Installation manual

To provide ‘Local Audible’ Line Fault monitoring the RedCARE STU
MUST use the same telephone line as Comfort panel and should be
connected to the incoming line and NOT the outgoing line otherwise you
may suffer Line Faults on the RedCARE.
DualCom Connections
DualCom is connected slightly differently. For ‘Local Audible Line Fault’
monitoring, the telephone line MUST NOT share with the Comfort line in
any way, rather it must have it’s own telephone line connection.
Alternatively, DualCom may be run in radio-alone mode and secondary
path signalling may be provided by Comfort using the ‘Contact ID’
format (13). The line-fault relay from the stand-alone comms. device
must be connected to a Comfort zone programmed with a zone type 28
and named “Zone # Phone Tamper” . This relay should ‘open’ during a
line fault. This may also provide a line fault dial-out from the Comfort
communicator to a central station or user phones as usual, provided
Comforts telephone line is still operational. It is possible for the system
to be armed with this zone type active by bypassing the line fault zone
using the bypass menu.
Reporting Comfort Line Fault
If you need to monitor Comfort’s telephone line via Paknet or RedCARE,
switch an output using a response in alarm type 3 (line cut) and
connect it to an input channel of a stand-alone programmed for a
negative applied signal or via a 12v relay to reverse the polarity.
Obviously for this to be effective or even useful, the second comms.
unit must be on a separate and intact telephone line and the Paknet
radio-link must be fully operational at the time of the activation. Ensure
that the standalone comms. unit DC supply is taken from Comfort’s
auxiliary supply or is at least referenced to 0V ground.
Remote Reset - RedCARE /DualCom
In addition to using the Engineer *command to reset the system from
an external telephone, Comfort can be remotely reset by a central
station using the any external means capable of switching a relay such
as used by RedCARE Tellback or DualCom control relay. A volts-free
relay contact is connected to a Comfort zone input and programmed as
an idle ‘switch’ zone type (Type 8, 9 or 24) It’s ‘ON’ Response must
contain action code ‘25’ (Do Engineer Reset). The relay must change
state or pulse for at least 300ms.
Measuring System ‘Quiescent ‘ Current
The battery must remain in circuit when taking this reading and all
detection devices, Keypads, Door Phones and other devices requiring
power MUST be powered by the system while in ‘Security Off’ Mode and
free from wiring faults.
