Connecting The Telephone Line; Connecting A Power Supply - Bentel Security KYO 320 Installation Manual

Ø connect each Tamper contact to a 24h zone with 10
K or 10 K ALARM ONLY balance (see Fig. 22).
+
Tamper contact zones can be programmed with
Normally Closed balance, in which case, the 10 KW
resistors must not be connected.

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. 23.
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-

to Earth (e.g. automatic isolating switch).
The KYO320 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.
+
The control panel shuthdown the backup Battery
due to voltage drop (Safety threshold 9,6V), be -
cause this condition can damage the battery
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.
