Connecting a Keypad to the Bus
Keypad Addressing
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 27 for
instructions.
Backlight Control for i-KP01
You can control the appearance of the keypad
backlights and set/unset LEDs by fitting links over
the appropriate jumpers on the keypad PCB (see
Figure 7 on page 7 for the position of the
jumpers).
The jumpers have the following functions:
Note: To comply with PD6662:2010 at Grade 2,
disable the ABCD LEDs.
Backlight Control for KEY-K01/KP01/KPZ01
You can control the brightness of the keypad
backlights by fitting links over the BRIGHT jumper
on the keypad pcb (see 1b in Figure 11 or 6b in
Figure 13).
Jumper OFF The keypad backlights glow at
normal intensity.
Jumper ON The keypad backlights glow extra
bright.
To program whether the backlights are on or off
see below.
Programming Backlight, ABCD LEDs and
Navigation Key LEDs
You can set the function of the backlights in either
of two ways:
a) Use the Installer Menu – Detectors/Devices –
Wired Keypads – Edit Keypad – (Keypad n) –
Backlight option. See the Engineering Guide for
more details.
b) Enter a local keypad programming mode (this
replaces the use of jumpers on the keypad PCB in
the i-kp01).
In addition, the local keypad programming mode
allows you to enable or disable the LEDs in the
ABCD keys and the Navigation key.
It is possible to enter keypad programming mode
when the keypad is not connected to a control
unit, but simply powered by 12VDC connected to
the keypad bus terminal (see Figures 11 and 13).
If the keypad IS connected to a control unit then
make sure that the control unit is in Installer Menu
before entering the keypad’s local programming
mode.
