Ojmar OTS20 Advance – advanced electronic RFID locker lock

The Ojmar OTS20 Advance is an advanced electronic RFID locking system for secure and flexible operation of lockers and cabinets. It is designed for professional environments such as fitness and wellness centres, swimming pools, changing rooms, offices, schools and universities. The OTS20 replaces the traditional mechanical key and cylinder with an electronic system operated using an RFID credential.

Users can open and close their locker using a compatible RFID card, wristband, FOB, sticker, transponder or other compatible RFID credential. The OTS20 supports several MIFARE® technologies including DESFire EV1 and EV2, Ultralight, Ultralight C and Classic 1K/4K. This makes the system suitable for a wide range of access and locker management applications.

Flexible operating modes

One of the main advantages of the OTS20 Advance is its extensive configurability. The lock supports free, dedicated, multifunction and renting modes. In free mode, for example, one RFID credential can be used with up to three lockers simultaneously, while dedicated mode allows specific lockers to be assigned to users.

The OTS20 also offers a multifunction mode and a configurable renting mode with 15-minute periods. Automatic opening can also be configured, allowing the same locking system to be adapted to different users and locker applications.

Management with Ojmar software and NFC Programmer

For advanced management, the OTS20 can be combined with the optional Ojmar NFC Programmer and OTS Management Software. Locks can be configured and access permissions can be assigned using the software. The system can also store events, allowing information such as the lock used, action, user, key and date to be retrieved.

Communication with the lock is performed using NFC, while electronic communications are protected by AES-256 encryption. Firmware updates can also be carried out via NFC, and the lock configuration is retained when the batteries are replaced.

LED indication and emergency power

An integrated LED in the operating knob provides red, amber and green status indications. The system automatically detects a low battery level and provides a warning when battery replacement is required.

The OTS20 is powered by four AA alkaline batteries and, according to Ojmar, offers a battery life of up to 10 years at room temperature, depending on usage and configuration. If the batteries are completely discharged, the OTS20 also provides an emergency power supply through the operating knob.

Suitable for different locker doors

The Ojmar OTS20 Advance is suitable for phenolic, HPL, glass and melamine doors with a thickness of less than 20 mm. Installation on metal doors is also possible when the required booster is used.

The lock is available in both left- and right-handed versions. The grey RAL 7035 housing offers IP55 and IK09 protection. The electronic components, batteries and mechanical locking system are protected inside the lock.
