The JA-110ST Bus combined smoke and heat detector
The JA-110ST Bus combined smoke and heat detector 1 / 2 MLW51612
The JA-110ST is a component of the JABLOTRON JA-100 system.
It is used to detect fire hazards in a building interior. The product is not
designed to be installed outdoors or in industrial premises.
The JA-110ST consists of an optical smoke detector and a heat
detector. The optical smoke detector is very sensitive to large dust
particles which are present in dense smoke. It is less sensitive to
smaller particles generated by the combustion of liquids such as
alcohol. That is why the fire detector also contains a built-in heat
detector which has a slower reaction but is much better at detecting fire
which generates only a small amount of smoke. The detector has
a status reaction (reports its activation and deactivation). The detector
should be installed by a trained technician with a valid certificate issued
by an authorized distributor.
Detector location
The smoke detector must be installed so that any smoke easily drifts
into the detector owing to natural thermal circulation (usually on the
ceiling). The detector can only be used in enclosed interiors. It is not
suitable for interiors where smoke can disperse over a large area and
cool down (e.g. interiors with extremely high ceilings – above 5 m) – the
smoke would not reach the detector position.
The detector must always be placed in the section leading to the exit
of the building (escape route), see Figure 1. If the building has a floor
area greater than 150 m2, installation of an additional detector in some
other suitable place is required, see Fig.2.

In buildings and family houses with multiple floors, detectors
should be installed above stairwells. It is recommended to place
additional detectors in rooms where people sleep. See fig 3.
Installation on level ceilings
Place the detector in the center of the room if possible. The detector
must not be recessed into the ceiling due to the possible existence
of a warm air layer on the ceiling. Never place the detector in the
corner of the room (always keep at least a 0.5 m distance from the
corner) see Fig 4. There is an insufficient circulation of air in corners.
Installation on sloping ceilings
If the ceiling is not suitable for mounting on a level surface (e.g.
a room under a roof ridge), the detector can be installed as in Fig. 5.

Walls, partitions, barriers and lattice ceilings
The JA-110ST detector must not be installed closer than 0.5 m
from any wall or partition. A narrow space with a width of less than
1.2 m requires the detectors to be placed at a distance of at least one
third of its width away. In a case when a room is separated into
sections with furniture, racks or semi partition walls, which do not reach
the ceiling, the space is considered to be fully separated if the gap
between the top of these and the ceiling does not exceed 0.3 m.
A free space of at least 0.5 m is required under and around the
detector. Any irregularities of the ceiling (e.g. girders) exceeding 5 % of
the ceiling height should be considered a wall and the above-
mentioned limitations should apply.
Ventilation and air circulation
The detectors must not be installed directly by ventilation or air
conditioning vents, etc. If the air is supplied through a perforated
ceiling, there must be no perforation within a radius of 0.6 m of the
detector.
Avoid installing the detector in the following locations:
Places with poor air circulation (niches, corners, apexes of
A-shaped roofs, etc.)
Places exposed to dust, cigarette smoke or steam
Places with over-intense air circulation (close to ventilators, heat
sources, air conditioning outlets, etc.)
In kitchens and other cooking places (because steam, smoke or
oily fumes can cause false alarms or reduce detection faults).
In areas with lots of small insects
Warning: The most false alarms are caused by an
improper location of the detector.
See CEN/TS 54-14 standards for detailed installation guidelines.
Installation
Abide by the procedures recommended in the previous paragraphs.

When connecting the module to the bus,
always switch the system’s power off.
4. Proceed according to the control panel installation manual.
Standard procedure:
a. When the device is powered, the yellow LED starts flashing
repeatedly to indicate that the module has not been enrolled
into the system.
b. Go to the F-Link program, select the required position in the
Devices tab and enter the Enrollment mode by clicking on
the Enroll button.
c. Click on “Scan/add new BUS devices”, select the detector from
the list and double-click on it to confirm your selection.
The yellow LED light will stop flashing.
5. Insert the detector into the plastic base. It can only be inserted in
the position marked with arrows (4) on both plastic parts. Close the
detector by turning it clockwise (2). When the detector is fully
secured to the base, a control LED lights up (3), which indicates an
automatic detector test. During this period of time, the detector
won’t detect anything. The test ends when the LED shuts down (3)
and the detector becomes fully operational. A possible detector
fault may be indicated. See the Fault indication chapter.
Notes:
In order to facilitate identification when enrolling the detector
in F-Link, we recommend removing the sticker with a serial code
before inserting the detector into the plastic base. Paste it onto
a piece of paper and write down the location of the detector.
The detector can be also enrolled by entering the Enrollment
mode and inserting the detector into the plastic base.
Alternatively the detector can be enrolled by entering its serial
number (5) in the F-Link program. All numbers stated under the bar
code shall be entered (1400-00-0000-0001).
Detector settings
Go to the Devices window in the F-Link program. When you are at
the detector’s position, use the Internal settings option to open
a dialog window where you can set:
Reaction: it’s possible to choose whether the detector will react
to smoke, heat, smoke or heat or smoke and heat at the same
time.
Fire alarm
Optical detector: When smoke enters the detector, an alarm
is triggered, and it is signaled with a rapidly flashing red LED light
(approx. 8 times per second). The indication lasts until the detector’s
detection chamber is ventilated.
Heat detector: When the temperature rises above limit, an alarm is
triggered, and it is signaled with a rapidly flashing red LED (approx.
8 times per second). The indication lasts until the temperature drops
(e.g. when the room is ventilated).
Alarm memory: If enabled, LED alarm indication continues to flash
slowly (approx. twice per second) for further 24 hours after the alarm
stops. The indication can be terminated by unsetting the section in
which the detector is installed.
Tamper alarm: When the detector cover is opened, the detector
sends a tamper signal, unless the control panel is in Service mode.
Detector testing and maintenance
Fault indication
The detector checks its functionality. When a fault is discovered, the
LED indicator immediately flashes 3 times and then briefly 3 times
every 30 seconds. The automatic test indicates a fault the same way.
See the Installation chapter
The error found may be caused by a fault of the detection chamber,
the temperature of the environment being out of the operating
temperature range or other faults of the detector.
An operating temperature range fault will disappear the moment the
temperature of the environment turns back to normal.
Other faults found are indicated as a fault even after their cause has
gone. The fault indication can be stopped by the functionality test. The
basic functionality test is triggered by opening the detector cover (fig 6-
1), removing the lower plastic part and putting it back (fig 6-2). If this
test results in a fault again, send the detector to the repair service.
WARNING! The control panel must be switched to Service mode
otherwise a Tamper alarm will be triggered.

JABLOTRON ALARMS a.s. hereby declares that the JA-110ST is in a compliance
with the relevant Union harmonisation legislation: Directives No: 2014/30/EU,
2011/65/EU. The original of the conformity assessment can be found
at www.jablotron.com - Section Downloads.
Note: Although this product does not contain any harmful
materials we suggest you return the product to the dealer or directly
to the producer after use.
The functionality of the optical part of the detector can be tested with
a test spray. The functionality of the heat part can be tested with
a hairdryer. If the detector is configured to be triggered by both
conditions, it’s necessary to conduct both spray and hairdryer tests at
the same time. The test should be carried out once every 30 days. The
detector’s cover should be cleaned regularly from cobwebs and dust.
Test button: Pressing the test button will start the automatic
detector test. A result of this test is indicated by displaying a green
or red circle. The green circle means that the detector works
correctly. However the red circle indicates a fault of the detector. In
this case, repeat the test. If the fault appears repeatedly then it is
necessary to send the detector to the service for repair.
Warning: never test the detector with fire inside the building
