Description
Salva KNX TH and Salva KNX basic
are smoke detector sensors for the KNX build-
ing bus system. Their compact housing accommodates the sensors, evaluation circuits
and bus-coupling electronics.
The smoke alarm features an automatic evaluation sensor system for early and accu-
rate fire alarms. Alarms are output as a local acoustic signal and a bus telegram.
Salva
KNX basic
signals smoke alarm,
Salva KNX-TH
signals smoke and/or heat alarm.
AND logic gates and OR logic gates allow for a link between data and statuses. Multi-
functional modules change input data as required by means of calculations, querying
a condition, or converting the data point type.
The
Salva KNX TH
model additionally features integrated sensors for temperature
and air humidity. The measured values can be used for the control of limit-dependent
switching outputs. The devices have PI controls for heating/cooling (depending on
temperature) and for ventilation (depending on humidity).
Functions:
•
Smoke alarm sensors
with optical detection based on the scattered light
principle, certified according to EN 14604:2005/AC:2008 and 1172-CPR-150013.
Local acoustic alarm signal output (warning sound at least 85 dB) and transfer
to KNX bus. Local alarm acknowledgement
•
Signalling of
smoke alarm
•
Smoke chamber pollution measurement and pollution display according to UL
directive
•
Power supply via battery (9 V). Lack of battery capacity is signalled optically
and acoustically for 30 days and transmitted to the bus
•
High operative safety due to elaborate automatic self-testing of the entire
electronics and separate energy measurement
•
Faults signalled locally and via the bus
•
High deceptive alarm immunity due to powerful measuring chamber and
consideration of temperature fluctuations (though no temperature smoke
alarm)
•
8 AND and 8 OR logic gates
each with 4 inputs. All switching events as well
as 16 logic inputs (in the form of communications objects) can be used as
inputs for the logic gates. The output from each gate can be configured
optionally as 1-bit or 2 x 8-bit
•
8 multi-function modules
(computers) for changing the input data by
calculations, by querying a condition or by converting the data point type
•
4 actuating variable comparators
to output minimum, maximum or
average values. 5 inputs each for values received via communication objects
