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

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. 22.
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 KYO320 is powered from the Mains through a
Switching power supply, located inside the cabinet.
The cabinet can also house a backup battery (not in-
cluded) for power backup during Mains failure. Pro-
grammed 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 shutdown.
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.
