Connecting Fire Detectors; Connecting Alarm Signalling Devices - Bentel Security KYO 320 Installation Manual

The wiring diagram in Figure 19 shows a typical con -
nection. The 1 K ohm Balance Resistor must be con -
nected to the last device.
Test vibration If the system has an LCD Keypad, it will
be possible to Test the sensitivity of the 'Vibration'
zones.
+
IMPORTANT - For the most reliable results, the
'Vibration' attribute must be disabled on all zones
except the one being tested.
n Connecting Fire Detectors
The KYO320 accepts Fire detectors with Alarm -Repeat
Outputs that operate at 12 V (e.g. BENTEL SECURITY
600 series). It is possible to connect the fire detectors in
three methods:
1)-use the Bentel MUB-RV Relay Base;
2)-see Fig. 17-2- for the wiring diagram.
Connect the Alarm-Repeat Outputs of the Fire detec-
tors to a FIRE zone (Normally Open — 24h), using a
diode in series as per Figure 17-2-.
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:
+A2+N2 +A1+N1

Assign the Output to an event that will reset the Fire detec -
tors (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.
3)- As per the second method, but using the Fig. 17-3-
for the wiring diagram. Connect the terminals [+A] (re -
lay) instead of terminals [+F]. Program also the associ -
ated output to relay as per the second method.

Connecting Alarm Signalling Devices

Alarm Signalling Devices, such as: Self-Powered Si -
rens, Indoor Sirens, Telephones Diallers, etc., can be
classified as follows:
