Connecting Alarm Signalling Devices - Bentel Security KYO 320 Installation Manual

[L1] / [2] to the terminal [+A1] and connect the detector
negative [L]/ [5] to an open-collector output as shown in
figure 16b. Program the corresponding output to termi-
nal [+A1] as: Monostable, Normally Closed, 20 sec-
onds ON Time. Assign the Output to an event that will
reset the Fire Detectors (e.g. Control Panel Reset or
Partition Reset).
In both cases the open-collector output must be pro-
grammed as Monostable, Normally Closed or 20 sec-
onds ON Time and assigned to an event that will reset
the Fire Detectors (e.g. Control Panel Reset or Partition
Reset). The connections described result in the power
supply to the Fire Detectors being cut off for 20 seconds
each time the event occurs, thus allowing the Detectors
to reset.

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 respective
terminal;
Ø Positive Alarm Line devices (e.g. Indoor Sirens) ac-
tivated by positive (12 V) on the respective terminal.
Ø Negative Alarm Line devices activated by negative
positive on the respective terminal.
Ø Balance Alarm Line devices activated by imped-
ance unbalance on the respective terminal.
The KYO320 is equipped with 6 Outputs expandable to
102 by means of the programmable Input/Output Ex-
pander:

INSTALLING
96 Outputs on 16 M-IN/OUT Expanders programmed
as Output Expanders (6 zones per Ex-
pander).
102Outputs Total
The three Outputs on the Main Unit (no. 1, 2, and 3)
comprise terminals:
Ø +N1, +A1, C1-NC1-NA1
Ø +N2, +A2, C2-NC2-NA2
Ø +N3, +A3, C3-NC3-NA3
The other Outputs on the Control Panel are made up of
terminals OC1, OC2 etc. The Outputs from the In-
put/Output Expander are marked [T1], [T2], etc.
The Standby status of the Outputs can be programmed
as follows:
Ø [+N] terminals can be connected to positive (13.8 V)
or can be open, and therefore can be used to activate
Intrinsic Security Devices;
Ø [+A] terminals can be open or connected to positive
(13.8 V), and therefore can be used to activate Posi-
tive Alarm Line devices;
Ø [C] terminals can be connected to their respective
terminals [NC] or [NA], and therefore, can be used to
activate all types of signalling devices;
Ø [OC] terminals (terminals [T] for the M-IN/OUT Ex-
panders programmed as Outputs) can be open or
connected to negative, and therefore, can be used to
activate Negative Alarm Line devices
+
The OC terminals on the Control Panel can switch
a maximum of 1 A, whereas terminals T on
M-IN/OUT Expanders can switch a maximum of
0.15 A. To switch larger currents use the Om-
nia/4R Relay Board.
