User and service manual 13
1. Microphone (placed on the lower part of the motherboard)
– be careful of
the rubber seal of the microphone when changing the name tags, as the
improper assembly may affect the acoustics.
2. Peripheral Component Interconnect (PCI) connector to connect more
buttons/keyboard.
3. Connection point for a PC USB cable (as per NUDV).
4. LED indicator (placed on the lower part of the motherboard)
5. Speaker
– at the lower part of the motherboard
6. 12V AC/DC power supply for:
- relay controls;
- motherboard heating;
- name tag back lighting;
- internal power supply (DIP 3 a 4); and
- power supply for exit button circuit.
7. Relays
– are galvanically isolated, load is max. 48V, max. 1,5A
version
(C)
has 2-relays
version
(LC)
has 1-relay
on switch 1 is available relay function code (COSW - CodeSwitch) (see
page 25)
8. Exit button
– version
(C).
Works in current loop circuit, length of connected
conductors can be as long as 500m. To work there must be a 12V power
supply connected to the terminal (6).
9. Analogue telephone line (the polarity is not important).
10. Earth
– connection for an earth against static electricity – protecting the
electronics of the door entry system and telephone system.
11. DIP switch for both versions
(LC
and
C)
:
1 = Service
– for use when the password is
forgotten. Incoming call then enters
straight into programming where you
can se
t new password (don‟t forget to
switch it off again!); and
2 = Heating
– starts integral heating to stop
condensation
during
changeable
temperatures.
12. DIP switch in full version
(C)
:
3 = Integral power supply;
4 = Integral power supply
– always switches 3 and 4 at the same time. Power
supply is used from terminal 12V (6) and is used for 2 reasons:
- use of regime 7 or 8
– constant connection or disconnection of a relay is
possible only with integral power supply. Don‟t forget to also set
parameter 64.
- connection of the door entry system to the phone line switchboard that
has problem with power supply after switching on (Siemens). This
regime fully replaces the use of internal box Best Box; and
5 = Name tag back lighting (switches on/off LED name tag back lighting next to
the button).
