the battery "-". Connecting the common ground of the device to the battery "-"
will result in faulty operation of the charging current limiter, which will
eventually lead a quick discharge of the battery, or may even cause damage to
the control panel.
Connections of Telephone Line
If the control panel telephone communicator is used in the alarm system (for monitoring,
messaging or remote programming), it is necessary to connect telephone line to the control
panel. It should be led to a connector situated on the right side of the printed board. In order
to ensure proper messaging,
the control panel must be directly connected
to the line
(terminals designated as TIP and RING), and any other devices (telephone, telefax) – after
the control panel (terminals designated as T-1 and R-1). Such a connection will make it
possible for the control panel to fully engage the line for the time of calling, which prevents
the messaging function from being blocked by lifting the handset. Additionally, the telephones
connected after the control panel do not signal the dialing by the control panel.
The telephone line
must be a four-wire line so that the control panel can be connected
before the other devices (telephone, telefax, etc.).
Notes:
•
Do not send telephone signals and alarm system signals by one multicore cable. This may
result in damage to the system in case of a high-voltage punch-through from the telephone
line.
•
Telephone terminals of the panel should be connected to
PSTN (analog) lines only
.
Connecting the telephone circuit directly to digital network (e.g. ISDN) will cause damage
to the equipment.
•
The system installer should give the necessary information on the way of connection
control panel to telephone network to the user.
Connection of Voice Synthesizer
Where the function of alarm messaging with
voice announcements is used, a voice
synthesizer must be connected to the control
panel. The CA-6 interfaces with the SM-2
synthesizer produced by SATEL.
The synthesizer socket (designated as: SM-2
VOICE SYNTHESIZER) is located at the right
side of PCB, between telephone line
connector and low-current output sockets.
The SM-2 synthesizer should be directly
plugged into this connector. It is fitted with
minijacks for playback of the message and
monitoring of the telephone line.
Connection of power supply
The control panel is permanently connected to the mains supply source. Hence, before
making the connections it is necessary to familiarize with the electric system in the facility.
For powering the control panel choose the circuit which is always live. The power supply
circuit should be protected with a proper fuse.
