Connection to RedCARE or DualCom
Some installations may require ‘Line Fault Reporting’ such that the
Central Station is informed when a ‘line cut’ has occurred using means
other than the telephone line that has been cut. A stand-alone
RedCARE STU or DualCom Paknet interface card may be installed to the
system to transfer alarm status and line fault information to a central
station using a radio method or ‘loss of carrier’ method. These devices
are triggered using Comfort’s outputs and alarm types.

Figure 2.15 - Output Connection to STU
Using Outputs (1-6) The outputs are normally at +12V and switch to
0V (negative applied) in alarm condition and can supply up to 200mA.
They cannot be inverted except by using a relay. The outputs are
controlled from responses (table 33) inserted in the alarm types menu
in table 18. Some of these responses may require the action code ‘20’
inserting within, creating an Engineer Reset requirement upon
activation. (e.g Intruder Alarm, Armed Tamper and Siren Tamper Alarm
conditions).
The outputs are normally programmed as latching ‘ON’ = negative
applied using action code 128. So when programming the ‘ON’
responses ensure that the outputs are also switched OFF afterwards
using a multiple string command (outputs 1- 6 OFF) when the system is
disarmed to ‘Security OFF’ Mode. This is achieved entering the relevant
Response into alarm type 19 ‘System Open’.
RedCARE and DualCom cannot transmit sequential zone information to
the central station at present unlike Comfort which uses ‘Contact ID’
sequential reporting. To improve upon this Comfort’s Alarm Filtering
may be used to differentiate between a single zone activation and
multiple zone activation.
With Comfort, when two different zones which are programmed as
‘alert zone’ types are triggered within 10 minutes, an intruder alarm is
produced. So by setting internal zones as ‘Alert Types’ such that when
more than one Alert Zone is triggered within 10 minutes an Intruder
