Figure 47 Connecting Wired Peripherals
Control Unit Wired Outputs
The control unit PCB provides one connector for
wired outputs. Outputs 1 is driven by a transistor,
and is capable of sinking a maximum 500mA
when active. By default output 1 is 0V when
active, +12V when inactive. If you wish to reverse
the polarity of this output see
Changing the Polarity
of a Wired Output
in the
i-on Range Engineering
Guide
.
Figure 47 shows an example of using the wired
outputs to drive an indicator LED.
Wired External Sounders (Optional)
Wired external sounders differ in their methods of
connection. Figure 47 shows an example of a
general method of using the outputs to connect a
wired sounder.
It is possible to program the TR terminal on the
control unit (see item 2 in Figure 4) as either CC
or FSL. Use
Installer Menu – System Options – Panel
Tamper Rtn
. By default the terminal is CC. If you
program the TR terminal as FSL then make sure
you connect a 2k2 resistor in series with the wire
to the sounder.
Note: If you do not wish to connect a wired
external sounder then leave TR programmed as
CC and make sure you link TR to 0V on the
control unit. This prevents the control unit
reporting Bell Tamper unnecessarily.
Wired Outputs on Expanders
Each EXP-W10 wired expander provides
connections for up to four transistor driven
outputs. Each output has a maximum rating of
500mA (but note that the bus may not be able to
supply this much current). By default the outputs
are 0V when active, +12V when inactive. If you
wish to reverse the polarity of these two outputs
see
Changing the Polarity of a Wired Output
in the
i-on Range Engineering Guide
. Figure 48 shows an
example of using an expander output to drive an
LED.

Wired External Sounders on Expanders
Figure 49 shows a general method of using the
outputs on a wired expander to connect a wired
external sounder.
Connect the tamper wiring to an unused zone
connection on the expander. For 4-wire CC zones
use the alarm contacts only and link the tamper
contacts together with a short length of wire.
In the Installer Menu, program the zone with a
type of “Tamper”. Program the outputs used to
trigger the siren and strobe with the appropriate
output types. See the
i-onEX Range Engineering
Guide
for more details.
Single Wire Tamper Return
If the external sounder provides a single
–TR
connection, then use the zone type “Tamper
Return” for the zone terminals which receive the
connection at the expander.
