Glass Break Detectors - Bentel Security KYO 320 Installation Manual

Ø [NC] terminals are the Normally Closed Alarm Con-
tacts of the detector;
Ø [AS] terminals are the Normally Closed Tamper Con-
tacts of the detector.
Normally Closed The wiring diagram in Fig. 12 illus-
trates the connection of a detector to a zone with Nor-
mally Closed balance.
Normally Closed balance will allow the Control panel to
detect Alarm status on the zone:
– the zone will hold Standby status whilst connected to
negative;
– the zone will trigger Alarm under all other conditions.
To provide Tamper detection: connect the Tamper con-
tact of the detector to the Control panel Tamper Line, or to a
24h zone (refer to "Connecting Tamper Contacts").
10 K The wiring diagram in Fig. 13 illustrates the con-
nection of a detector to a zone with 10 K, or 10 K Alarm
Only balance.
!
The 10 KW resistor must be connected to the
last detector of the zone.
10 K balance will allow the Control panel to detect
Alarm and Short-circuit on the zone:
– the zone will hold Standby status when connected to
negative via a10 KW resistor;
– the zone will trigger short-circuit when connected to
negative;
– the zone will trigger Alarm under all other conditions.
To provide Tamper detection: connect the Tamper con-
tact of the detector to the Control panel Tamper Line, or
to a 24h zone (refer to "Connecting Tamper Contacts").
10 K Alarm Only The wiring diagram in Fig. 13 illus-
trates the connection of a detector to a zone with 10 K,
or 10 K Alarm Only balance.

10 K Alarm Only balance will allow the Control panel to
detect Alarm status on the zone:
– the zone will hold Standby status when connected to
negative via a10 KW;
– the zone will trigger Alarm under all other conditions.
Double The wiring diagram in Fig. 14 illustrates the
connection of a detector to a zone with Double balance.
This type of zone will allow the Control panel to detect
zone Alarm, Tamper and Short-circuit:
– the zone will hold Standby status whilst connected to
negative via a 5 KW resistor (i.e. using two 10 KW resis-
tors connected in parallel);
– the zone will trigger short-circuit when connected to
negative;
– the zone will trigger Tamper when open;
– the zone will trigger Alarm under all other conditions.

To provide Tamper detection on zones with Normally
Closed or 10 K balance:
either connect the detector tamper contact to the Con-
trol panel Tamper Line — this type of connection does
not provide identification of the tampered detector;
or connect the detector tamper contact to a 24h zone —
this type of connection requires two zones — one for
Alarm detection, and the other for Tamper detection (re-
fer to "Connecting Tamper Contacts").

INSTALLING
The 10 KW resistor must be connected to the
last detector of the zone.
Zones with Double balance can detect and signal
Alarm and Tamper by means of just two wires.
