Visonic PG2 PowerMaster 33 ioXpander-12x4 Wired 12 Zone Expander (5-IOV00001)

The PowerMaster is Visonic's new line of wireless intruder alarm systems based on PowerG wireless technology.  PowerG PG2 redefines the wireless security market with a combination of reliability, performance and an advanced feature set.

PowerG PG2 combines several field-proven, advanced wireless technologies, like those used in cellular networks and Bluetooth, with the highly reliable AES encryption method.  The greatest innovation in PowerG is having these technologies operate on non-rechargeable batteries while still keeping all devices connected and online. Advanced signal jamming prevention with frequency hopping technology, this allows the system to identify interruptions in frequency and automatically adjusts to continue reliable communication.

The ioXpander-12x4 is a wired input/output expander that communicates with the PowerMaster-33 PG2.  Connect to the panel using an RS-485 Bus.
