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 30 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 30 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 31 shows an example of using
an expander output to drive an LED.
