2 Description
Smoke alarm Salva KNX • Version: 30.01.2017 • Technical Changes and Errors excepted.
This document describes the functions for ALL device models.
Please check the information at the beginning of the chapter and in the
text which describes the functions available for the respective individual
models.
1. 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

4 Installation and commissioning
Smoke alarm Salva KNX • Version: 30.01.2017 • Technical Changes and Errors excepted.
* Please note the information on Accuracy of temperature/humidity measurement, page 4
1.1.1. Accuracy of temperature/humidity measurement
Only for Salva KNX TH model.
Measured value deviations for temperature and humidity due to sources of interfer-
ence (see chapter Installation location) must be corrected in the ETS in order to ensure
the specified accuracy of the sensor (offset).
During temperature measurement, the self-heating of the device is taken into con-
sideration by the electronics. The software compensates the self-heating by reducing
the measured temperature. During the 2 hour warm-up phase, the displayed interior
temperature measured value increasingly approaches the actual room temperature.
2. Installation and commissioning

Never expose the device to water (e.g. rain) or dust (e.g. drilling dust). This can damage
the electronics and the sensor system. A relative air humidity of 93% may not be ex-
ceeded. Avoid condensation.
After the bus voltage has been applied, the device will enter an initialisation phase last-
ing a few seconds. During this phase no information can be received or sent via the
bus.
2.4.2. Assembly preparation and skirting assembly
Determine the installation point on the room ceiling. Please observe the instructions in
chapter Installation location, page 5 for this.
BEWARE!
Injury hazard in case of improper fastening!
The device may fall and injure people if it is not fastened properly.
• Observe, the carrying capacity of the wall/ceiling material when
selecting the place of installation.
• Use fixing materials that are suitable for the material underneath.
If you are using the screws and dowels provided, use a 6mm drill to drill holes with a
distance of 67 mm (if you are using two screws for installation). Use the skirting of the
smoke alarm as a stencil. Insert the dowels into the drilling holes.
As an alternative, the skirting of the alarm may be attached to the ceiling with double-
sided adhesive pad (VdS approved). Carefully check the ceiling surface carefully for
lasting carrying and adhesive capacity before using adhesive pads. If necessary, do a
test glueing application. Optimum adhesive power can only be obtained on a clean sur-
face.
