The “1” on the display tells you that this keypad is set to address 1. In this way it is possible to check the
address setting of the keypad. Also when the system is powered up, this message will appear in the display
for a few seconds.
Figure 8. Wiring diagram AlphaVision LED keypad
The AlphaVision NG LED keypad is recognized by the AlphaVision NG control panel by its different
version number, which is requested and made visible when powering up. For a LCD keypad this can for
instance be 1.8 and for a LED keypad this can be 5.4.
A LED keypad is set to address 2 to 8. A LED keypad can NOT be set to address 1, unless the LED keypad
is the ONLY keypad in the system. When powering up, the section LED on the LED keypad shows the
currently set address.
Up to 8 keypads can be connected onto the RS-485 bus. How many of these keypads are LCD and LED
keypads do not matter. The AlphaVision NG control panel can even be used with only one LED keypad. In
this case the LED keypad is set to address 1.
The functions of the OK, A, B, 230V and TEL LED’s on the LED keypad are identical to the functions of
the LED’s on the LCD keypads. Also the buzzers functions are identical. When a valid user code is entered,
the buzzer will sound once. When an invalid code is entered, you will hear three short beeps.
On the LED keypad you find the sections LED’s for sections A to H on the left side of the keys. These
LED’s show the status of the sections. With dipswitch 4 you can set these LED’s to function continually
(dipswitch to ON position) or only for a few seconds, after entering a valid user code.
A LED keypad can only be used for arming and disarming the system. It is not possible to execute functions
from this keypad. Only the numerical keys <0> to <9>, the <*> and the <#> key are placed on the LED
keypad.
