POWERING UP and ADDRESSING
COMPONENTS
This chapter explains how to address the various system components,
and perform the power-up routine.
A: ADDRESSING
SYSTEM
COMPONENTS
Before using the system, all
items connected to the RS-485
communications bus must be
allocated a unique address.
The number of components
that may be fitted is
dependent upon the model,
and is detailed on page 4-1.
NOTE: RS485 bus protocol does
not allow more than 30 devices
from being connected to the
bus. Development is under way
to permit additional devices to
be used for Euro-256 systems.
(i) KEYPADS
Keypads are addressed in
software after powering up –
see page 12-3.
(ii) Tag Readers,
Access Door Stations,
Guard Tour Points,
TMZs, Zone Expanders,
Output Modules
These are addressed by means
of selection switches fitted.
These must be correctly coded
before the system is powered.
Set Points –
Keypads, Tag
Readers, TMZs, Access Door
Stations and Guard Tour points
share a single number sequence
,
of which address 00 is normally
reserved for the primary system
keypad, which must be present
in order to commence
programming the system.
From these, the Keypads/Tag
Readers/TMZs with zone inputs
used MUST be at the “live”
addresses identified on page
13-7.
Zone Expanders and Output
Modules number from 00 in
individual number sequences.
NOTE: TMZ units are addressed in
the Set Point sequence as a Tag
Reader – see above.
