(vii) ZEM (ZONE EXPANDER) UNIT
For details of zone numbering, see page
4-5.
If a Zone Expander Unit is plugged onto
an Intelligent Power Supply, all
connections are automatically made to
draw current from the power supply,
and to use the system diagnostic
capabilities to control the power supply.
Do NOT therefore connect the +12v
terminal (D2) to the End Station, or to
any other item that is directly
connected to another power supply.
4-zone ZEM for use with Euro-12 has no
iD or Output terminals, and 4 EoL zone
inputs only.
For details of TMZ Zone Expander, see ‘ Tag Reader, on page 10 - 7.
Note: Before powering up, the Zone Expander
Unit must be addressed, using the coding
switches – open switches to add up to the address
required.
NOTE: When a ZEM is
used in iD mode, it MUS
T
be plugged onto a
n
Intelligent Power Supply,
unless used within 10
metres of the End
Station.
