The
DCBA keypad
jumpers
determine the address which is an additional tamper protection.
The pins D and A are shorted by default; it is possible to change the address (see: FS111,
FS124). The panel does not accept addresses of the „all closed” and „all open” type
addresses. The address is stored in the panel EEPROM (non-volatile) memory, together with
the other system parameters.
The
keypad
Z1 and Z2
terminals
permit connecting any detectors. They are supported by
the control panel in the same way as the mainboard zone inputs. The keypad Z1 terminal is
treated as zone 7, Z2 – as zone 8.
Provision is made for connecting additional keypads
(in parallel with the first one). Each
keypad should be connected to the control panel by means of a separate cable.
The
address of all keypads should be identical, the zone 7 and 8 can only be used in
one of them
, elsewhere they should be left open (nothing is to be connected).
There are two types of keypads designed to work together with the CA-6 control panel. All of
them should be connected in the way shown in Fig. 4 for the CA-6 KLED keypad. For
description of the CA-6 KLED-S terminals, see the figure below.
