Code Relay Switch (Cosw); Use Of Door Sensors - Exit Button - Alphatech IP-VarioBell IPVB-01 Installation And Operating Instructions Manual

2.2.2 COde relay SWitch (COSW)

A code relay function is available for the switch (COSW-COdeSWitch). It
serves primarily to ensure the transmission of information on the electric lock
switching. When
using this function,
it is not possible to
activate this lock by
attaching
disconnecting
voltage to
electric lock leads.
Activation is only
performed when
the serial
information transmitted between the IP-VarioBell and the code relay switch
board is in agreement.
In the IP-VarioBell, you can set the Security code for the output to
activate the code relay switch board.
The code information is 8 bits, but the code entry is 4 bits with 4 bits of
security, which is a total of 8 bits. Practically, this happens by activating the
switch first by transmitting the serial code and if it matches, the code relay
switch board will connect the electric lock.
The code relay switch boards can be connected in parallel and thus
extend the number of switches, but you can never combine the electrical
lock and the code relay switch board in parallel !!
2.2.3 Use of door sensors – exit button
Maximum two door sensors can be connected to the IP-VarioBell
doorphone. It serves to re-transmit information on the closed door. This
information is displayed on the home screen (under the camera image) and
also it is transferred to the UDVguard applications. Another option is to use
SNMP.
The door sensor is either a part of the electric lock, or it is a conventional
magnetic contact used in the security systems. It is connected as an NC switch
on the terminal block (7) - just like the alarm magnetic contact (door closed =
closed).
Inputs for door sensors can also be used as exit buttons. In the IP-
VarioBell setting, you can select which switch controls this input. Actually, the
NO button is connected to the input and switches the switch in monostable
mode for the time period when the switch is switched on.
