CREATING A 4-ZONE INSTALLATION
Using two DRUID LCD 20 units, or a DRUID LCD 2x energizer and DRUID LCD 20 unit, a
four-zone installation can be created. Implementing four zones, a property owner can
identify the location of an attempted intrusion to a greater degree of accuracy. For
example, the front, back, left or right side of the property can each be a unique zone.
To create a four-zone system, the two units need to be linked via the keypad bus by
connecting the system ground (KEYPAD-) wires and the data wires (DATA) together (see
diagram on page 9).
One unit must be configured as a master, and the other unit configured as a slave. A unit
is configured by means of a Master/Slave jumper on the main PCB, just below the LCD
display. A master will have the jumper absent, and a slave must have the jumper inserted.
When a DRUID LCD 2x energizer and a DRUID LCD 20 are connected together, the DRUID
LCD 2x energizer must be set as the master and the DRUID LCD 20 as the slave to prevent
the energizer from generating a synchronisation loss fault.
Master will show as zones 1 & 2 on the keypad.
Slave will show as zones 3 & 4 on the keypad.
Lastly, the master needs to be informed whether a slave unit is connected, creating a four-
zone system or if it is a master only, two-zone system. This is to allow a communication
failure (service alarm) to be generated should the slave unit not respond to the master’s
request for information, and so that the keypad can be dealt with correctly as either a two-
or four-zone installation.
The
SLAVE UNIT PRESENT
setting is set by first entering installer mode, and then
entering installer code
5001*#
. Further details of this code can be found in this manual
under the
PROGRAMMABLE OPTIONS
section.
Note: Please read the section,
KEYPAD ZONE FOCUS
, in the Druid LCD 20 User Manual. This
section explains how to direct keypad inputs to a specific zone, or to all zones simultaneously.
Installer
PROGRAMABLE OPTIONS
which are zone focus specific will have the following text
appear bellow the programmable option later in this manual:
