2.2.1 Code relay (COSW)

For the first switch is available function code relay (COSW CodeSwitch).
It serves primarily to secure transmission of information by switching the
electric lock. When using this function is not possible connecting or
disconnecting the voltage at the terminals to lock this lock activated. Activation
is performed only when positive result compared serial information transmitted
between A-VarioBell and the board code relay.
The A-VarioBell is set
in several codes to activate
the relay code. Relay can
be activated codes for one
or two impulses
differentiate activated from
the phone (DTMF) or from
keys (keypad). The last
option is the activation
code in another
switch than the lock.
The code information is 8 bits, but the code is 4 bits with security 4 bits
which is total of 8 bits. Practically, this is performed so that after activation the
switch is first transmits the serial code, and if they agree, so code relay
connects the electric lock.
The code relays can be connected in parallel to increase the number of
switches, but can never combine connections electric lock and the code
relay parallel!
