If you wish, you canstart with one keypad connected to the bus,address that keypad, and then attach and addressother devices at later times. See “Initial Power Up”on page 29 for instructions.Backlight Control for i-KP01You can control the appearance of the keypadbacklights and set/unset LEDs by fitting links overthe appropriate jumpers on the keypad PCB (seeFigure 8 on page 7 for the position of thejumpers).The jumpers have the following functions:ONBRIGHTBLABCD-ONONBRIGHTBLONBRIGHTBLABCD-ONThe set/unset LEDsare disabled.ONBRIGHTBLABCD-ONONBRIGHTBLONBRIGHTBLABCD-ONThe set/unset LEDsshows the settingstatus of the system.(Full set is the lefthand LED.)

To comply withEN50131-1:2006 at Grade 3: disable the ABCDLEDs.Backlight Control for KEY-K01/KP01/KPZ01You can control the brightness of the keypadbacklights by fitting links over the BRIGHT jumperon the keypad pcb (see 1b in Figure 12 or 6b inFigure 14).Jumper OFF The keypad backlights glow atnormal intensity.Jumper ON The keypad backlights glow extrabright.To program whether the backlights are on or offsee below.Programming Backlight, ABCD LEDs andNavigation Key LEDsYou can set the function of the backlights in eitherof two ways:a) Use the Installer Menu – Detectors/Devices –Wired Keypads – Edit Keypad – (Keypad n) –Backlight option. See the Engineering Guide formore details.b) Enter a local keypad programming mode (thisreplaces the use of jumpers on the keypad PCB inthe i-kp01).In addition, the local keypad programming modeallows you to enable or disable the LEDs in theABCD keys and the Navigation key.It is possible to enter keypad programming modewhen the keypad is not connected to a controlunit, but simply powered by 12VDC connected tothe keypad bus terminal (see Figures 12 and 14).If the keypad IS connected to a control unit thenmake sure that the control unit is in Installer Menubefore entering the keypad’s local programmingmode.Entering Local Programming Mode1. Apply 12Vdc to the keypad.2. Enter Installer Menu on thecontrol unit, if thekeypad is connected to asystem.3. Open the keypad tamper.4. Press and hold down B and together for atleast two seconds.The keypad is now in localprogramming mode,the display shows thecurrent status.MENUABCD To Switch ABCD LEDs ON or OFF1. Enter local programmingmode (see above).MENUABCD 2. Press or to enable or MENUABCD
