negative;
– the zone will trigger Tamper when open;
– the zone will trigger Alarm under all other conditions.

Zones with Double balance can detect and signal
Alarm and Tamper by means of just two wires.
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”).

Glass Break Detectors
Fig. 18 illustrates the connection of 3 Glass Break de-
tectors to a zone with Glass Break balance.
!
Glass Break zones accept up to 20 detectors.
The continuous lines in the wiring diagram represent
the soft-soldered conductors of the detector, and the
broken lines represent the copper wires.
Connect the Glass Break detectors in parallel between
the zone and negative, and a 10 k
W
resistor in parallel
to the last detector.
This balance type will allow the Control panel to detect
Alarm, Tamper and Short-circuit on the zone:
– the zone will hold Standby status whilst connected to
negative via a 10 K
W
resistor;
– 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.

Connecting Fire Detectors
The KYO300 accepts Fire detectors with Alarm -Repeat
Outputs that operate at 12 V (e.g. BENTEL SECURITY
RT101, RT102 and RF501t).
See Fig. 19 for the wiring diagram.
Connect the Alarm-Repeat Outputs of the Fire detec-
tors in parallel to a
FIRE
zone (
Normally Open — 24h
).
Connect the positive supply terminal of the detectors to
terminals
[+F]
.
Connect the negative supply terminal of the Fire detec-
tors to an Open-Collector Output programmed as:
–
Monostable
– Normally Closed
– 20 seconds ON Time
Assign the Output to an event that will reset the Fire de-
tectors (e.g. Reset Panel or Reset Partition).
In this way, when the programmed event occurs, the
negative power supply to the fire detectors will be inter-
rupted for 20 seconds thus resetting the Fire detectors.
Connecting Alarm Signalling Devices
Alarm Signalling Devices, such as: Self-Powered Si-
rens, Indoor Sirens, Telephones Diallers, etc., can be
classified as follows:
Ø
Intrinsic Security Devices
(e.g. Self-Powered Si-
rens) activated by voltage failure on the relevant ter-
minal;
Ø
Positive Alarm Line
devices(e.g. Indoor Sirens) ac-
tivated by positive (12 V) on the relevant terminal.
