Balance Type; Threshold - Bentel Security KYO 320 Installation Manual

Roller Blind This attribute must be assigned to Zones
used for Roller blind contacts. There are two trimmers
for sensitivity adjustment in the 'Roller Blind' section.
Pulse: This trimmer regulates the 'Pulse' threshold (1
through 7). The selected value will determine the num-
ber of 'Shocks' that the zone will allow before signalling
violation. Therefore, if Disable is selected, the corre-
sponding zone will be completely insensitive to Pulses.
Time: This trimmer regulates the 'Time' window. The
selected value will determine the 'Pulse' threshold time
(i.e. the time allowed for the Pulse counter to reach the
programmed threshold).
For example, a zone with a 'Pulse' threshold of 4 and a
'Time' window of 2 minutes, will signal violation when its
contact generates 4 Pulses within 2 minutes. If less
pulses than the programmed 'Pulse' threshold are gen-
erated during the 'Time' window, the zone will not signal
violation, but will refresh the window and carry forward
the memorized number of pulses minus one (e.g. 3
pulses memorized = 2 pulses carried forward). The win-
dow will be refreshed until there are no pulses to carry
forward, at which point, the 'Pulse' threshold and 'Time'
window will reset.
If the trimmer is positioned on 'repetitive', the number
of pulses (if less pulses than the programmed 'Pulse'
threshold) will be stored indefinitely. In all cases, the
'Pulse' threshold will reset automatically each time the
Control panel disarms.
n Balance Type
The Balance Type determines the electrical state (on
the Zone input terminal) that will trigger Alarms.
+
The following electrical states must be present on
the Zone Input terminals for at least 0.3 seconds.
Normally Open Zones with this attribute will trigger
Alarms when they short to Negative (e.g. Fire detectors).
Normally Closed Zones with this attribute will trigger
Alarms when they Open.
1K For Roller Blind and Vibration Zones. Control
panel will consider the Zone in standby status, when the
1 K resistor (1,000 ohm) is connected between the
Zone terminal and Negative. If a 1K Zone shorts to Neg-
ative, the Control panel will detect Tamper conditions
and generate the same following events of 10K Balance
Type.
10K If you apply this Balance Type, the Control panel
will consider the Zone in standby status, when the 10 K
resistor (10,000 ohm) is connected between the Zone
terminal and Negative. If a 10K Zone shorts to Nega-
tive, the Control panel will detect Tamper conditions
and generate the following events:
Ø Tamper on zone (relative to the zone concerned);
Ø Tamper alarm on partition no. and Generic+Tam-
per alarm on partition no. relevant to the Partition
the Zone is assigned to;
Ø Tamper alarm on panel and Generic+Tamper
alarm on panel;
KYO 320
In all other cases (Unbalancing, Open, etc.) the Control
panel will signal violation (refer to "Type").
Double If you apply this Balance Type, the Control
panel will consider the Zone in standby status when the
two 10 K resistors (10,000 ohm) are connected in paral-
lel between the Zone terminal and Negative.
If one of the resistors disconnects, the Control panel will
generate the events associated with the Zone Type (re-
fer to "Type"). In all other cases (Zone Open, Con-
nected to Negative, etc.), the Control panel will detect
Tamper conditions and generate the Events associated
with 10K Balance Zones.
This Balance Type (using 2 wires) will allow the system
to detect open Alarm and Tamper contacts (refer to
"Connecting to a Double Balance zone").
Glass Break You must apply this Balance Type to
Zones with Glass Break Detectors.
10K Alarm Only If you apply this Balance Type, the
Control panel will consider the Zone in standby status
when the 10 K resistor (10,000 ohm) is connected be-
tween the Zone terminal and Negative.
The Control panel will consider all other conditions as
violation (Zone open, short-circuit, etc.).
10K Alarm Only Balance Zones will signal Alarm sta-
tus when shorted.
10K Balance Zones will signal Tamper status when
shorted.
Customized You can customize this Balance Type to
suit the system requirements (refer to "Threshold").
n Threshold
The voltage threshold values will allow the Control
Panel to detect and distinguish Zone Alarm, Tamper
and Short-circuit conditions.
If you apply Customized Balance, you will be able to
select the various thresholds (Standby, Alarm, Tamper
and Short circuit).
Value in ohm This option will allow you to view the
zone terminal voltage values (instead of the threshold
% values).
Standby If you enable this option, the Control panel
will consider the Zone in Standby status when the volt-
age on its terminal is below the programmed Standby

threshold.

Alarm If you enable this option, the Control panel will
consider the Zone in Alarm status when the voltage on
its terminal exceeds the programmed Alarm threshold
for the programmed interval, and number of times (re-
fer to Sensitivity).
Tamper If you enable this option, the Control panel will
consider the Zone in Tamper status when the voltage
on its terminal exceeds the programmed Tamper
threshold for at least 0.3 seconds (300 ms).
