INS176-15 33
60IXD Zone Expander
The 60iXD expander provides the following facilities:
• Two iD loops each supporting up to 30 biscuits
• Fused 12V output for powering detectors
• Engineer’s keypad port for local iD diagnostics
Installation
Before connecting the 60iXD expander module, isolate ALL power
from the control panel (AC mains and battery), do not continue if
there is still power present on the control panel.
1. Connect the iD expander to the control panel, see 60iXD
installation manual (INS261) for details.
2. Connect the iD devices to the expander module, see “iD
Connections”.
3. Reapply power to the control panel and program the
necessary options on the panel see 60IXD installation
manual (INS261) for details.
iD Connections
Each iD biscuit is connected across a two-wire detector loop. Apart
from observing the correct polarity, any wiring configuration can be
used, as shown in the diagram below:
* The 60iXD expander module is supplied with 4 off 10nF capacitors
in the spares pack. It is recommended that you connect a 10nF
capacitor approximately at the half way point of each iD spur. It is
especially important to do this on iD spurs that are less than 30
metres.
Cabling Considerations
The iD loop can be wired using standard 4-core alarm cable, this
allows 2 cores to be used for the iD biscuit and 2 cores for supplying
12V power for PIR's etc.
The number of biscuits that can be connected per cable run is
determined by the impedance of the cable used. Standard 4-core
alarm cable (7/0.2mm) has a resistance of approximately 8 Ohms per
100 metres. The following table shows the maximum number of
biscuits that can be connected at the end of a single cable run using
standard 4-core alarm cable:
If a different type of cable is used, the distances should be re-
calculated. e.g., if 7/0.4mm cable is used, a single run of 200m would
support 30 devices on the end as the resistance of the cable is
halved.
When installing the iD loop it is usually more practical to run several
cables from the expander module to the different areas of protection.
This effectively reduces any distance problems and makes fault
finding much easier.
To reduce the risk of induced interference and wherever possible,
cables should not be positioned alongside mains power, telephone
or other data transmission cables, or run within the same ducting or
trunking as any other cables.
The wiring for the system’s internal sounders (loudspeakers) should
not be connected in the same multi-core as the iD loop.
Biscuit Connections
Each iD biscuit is identified by its own number 01 to 30 and contains
its own internal sensor that is continuously monitored by the
expander module. The diagram below shows the connections to the
biscuit for monitoring both tamper and alarm contacts.
When the tamper switch is opened, the iD biscuit is taken offline and
a tamper condition is generated by the control panel. If the alarm
switch is opened the biscuit's internal sensor changes state and the
control panel will see this as an active condition and will respond as
appropriate.
The diagram below shows the typical wiring of a biscuit to a standard
PIR.
