Connecting the Telephone Line
In order to allow use of the Dialler, Digital communicator
and Teleservice facilities, the telephone line must be
connected to terminals [LE], as shown in Fig. 24.
This Control panel can detect Telephone line trouble
(Line down), which will be signalled when the voltage on
the [LE] terminals drops below 3 V for over 45 seconds.
Telephone line trouble will be signalled by:
Ø
the
Line-down
event;
Ø
ON status of the
G
indicator on Keypads;
Ø
flashing on the
i
indicator on Keypads.
The Control panel will signal restoral when the voltage
on the LE] terminals returns to 3 V for over 15 seconds.
+
If the telephone line
IS NOT CONNECTED
to the
Panel, the
Telephone line check
option must be
DISABLED
. If it is not Disabled, the Control panel
will signal Line-down status persistently (refer to
“Telephone” in the “PROGRAMMING” section).
Connect Line-sharing devices (Fax, Answerphone,
etc.) to the [LI] terminals. This will allow the Control
panel to take priority ONLY in the event of an alarm.
Connect the [
-
] terminal to the Mains Earth — this will
protect the PCB against surges from the Telephone
line.
!
Ensure that the Mains Earth is fully intact and
operating properly before connecting the Tele-
phone line.
Connecting a Power Supply
In order to comply with the Safety regulations in force,
the Mains must be equipped with a bipolar isolating de-
vice for protection against over voltage and short-circuit
to Earth (e.g. automatic isolating switch).
The KYO300 is powered from the Mains (230V/50 Hz)
through a Switching power supply, located inside the
cabinet. The cabinet can also house a backup battery
(not included) for power backup during Mains failure.
Programmed data will be protected at all times by the
RAM battery.
Mains failure will be signalled by the:
Ø
OFF status of indicator
28
on the Main board;
Ø
ON status of the
G
indicator on Keypads;
Ø
Warning Mains failure
event.
+
The
Warning Mains failure
event will be signalled
after the programmed delay (refer to “Filter Times”
in the “PROGRAMMING FROM PC” section).
The Control panel will monitor the battery at all times,
(refer to
Static Test
and
Dynamic Test
).
Static Test
The
Static
Test monitors the battery
charge during Mains failure.
Low battery
status (below
11.4 V) will be signalled by the:
Ø
Low battery
event;
Ø
ON
status of the
G
indicator on Keypads.
If this occurs, the Mains power must be restored before
the battery empties, otherwise, the system will shut-
down.
Low battery restoral (over 12.3 V) will be signalled by:
Ø
the end of the
Warning low battery
event;
Ø
OFF status of the
G
indicator on Keypad.
Dynamic Test
The
Dynamic
Test monitors the oper-
ating capacity of the battery. Failed Test (battery does
not meet the Test requirements) will be signalled by the:
Ø
Warning power trouble
event;
Ø
ON
status of the
G
indicator on Keypads.
If this occurs, the backup battery must be replaced im-
mediately, otherwise, the system will be unable to func-
tion in the event of Mains failure (black-out).
Battery trouble restoral
will be signalled by the:
