Engineering Keypad
An Engineering Keypad is a modified i-kp01
that can be plugged into a dedicated
connector on the control unit pcb (see 17
on Figure 2) or any of the expanders (see
13 on Figure 8 or 10 on Figure 9). An
Engineering Keypad does not need to be
addressed, and will always be recognised
by the control unit.
You can use an Engineering Keypad to
program the system without being tied to
any of the installed keypads. If you wish to
move an Engineering keypad from one
connection point to another then you can
do so without removing power from the
system.
Step 4. Fit and Connect
Expanders
Both wired and radio expanders are
supplied in the same plastic case. Use M4
25mm countersunk screws in at least three
fixing holes when mounting the back of the
case on the wall. See Figures 8 or 9 for the
position of fixing holes and cable entries.
Connecting an Expander to the Bus
Both wired and radio expanders provide a
connector for the bus at the bottom of their
pcbs (item 4 on Figures 8 and 9 ) .
Figure 14 Wiring Expanders
Addressing Expanders
The control unit assigns addresses to all
devices connected to the bus cable. You
must start this process off once all bus
devices are connected, during the initial
power up. See page 20 for instructions.
Expander Loudspeakers
During normal operation loudspeakers on
expanders repeat setting and entry tones
for the partition that the expander is
allocated to. During an alarm the
loudspeakers repeat alarm tones.
