JA-111ST-A BUS combined smoke and heat detector
{
This device is a component of the JABLOTRON JA-100 alarm
system. It is used to detect fire hazards in the interior of residential
or commercial buildings. The detector is powered by the control panel
BUS (EN 54-7; EN 54-5). When the detector is powered by inserted
batteries (3x 1.5 V AA) and it loses BUS power or stops communicating
with its control panel, it can continue operating as a stand-alone
detector when the 12 V BUS power supply is disconnected
(EN 14604). Batteries are not included and we recommend buying them
with the detector.
The detector indicates a fire risk using the built-in LED indicator and
acoustic signalling. The detector can also indicate any other type
of alarm in the system such as intrusion or tampering.
The JA-111ST consists of two independent detectors – an optical
smoke detector and a heat detector. The optical smoke detector works
on the principle of scattered light. It 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 works in status
mode so it signals both activation and deactivation. The product is not
designed to be installed in industrial premises. The product should
be installed by a trained technician with a valid certificate issued
by an authorised Jablotron distributor.
Detector placement
The smoke detector must be installed so that any smoke easily drifts
into the detector owing to natural thermal currents, e.g. on the cei ling.
The detector can only be used in an enclosed interior. It is not suitable
for places where smoke can be dispersed or it can get cold (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 Fig. 1. If the building has a floor area
greater than 150 m
suitable place is required, see Fig.2.

centre of the room, best location
acceptable location
Walls, partitions, barriers and lattice ceilings
The JA-111ST-A detector must not be installed closer than 0,5 m
from any wall or partition. A narrow room with a width of less than 1,2 m
requires the detector(s) to be placed at a distance of at least one third of the
room’s width away. In a case when a room is separated into sections with
walls, semi partition walls or furniture which do not reach the ceiling,
then each section must be consider as fully separated room 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 near ventilation or air
conditioning vents. In the case of air being supplied through
a perforated ceiling, each detector must be placed so that no perforation
hole occurs within 0.6 m of the detector.
Avoid installing the detector in the following places:
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 detector sensitivity).
in areas with lots of small insects which can cause false alarms
Warning: Most false alarms are caused by improper detector
placement.
See CEN/TS 54-14 standards for detailed installation guidelines.
Installation
When installing the detector, abide by the procedures recommended
in the previous paragraphs.

Installation on level ceilings
Place the detector in the centre of the room if possible.
The detector must not be recessed into the ceiling due to the possible
|
existence of a cool air layer on the ceiling. Never place the detector
in the corner of the room (always keep at least 0.5 m distance from
the corner - see Fig 4). There is an insufficient circulation of air
in the corners.

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.

1. Open the detector cover, by turning it anti-clockwise (1)
2. Push the BUS cable through the base and attach the base
to the selected place using screws.
3. Connect the BUS cable.
4. When the device is switched on, the yellow LED on the PCB
inside the detector starts flashing repeatedly to indicate that
the detector has not been enrolled into the system.
When connecting the detector to the
system digital bus, always switch the
power off.
5. Proceed according to the control panel installation manual.
a. Go to the F-Link software, select the required position
in the Devices window and launch enrollment mode by clicking
on the Enroll option.

b. Click to the option “Scan/add new BUS devices” and select this
detector from the offered list and double-click to confirm
selection. The yellow LED indicator goes off.
6. Insert the detector into the plastic base. The detector can be
inserted in the base in one position only. It is marked with arrows (4)
on both parts of the plastic housing. When inserting the detector,
bear in mind that the connecting wires must not restrain
the functioning of the test buttons.
7. Pre-set the detector functions according to the chapter Detector
settings.
Notes:
We recommend peeling off the sticker with the production code
(6) before you put it onto the mounting base, stick it on a piece
of paper and write down the device location for better
identification of a specific device when enrolling by F-Link
software.
The detector can also be enrolled by inserting into the mounting
base and locking by turning it clockwise when enrollment mode
is open.
The detector can also be enrolled into the system by entering
its production code (6) in the F-Link software (or using a bar
code scanner). All numbers stated under the bar code should
be entered (1400-00-0000-0001).
The detector can be operated without batteries. When there are
no batteries in it, it doesn´t comply with the EN14604 norm.
Before you insert the detector into the mounting base remove
the red blocking tabs from the detector body. The mounting base
must be replaced only by the same bases meant for detector
which is tested by pressing its body (which then works as testing
switch).
If the yellow LED lights permanently, the detector cannot
be enrolled and it indicates a fault with the cabling. We strictly
recommend checking the BUS cables.
Detector setting
The detector properties can be set in the Devices window in
the F-Link software (default settings marked by the symbol *):
The Reaction option in the Devices window allows you to set
the type of system reaction to the activation of the enrolled detector.
To set the detector properties use the internal settings button.
This opens a window where you can set internal settings and
behaviours of the detector.
Reaction: enables the setting whether the detector should react
on smoke only, temperature only, smoke or temperature, smoke and
temperature at the same time; see the following table for details:
Smoke EN 14604, EN 54-7
Temperature EN 54-5
*Smoke or temperature EN 14604, EN 54-5, EN 54-7
Smoke and temperature at once
Thermal class EN54-5 determines the reaction speed of the detector
to temperature increases.
*A1 – A fast reaction to temperature changes. It has to react within 1
min 40 sec when the temperature reaches 30 °C/s.
A2 – A slow reaction to temperature changes. It has to react within 2
min 25 sec when the temperature reaches 30 °C/s. These detector
settings have a high immunity to false alarms in problematical
installations.
Fire alarm acoustic indication:
Source of acoustic indication: Pre-sets the source of the acoustic
indication of a fire alarm signalled by the detector (Switched off, *Own
alarm only, Own and system alarms, System only).
Time limitation of acoustic indication: An option which serves for
time limitation of acoustic indication of a fire alarm by the detector;
optional from 1 to 5 minutes or No limit (*4 min).
Fire alarm indication from sections: Determines from which
sections fire alarms will be indicated.
Other alarm acoustic indication:
Indicate another type of section alarm: Selection of the sections for
which other alarm types and indications will be signalled.
Alarm reaction: Determines when the detector indicates according to
the *IW (Internal warning) or EW (External warning) signal.
Time limitation of acoustic indication: No limit, 1, 2, 3,*4, 5
minutes. When the No limit option is selected, it means the time is taken
from the system parameters. Caution: the maximum alarm length in the
system is 20 minutes.
Muting the system sirens by pressing the detector: This option
allows choosing how to react if the acoustic indication of an alarm from
the system sirens can be terminated by pressing the detector against
the base of the detector. Select from the following options: *Switched
off, during its own alarm, during a system alarm, Switched on.
Batteries: Select the type of batteries used (*alkaline, lithium)
or operating without batteries (the detector doesn´t check the status
of inserted batteries).
Test: By clicking on this button of the detector a self-test (auto test)
is performed. The result is indicated by a green or red dot. Green = test
OK, red = fault – in this case repeat the test and if you get the same
result then the detector should be sent to the service centre.
Fire alarm
Optical detector: When smoke gets into the detecting chamber,
an alarm is triggered and indicated optically by a flashing red LED
(approx. 8x per sec.) and if enabled then also by an acoustic signal
according to the detector settings. Indication takes place until the space
around it or the detecting chamber is ventilated.
Temperature detector: When the temperature increases above
a defined limit an alarm is triggered and indicated optically by a flashing
red LED (approx. 8x per sec.) and if enabled then also by an acoustic
signal according to the detector settings. Indication takes place until
the temperature is decreased by ventilation, for instance.
Silencing the siren during an alarm: The siren can be silenced
by pressing the detector body against the base. The siren is inactive
for 10 minutes. If the detector still detects smoke or heat after this time,
the siren is activated again. When the need arises (e.g. in the case
of a detector failure), it is possible to postpone siren reactivation
by 12 hours. This can be done by pressing the detector again for 5 s
after silencing the siren. When the detector chirps, you have to release
the pressure within 1 s. The switchover to the postponed siren mode
is confirmed with 5 chirps. The detector LED flashes all the time during
the postponement.
Alarm memory: When enabled, LED indication continues flashing
slowly (approx. 2x per sec) for 24 hours after alarm expiration.
Indication is terminated by performing unsetting procedure on already
unset section where the alarm was triggered.
Alarm memory in stand-alone mode indication can be terminated
by pressing the detector body against the wall.
Tamper alarm: When the detector cover is opened, the detector
sends a tamper signal to the control panel. To avoid tamper alarm
triggering enter service mode before opening the detector.
Note:
- When the detector works in stand-alone mode, an alarm is
indicated acoustically and optically with no option to change it.
Other alarms
The detector can indicate other alarms not just alarms triggered by the
detector itself. This includes alarms such as intrusion, tampers, panic,
24 hr and also in relation to IW and EW signals. Settings allow you to
choose specific sections and limits of the alarm length.
Notes:
The indication of other alarms is influenced by system parameters
(i.e. Siren when partially set, Siren IW when tamper triggered,…).
Its own alarm always has a higher priority. When its own alarm
is already being indicated then other alarms are not indicated at all.
A fire alarm has the highest priority. When a tamper alarm, for
instance, is triggered and suddenly a fire alarm is triggered then
indication of tampering is cancelled and it starts with fire alarm
indication immediately.
Detector testing and maintenance
The detector should be tested at least once per month. To test the
detector press the detectors body against the base and wait until a LED
indicator switches on. The LED flashing signals switchover to the testing
mode. The LED flashes for the whole duration of the test. When the test
is complete, the LED switches off. The detector then signals the result.
If the detector beeps once, the test has been done successfully.
If a failure is discovered, the LED flashes and beeps three times.
n this case repeat the test and if you get the same result then
I
the detector should be sent to the service centre.
there is no acoustic signalling but just one flash when the test
is completed.
The complete functioning of the optical part of the detector can
be tested with a testing spray (e.g. SD-TESTER). The heat sensor can
be tested with heated air (e.g. with a hair dryer). If the control panel
is not in the SERVICE mode, a fire alarm is triggered.
If the battery is low,
Warning: never test the detector with fire.
Fault indication
The detector checks its functioning. If it discovers a fault, it chirps and
flashes the LED three times and then flashes briefly three times every
30 s (a fault is signalled the same way when an auto-test is performed,
see the Installation chapt er). It could be a faulty detection chamber, an
environmental temperature out of the working range (see Technical
specifications) or some other fault detected in the detector.

JA-111ST-A BUS combined smoke and heat detector
A fault caused by a temperature out of range is restored automatically
when it gets back within limits.
A detector test can be carried out when a fault is signalled, see the
paragraph Detector testing and maintenance. During testing all the
measured information such as temperature, smoke and dirt in the detector
chamber are updated. The measured values can be monitored by F-Link
software in the Diagnostics tab. Hover the cursor over the option
Voltage/Loss and a tooltip appears with the current status of all measured
information.
Battery replacement
The detector checks the battery status if used and if the batteries are
running low, the detector signals that they need replacing by short
flashes repeated every 30 s. The information is also sent to the control
panel. Replace the batteries as soon as possible. Always replace all
three batteries of the same type and manufacturer.
Only use high-quality 1.5 V AA alkaline batteries. FR6 lithium
batteries are more appropriate for installation where the temperature is
below 5°C long-term or when the detector is simultaneously powered by
the system BUS and by batteries (then the batteries have a longer
lifetime).
Do not throw used batteries into ordinary household waste.
Deposit of them at authorized collection points.
Removal of the detector from the system
The system reports any possible detector loss. If you have removed
it on purpose, you also have to erase it from the correspondent address
in the control panel memory, see the control panel installation manual.
