Note:
Supply Input Current:
The power requirement of 2.5 A is based on the following:
Host reader peak current @ 12 Vdc = 450 mA
Exit reader peak current @ 12 Vdc = 450 mA
Fully loaded DC output @ 12 Vdc = 1.6 A
Total = 2.5 A
This does not include anything that is connected to the DC Output.
DC Output Current:
The maximum guaranteed current that can be supplied from the 12 Vdc output.
Relay:
Nominal voltage and current that can safely be applied to the relay.
Comms to exit/DIU or
Comms to Host
If this unit is configured as a serial host reader, ‘HOST’ can be used as an
RS485 connection to the network.
If serial communications to a CEM product, such as the S700 or DIU, is
required, the ‘EXIT/DIU’ connection can be used as the connection to the
DIU or exit reader.
If the unit is configured as an exit reader ‘HOST’ can be used as a
connection to the host.
Input connectors Connection points for monitored inputs such as door position, lock sense
and Request to Exit switches.
