- Controls up to 12 different floors
- Secure communication: RS-485 connection termination resistance
- Control an elevator with a maximum of 192 floors
- Fire alarm zone and anti-passback zone
Controls access to 12 different floors
Controls up to 12 output relays via RS-485 port.
Secure communication: RS-485 connection termination resistance
A maximum of 31 OM-120 modules can be connected to a master device via RS485 daisy chain, thus providing greater security in communication with the readers.
Control an elevator with a maximum of 192 floors
The OM-120 module can be configured for door control using BioStar2 software. The OM-120 can control up to 192 floors per elevator, and BioStar2 can control up to 1,000 elevators.

Fire alarm zone and anti-passback zone
With the Suprema OM-120 module, in addition to the anti-passback zone option, elevator groups can be added to a specific fire alarm zone, which can be configured via auxiliary ports and a relay. It also produces various output signals, including relay signals for inputs and different zones. The Suprema OM-120 module is compatible with the following Suprema access control terminals: BioStation 2, Xpass, Xpass S2, Secure I/O 2, BioStation A2, BioStation L2, and BioEntry W2.
