Auxiliary Tamper
These two terminals provide tamper protection
to auxiliary devices such as power supplies,
extension loudspeakers etc. If they are not used
they must be linked out.
Extension Loudspeakers
Up to two extension loudspeakers can be
connected across the [SPK+] and [H/O-]
terminals on the control panel PCB. The volume
for the loudspeaker is controlled by VR1
“Speaker Volume”.

Digicom/RedCARE Installation
Connect a digital communicator, RedCARE STU
or Paknet interface card to the control panel
using the following connections:
Digicom Outputs 1 to 8
These are the programmable digicom output
connections. They are normally at +12V and
switch to 0V when active. The outputs can be
inverted so that they switch from 0V to +12V
when active
(see System Configuration on
page 34 )
. Each output will source 5mA in the
+12V condition and sink 100mA in the 0V
condition.
Alternatively, fit a plug-on STU to JP9 and JP10.
This uses Digicom outputs 1 to 7 for Channels 1
to 7. Note that Channel 8 on this interface is
dedicated to “Low Battery”. You
MUST
remove
the "CS" link at JP7 before fitting a plug-on STU to
ensure correct operation of Remote Reset via
RedCARE.
+DC POWER
This provides the +12V power to the digicom.
This output is un-fused and therefore should only
be used if the digicom is fitted inside the control
panel. Use any of the auxiliary 0V terminals for
the 0V supply for the digicom/STU.
LINE FLT
If an external device switches this input to +12V,
the control unit generates a “Line Fault”. If a
“Line Fault” occurs while the system is unset then
the control unit generates a “Chime”every
minute. If a “Line Fault” occurs while the system
is set then the control unit cancels the “Bell
Delay”.

Plug-on Digicom Installation
A plug-on digital communicator DC54 or DC58
may be fitted inside the control panel to allow
alarm status information to be transferred to a
dedicated central station. The unit should be
fitted in accordance with the installation
instructions supplied with it and connected to
the control panel plug DIGI-MODEM (JP3) using
the lead provided with the unit,
see Figure 20
.
The NVM within the digicom can either be
programmed via the control panel,
see page
52.
or directly using an engineer's keypad
plugged into the digimodem.
