E: WIRING
RS.485 Communications
Terminals D1,3,4 should be
wired to the Euro-MERiDIAN
system as shown in Chapter 11.
NOTE: In default mode, the Door
Station communications section is
powered from the local Power
Supply. The D2 connection should
NOT therefore be used.
If a second Door Station is
being wired from the power
supply to provide two-way
access control through a door,
the full D1,2,3,4 connection is
required to the second unit.
The Access Reader
NOTE: The Access Reader cable
must be kept separate from
the lock supply connections.
The captive cable from the
Access Reader head may be
extended to a maximum of 100
metres. Recommended Cable
type is TWISTED PAIR. If a screen
is present, this should be
terminated to mains earth at
the Door Station only.
Care should be taken to ensure
that there is no earth leakage
on this cable.
Lock Supply Connections
The wiring to the lock
mechanism MUST be kept
separate from that for the
Access Reader head.
Use of properly terminated
screened cables for BOTH
connections may provide
sufficient isolation, separation is
preferred.
DC Lock mechanisms MUST
have back-emf protection
diode correctly fitted as
specified by the
manufacturer.
a) Using switched 12v supply
Max current: 2.5 amps for 15
seconds.
Voltage is permanently present,
and switched OFF to release the
mechanism.
Note the use of an emergency
break glass unit to release the
mechanism in the event of a fire or
other emergency.
b) Using volt-free relay
contacts
