Fig. 24. Printer connection by means of 5-pin DIN plug (solder side view).
The control panel RS-232 port makes it possible to connect a printer provided with serial port.
The control panel may print events in a “compressed" format (single event is printed in
a single line containing up to 80 characters) or “extended" format, with names of zones,
partitions, users and modules (then, the event is printed in two lines, when the printer with up
to 80 characters per line is used; the descriptions of a single event are printed in one line with
printers printing 132 characters per line).
4.12 Connection of power supply
Before connecting power supply, make sure that all connection operations in
the system are completed.
Never connect two devices with power supply unit to one transformer.
Before adding transformer to a circuit from which it will be powered, make sure
the circuit is de-energized.
Because the transformer has no mains switch, it is important that you let the
owner / user of the device know how it should be disconnected from the mains
(e.g. by indicating the fuse which protects the control panel supply circuit).
It is not allowed to connect a fully discharged battery (with voltage across
unloaded terminals less than 11 V) to the alarm panel. If the battery is fully
discharged or it has never been in use, precharge it by means of a suitable
charger.
The INTEGRA 24 and INTEGRA 32 control panels must be supplied with 18 V (±10%)
alternating voltage. It is recommended that at least 40 VA transformer be used.
The INTEGRA 64 and INTEGRA 128 control panels must be supplied with 20 V (±10%)
alternating voltage. It is recommended that at least 60 VA transformer be used.
The transformer should be permanently connected to the 230 V AC mains. Thus, before you
set about making the connections, make yourself familiar with the electric system in the
facility. Make sure that the circuit you choose for powering the control panel will be always
alive. The power supply circuit should be protected with a proper safety device.
A 12 V lead-acid sealed battery should be connected to the control panel as an emergency
power source. The battery capacity must be adequately selected to match current
