Extensions
VT7670 LTE slot modem
Allows to receive and send SMS notifications (2G, 3G). Provides Ethernet reservation over LTE (4G).
Extension slot
VT485r Reader extension
Allows to connect readers, and keypads with OSDP protocol support.
or
VT485m Modbus extension
Allows to monitor up to 32 Modbus RTU devices/meters/sensors.
Battery slot
VT-ACCU Rechargeable backup battery
Keeps the device operational while the main power source drops.The device uses two 3.7V rechargeable lithium batteries 14500. If the main power input voltage drops, the unit will work from VT-ACCU rechargeable batteries until the batteries are discharged.
or
VT-BAT Backup battery 9V
Keeps the device operational while the main power source is disabled. The device uses a non-rechargeable 6F22 9V lithium battery.
