2.6 Code relay (COSW)
For the switch (relay) 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 Brave and
the board code relay
Brave is set in several
codes to activate the relay code.
Relay can be activated codes
for one or two impulses can
differentiate activated from the
phone (DTMF) or from keys
(keyboard). The last option is
the activation code in another mode 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!
