FULL LCD KEYPAD INSTALLATION
INSTALLATION
Connect the 4 wires from the keypad bus on the main control panel to the corresponding connections on the keypad
(DAT, CLK, POS & NEG) The 5th wire is an optional “Listen-in“ connection. It is connected from the "Input" terminal
of the keypad to the "Lin" terminal of the panel keypad port. With the Listen-in wire connected the user can hear the
call progress during dialling at the keypad (provided the desired program options at address P175E 6E are turned
on). The keypad input must not be set as a zone (P122E option 4) for the listen-in feature to work.
The maximum recommended cable distance using standard 0.2mm security cable is 50m, or 100m using 0.5mm se-
curity cable. For longer cable runs there is a keypad bus extender module available.
FULL LCD KEYPAD ADDRESS ASSIGNMENT
A total of 32 devices (keypads or wiegand interface modules) can be connected to the panel. Each keypad must be
addressed individually to avoid BUS conflicts when multiple users are operating different keypads simultaneously. By
default, each keypad comes addressed as KP # 1.
Setting the LCD keypad address is done in “Local Program Mode”.
To enter
“Local Program Mode”
on the
FULL LCD
Keypad you must press <PROGRAM> then <BYPASS> then
<ENTER> (sequential button entry). The display will show “keypad number” and the currently assigned keypad ad-
dress number will be shown.
By pressing any number from 01-32 then pressing <ENTER> the keypad will change it’s address to the new entry
and automatically exit Local program mode.
If you do not assign a unique address to every keypad and reader connected to the keypad buss, a conflict
will exist that will cause erratic operation. Each reader or keypad MUST have a different address.
FULL LCD KEYPAD ZONE INPUT
On the FULL LCD keypads there is a spare terminal labelled “Input”.
This input can be used for listening in when the dialler is active or as a zone input linked back to the main panel.
The zone associated with the keypad input is linked to the keypad address, eg if the keypad address is set to 23 the
input on the keypad will be linked to zone 23.
If the zone input at P122E has option 4 turned off the keypad input is used for the listen in function.
If option 4 is turned on the input will work as the associated zone input, eg if the keypad address is set to 23 and op-
tion 4 is turned on at P122E 23E the keypad input will work as zone 23 sending sealed and unsealed status back to
the panel.
