K1 and K2 can be used to control an external device such as an electronic lock. You can control the relay outputs according to the selected operating mode, either by using a lock cylinder, a key or RFID reader, a code, a calendar control, or an external device such as a door opening button connected to inputs IN1 and IN2.
