The 750 hub card is fitted with two digital inputs for use when interfacing to volt free contacts.
These can be used for example with slam switches or a relay output from another system
such as a fire alarm panel. They appear during a FIND command on cable 0 (internal to the
hub card) and will have input addresses 1 and 2 assigned by default. Alarms can be set
against these two channels in the same manner as any other detector. Note these channels
are supplied linked out and will always be the first two channels on the control panel.

The four relays included on the hub
card can be assigned to alarm levels
in the relay alarm routine. They
appear on internal cable 0 during a
relay FIND.
All 4 relays are normally energised,
de-energising on alarm or on loss of
