terminal and the black wire to the B (negative) terminal. When 
using end of line supervision, connect the zone according to one of 
the configurations outlined in your system’s Installation Manual. 
4. If the ‘P/Z’ terminal is programmed as an output, the output follows 
the PGM programmed in Section [080]. A small relay, buzzer or 
other DC operated device may be connected between the positive 
supply voltage and the ‘P/Z’ terminal (maximum load is 50mA). 
Applying Power
Once all wiring is complete, and the equipment is secured to the building structure with at least two screws apply power to the control panel:
1. Connect the battery leads to the battery.
2. Connect the AC transformer. 
For more information on control panel power specifications, see the 
control panel Installation Manual.
Programming the Keypad
There are several programming options available for the 
keypad. These are described 
below. Programming the keypad is similar to programming 
the rest of the system. When 
you are in the keypad programming sections, the keypad will display which options 
are turned on along the top of 
the display. To turn an option 
on or off, press the number corresponding to the option on the number 
pad. The numbers of the options that are currently turned ON will be 
displayed. For example, if options 1 and 4 are on, the display will 
look like this on the different keypad displays: 
For information on programming the rest of your security system, 
please refer to your system’s Installation Manual.
Broadcasting LCD Labels
All LCD programming is done per keypad. If more than one LCD keypad is present on the system, labels programmed at one keypad can 
be broadcast to all other LCD keypads. Perform the following procedure 
in order to broadcast labels: 
Step 1 - Program one LCD keypad completely. 
Step 2 - Make sure all LCD keypads are connected to the Keybus. 
Step 3 - Enter keypad programming by pressing [,][8][Installer 
Code][,], then enter section [998] at the keypad that was programmed. The keypad will now broadcast all the information programmed to all the other LCD keypads on the system.
Step 4 - When the keypad is finished press the [#] key to exit.
NOTE: Label broadcast from this keypad is only compatible with other 
PK5500 and RFK5500 Keypads.
Language Programming 
(PK5500\RFK5500 Only)
Hold (<>) keys for 2 seconds to enter language programming, 
scroll to the desired language and Press [
,] to select.
NOTE: If section [077] option 4 is OFF, language programming 
can only be performed while in installers programming.
Enrolling the Keypad
The keypad will need to be assigned to a partition and slot if supervision or keypad zones are being used. Keypad assignments and keypad option programming must be done at each keypad individually. 
The 1st digit of keypad assignment is used to determine partition 
assignment (1 to 8). If partitioning is not used, enter [1]. For Global 
Keypads, enter [0].
NOTE: LED and ICON keypads cannot be programmed as Global Keypads
The 2nd digit of keypad assignment is used to determine slot assignment for keypad supervision. Each keypad will be assigned a different 
slot number from 1 to 8. PK5500 and RFK5500 LCD keypads come 
defaulted in slot 8. If LCD keypads are used one LCD keypad must 
remain in slot 8.
NOTE: The RFK55XX enrolls as two modules: 
Light 1 = keypad section of the RFK55XX 
Light 17 = receiver section of the RFK55XX 
NOTE: Deleting all wireless devices from the RFK55XX or defaulting the 
RFK55XX will cause a supervisory fault.
Enter the following at each keypad installed on the system:
1. Enter Installer Programming by pressing [,][8][Installer’s Code]
2. Press [000] for Keypad Programming
3. Press [0] for Partition and Slot Assignment
4. Enter the 1st digit (0 to 8 for partition assignment)
5. Enter the 2nd digit (1 to 8 for slot assignment supervision)
6. Press the [#] key twice to exit programming.
7. After assigning all keypads, perform a supervisory reset by entering 
[,][8][Installer’s Code][902] and wait for 60 seconds.
8. Press the [#] key to exit programming after 60 seconds.
Programming Labels 
(PK5500\RFK5500 Only)
1. Enter keypad programming by pressing [,][8][Installer Code][,]. 
Enter the 3-digit section number for the label to be programmed.
2. Use the arrow keys (<>) to move the underline bar underneath 
the letter to be changed. 
3. Press the number keys [1] to [9] corresponding to the letter you 
require. The first time you press the number the first letter will 
appear. Pressing the number key again will display the next letter.
4. When the required letter or number is displayed use the arrow keys 
(<>) to scroll to the next letter.
5. When you are finished programming the Zone Label, press the [
,]
key, scroll to “Save,” then press [
,].
6. Continue from Step 2 until all Labels are programmed.
