When an alarm is enabled by an alarm input device attached to the alarm card,
an RS-485 alarm enabled broadcast message is generated by the alarm card.
The VOS-AL-8 is designed to be used with our range of UV90 cameras, giving greater
flexibility where preset activations are required.
With individually programmable contacts, the choice is far greater on devices to be
used, whether it is voltage free or PIR devices on your system.
