Connecting Motion Detectors - Bentel Security KYO 320 Installation Manual

192 Zones on 32 M-IN/OUT Expanders programmed
as Input Expanders (6 zones per Expander)
64 Zones on the Wireless Receivers
328 Zones Total
The Receiver zones (wireless zones) are for the wireless
detectors. The Main Unit, Keypad and Input/Output Ex-
pander zones (hardwired zones) are for the hardwired
detectors.
This section describes the connection of hardwired de-
tectors.
The terminals of the Main Unit and Keypad are marked
[L1], [L2], etc., while the terminals of the Input/Output
Expanders are marked [T1], [T2] etc.
The following terminals can be used for the power sup-
ply to the detectors:
either [+F] and [M] (negative) or [+F1] and [M] (nega-
tive), for each zone on the Main Unit.
13.8 V positive is present on Main Unit [+F] and [+F1] ter-
minals — protected by fuses 37 and 36 (F 1.85A).
[+F] and [M] (negative) for each pair of zones on
Keypads and the Input/Output Expanders.
13.8 V positive is present on Keypad and Input/Output
Expanders [+F] terminals — protected by resettable
fuse (0.4 A).
Each zone can support several detectors. However, if
more than one detector is connected, the Control panel
will be unable to identify the detector in the event of an
Alarm.
This system can detect Alarm, Tamper and Short-circuit
on hardwired zones:

The Zone status depends on several parameters (refer
to "Hardwired Zones" in the "PROGRAMMING FROM
PC" section). This section refers to the Balance type. If
only this parameter is considered, the zone status will
depend on the resistance between its terminal and neg-
ative, as shown in Table 2.
The following paragraphs describe the connections of
various types of detectors.

The 10 KW resistors have brown, black, orange and
gold bands. The last band (gold) indicates the toler-
ance, and therefore, may be a different colour.
n Connecting Motion Detectors
Most Motion detectors have Normally-Closed Contacts
(NC in the wiring diagram), and Normally-Closed Tam-
per Contacts (AS in the wiring diagram).
The zone balance can be programmed as:
– Normally Closed
– Normally Open
– 10 K
– 10 K Alarm
– Double
– Glass Break
The connection type depends on the selected balance.
