Figure 45 shows an example of wiring a
tr
ouble/masking output using the “3-resistor
method”. Note that you must use 2k2 and 4k7
resistors as shown. Other values will not work
(See

in the
Menvier40/100/300 Engineering Guide).

Step 7. Connect Wired
Outputs
Figure 46 Connecting Wired Peripherals
Control Unit Wired Outputs
The control unit PCB provides three connectors
for wired outputs. Output 1 is a voltage free relay
output. Outputs 2 and 3 are driven by transistors,
and are capable of sinking a maximum 500mA
when active. By default outputs 2 and 3 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
Menvier40/100/300 Engineering Guide
.
Figure 46 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 46 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 7 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.
Auxiliary Tamper
The control unit provides two “AUX TAMP”
terminals that you can connect to external
equipment in order to detect a tamper. The
terminals offer CCL connection only. If you do not
intend to use them then connect the terminals
together with a short wire link.
If you wish to use FSL wiring for an auxiliary
tamper then it is possible to use a FSL wired zone
programmed as type “Tamper (10)”.
Wired Outputs on Expanders
Each EXP-W10 wired expander provides
connections for up to four transistor driven
outputs. 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
Menvier40/100/300
Engineering Guide
. Figure 47 shows an example of
using an expander output to drive an LED.
