Wireless connectivity module Ajax ocBridge Plus model 000001152 for integrating Ajax devices with IP-based systems

Ajax ocBridge Plus (model 000001152) is a wireless connectivity module that converts wired and IP-based security systems into a hybrid solution by bridging Ajax radio devices with Ethernet/IP networks. The module enables remote monitoring, alarm forwarding and system integration for professional security installations and smart home setups while supporting a large radio network and protection measures against interference and tampering.

Advantages

Jeweller radio technology enables reliable communication with Ajax devices at distances up to 2,000 m in open space and across multiple floors, while antenna diversity and frequency hopping reduce the risk of radio interference and jamming. The module supports up to 100 connected devices, 8 security areas and 4 service areas, stores a history of alarms and service events and uses authenticated, encrypted connections. ocBridge Plus offers professional-level configuration via USB and a Windows tool, and includes a backup CR2023 battery.

Suitable for

• Integrating Ajax detectors and sensors into IP-based or third-party security platforms
• Professional security system installations in offices, retail and multi‑floor buildings
• Remote monitoring and alarm forwarding for smart homes and commercial sites
