Connecting Tamper Terminals - Bentel Security KYO 320 Installation Manual

Ø Tamper on supervised output — relative to the
Output;
Ø flashing on the a indicator on the Keypads.
+
The a indicator will flash until the cause of Alarm
is cleared (memory). The a indicator will stop
flashing when the Control panel resets.

Connecting Tamper Terminals

The Tamper contacts of the security system devices
can be connected to the 19 K Balance 24h Tamper
Line.
The Tamper Line terminal is marked ASB:
Ø The Tamper Line will hold Standby status when con-
nected to negative via a 10 KW resistor;
Ø The Tamper Line will trigger an Alarm under all other
conditions.
Alarm on the Tamper Line will be signalled by:
Ø a Tamper on Main unit event;
Ø flashing on the T indicator on Keypads.

INSTALLING
+
The T indicator will flash until the cause of Alarm is
cleared (memory). The T indicator will stop flash-
ing when the Control panel resets.
The wiring diagram in Fig. 21 illustrates the connection
of 3 Tamper contacts to the Main Unit Tamper Line:
Ø connect the device tamper contacts in series;
Ø connect a 10 KW resistor in series to the last Tamper
contact;
Ø connect one end of the series to the [ASB] terminal
and the other to the [M] terminal.
!
The 10 KW resistor must be connected to the
last device on the Output.
If the Tamper line is not used, connect a 10 KW
resistor across terminals [ASB] and [M].
+
If several contacts are connected to the Tamper
Line, the tampered device will be unidentifiable.
To identify tampered devices:
Ø select Double Balance for Motion detector connec-
tions (refer to "Double Balance" under "Connecting
Motion Detectors");
