The JA-151ST-A Wireless combined smoke and heat detector
The JA-151ST-A is a component of the JABLOTRON 100 alarm
system. It is used to detect fire hazards in the interior of residential
or commercial buildings. The detector is powered by three LR6 type
alkaline AA batteries which are not included. We recommend buying
them with the detector. The detector indicates a fire hazard visually
using the built-in LED indicator and acoustic signalling.
The JA-151ST-A can acoustically indicate any other alarm such
as intrusion or tampering. The detector consists of an optical smoke
detector and a heat detector. The optical smoke 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
suc h as al co hol. That is why the f ire detector also contains a built-in heat
detector which has a slower reaction but is capable of detecting f ire with
a small amount of smoke. Th e detec tor has a status reacti on (reports
triggering and switching to stand-by mode). The product is not designed
to be installed in industrial premises. The detector should be installed
by a trained technician with a valid manufact u rer ’s ce rt if ic at e .
Detector location
The smoke detector must be installed in places where smoke can
eas ily dri ft int o the d etecto r owing to natural thermal circulation (us ually
towards the ceiling). The detector can be used only in enclosed
interiors. It is not suitable for areas where smoke can disperse and cool
down (for example rooms with 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
in some other suitable place is required, see Fig.2.

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.

acceptable location
Walls, partitions, barriers and lattice ceilings
The detector must be installed at least 0.5 m away from any wall
or partition. A narrow room with a width of less than 1.2 m requires the
detector(s) to be placed in the middle third of its width. If 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) ex ceedin g 5 % of the ceili ng heigh t
should be considered a wall and the limitations mentioned above should apply.
Ventilation and air circulation
The detectors must not be installed directly by ventilation or air
conditioning vents. In the case of air being supplied through
a perforated ceiling, there must be no perforation within the 0.6 m radius
of the detector in all directions.
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 humid areas (because steam, smoke or oily fum es can
cause false alarms or reduce detector sensitivity).
In areas with lots of small insects, which may cause false alarms
Warning: Most false alarms are caused by improper detector location.
See the CEN/TS 54-14 standard for detailed installation guidelines.
Installation
When installing the detector, abide by the procedures recommended
in the previous paragraphs.

In multi-storey flats and family houses the detector should be installed
above the stairs. It is recommended to place additional detectors in all
rooms where people sleep. See Fig 3.
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 warm layer of air on the ceiling. Never place the detector in the
corner of the room, there is an insufficient circulation of air. Always
install the detector at least 0.5 m distance from the corner, see Fig 4.

code is sent to the system which is confirmed with a short
flash of t he LED indicator (3).
4. Insert the detector into the plastic base. The detector can
be inserted into the plastic base in one position only. It is marked
with arrows (4) on both plastic parts. Close the detector cover
by turning it clockwise (2).
5. Set the detector according to the Detector setting chapter.
Note:
In order to perform enrollment via F-Link easier, we recommend
removing the production code sticker, placing it on some paper
and writing down the location before installing the detector
The detector can also be enrolled into the system by entering its
serial number (6) in the F-Link program. All numbers stated under
the bar code shall be entered (for example: 1400-0 0-0000-0001).
When necessary, the AN-868 external antenna can be connected
to the detector to boost communication.
Detector setting
The detector properties can be set up in the Devices window
in the F-Link program (*indicates factory settings).
The Reaction option in the Devices tab allows you to set the type
of reaction of the system to the activation of the enrolled detector.
To set the detector’s behaviou r, click on the Internal settings button
which will open up a dialogue window.

Fire alarm acoustic indication
Source of acoustic indication: sets the source of a fire alarm
indicated by the detector (*Switched off, Own alarm only, Own and
system alarm, System only).
Length limitation of acoustic indication: limits the duration of the
acoustic fire alarm indication of the detector (can be set from 1 to 5
minutes o r t o * No limit)
Fire alarm indicati on from s ecti ons: Determines which sections will
indicate a fire alarm via this detector.
Acoustic indication of other types of alarms:
Indicate another type of s ecti on alar m: Selection determines which
sections will indicate othe r types of alarm via the detector
Alarm reaction: Determines whether detector indication will
be dependent on a EW (External Warning) or *IW (Internal Warning)
signal.
Time limitation of a coustic section: *No limit, 1,2,3*,4,5 minutes.
“No limit” means that it will correspond to the alarm length set
in the control panel parameters Warning: the maximum alarm length
of the control panel is 20 minutes.
Muting the system sirens by pressing the detector: when
activated, pressing the detector against its base will cancel acoustic
indication of the system sirens. Options: Switched off, During its own
alarm, During a system alarm, *Switched on.
Batteries: it’s possible to choose the type of batteries used
in the detector (*alkaline, lithium).
Test: Pressing this button will trigger an automatic detector test.
The result of the test will be indicated by showing a green or red circle.
The green circle indicates a successful test. The red circle indicates
a fault, in this case repeat the test. If the fault keeps appearing, then
it’s necessary to send the detect or to the manuf ac tu r e r ’s serv i ce ce nt re.
Fire alarm
Optical detector: When smoke enters the detector, it triggers an alarm,
the red LED starts flashing fast (8x/s approximately) and alternatively
triggers acoustic indication, depending on the detector settings. Indication
lasts until the premises (the detector’s detection chambers) are aired out.
Heat detector: The temperature increasing above the fixed limit trigger s
an alarm, the red LED starts flashing fast (8x/s approximately)
and alternatively triggers acoustic indication, depending on the detector
settings. Indication lasts until the temperature is decreased, for example
by airing out the premises.
Muting the siren during an alarm: The integrated siren can
be muted by pressing the detector’s body against its base. The siren
is inactive for 10 minutes. If the detector still detects smoke or heat
then, the siren will be activated again.
When the need arises (e.g. in the case of detector failure),
it is possible to postpone siren reactivation by up to 12 hours. This can
be done by pressing the detector again for 5 s after muting the siren.
When the detector beeps, you have to release the pressure within 1 s.
The switchover to postponed siren mode is confirmed with 5 beeps.
The detector LED flashes all the time during the postponement.
Alarm memory: If enabled, the LED indication continues flashing
slowly (2x/s) to indicate a triggered detector for 24 hours after the alarm
has ended. Indication can be cancelled by unsetting the section where
the alarm had been triggered.
Tamper alarm: If the control panel isn’t switched to Service mode,
the detector will send a tamper signal to the control panel when
the detect o r ’s body is removed from its base.
Note:
If the detector is used in autonomous mode, any emerging danger
is indicated acoustically and visually. This cannot be changed
Another type of alarm
The detector is capable of indicating other types of alarms apart from
alarms triggered by the detector itself. They can be alarms (intrusion,
tamper, panic, 24h, etc) of both the IW and EW type. This can
be configured for particular sections, the alarm length can al so be limited.
Notes:
The indication of other types of alarm is also affected by
the settings parameters of the control panel (siren when partially
set, siren (IW output) when a tamper is triggered, etc.
When this detector triggers its own alarm it has a higher indication
priority. It will not indicate other alarms until its own triggered alarm
expires.
A fire alarm is always superior to other alarms. For example, when
a tampering alarm is in progress and a fire alarm is triggered,
the detector will stop indicating the first alarm and instead it will
start indicating the fire alarm immediately.
Detector testing and maintenance
The detector should be tested at least once per month. To test the
detector press the detector against the base and wait until an LED
indicator switches on. The LED flashing signals switchover to the test
mode . Th e LED is f lash es fo r the whol e du rati on 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 fault
is discovered, the detector beeps 3 times and the LED flashes 3 times.
In this case, repeat the test. If the fault still appears, send this detector
to a service centre. If the battery is low, there is no acoustic indication,
but just one fl ash when the test is co mp leted.
The complete functioning of the optical part of the detector can
be tested with a test 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 switched to Service mode, a fire alarm
is triggered.
Warning: Never test the detector by starting a fire in the premises.
Fault indication
The detecto r checks its own functionality. If it discovers a fault, the LE D
flashes and beeps 3 times and then flashes briefly 3 times every 30
seconds (a fa u lt found during the auto matic functionality te st is indica ted
the same way, see the Installation chapter). The fault can be
a malfunctioning detection chamber, the surrounding temperature out
of the operating temperature range (see Technical specifications) and other
detector faults.
An operating temperature fault will disappear when the surrounding
temperature returns to normal.
You can perform the detector test when it indicates a fault (see the D etector
testing and maintenance chapter) by refreshing information about
the measured temperature, smoke and dust particles in the chamber.
The measured data can be accessed in the F-link software,
Diagnostics tab. When the cursor hovers above the Status
of the detector a tooltip with the current information will appear.
Battery replacement
The detector checks the battery status, whether they are in use and
if the batteries are running low. The detector signals that they need
to be repl ac ed by s ho rt fl as hes (3 ) re pe at e d ev er y 30 s. Th e inf o rm at i on
is also sent to the control panel. Replace the batteries as soon
as possible with batteries of the same type and from the same
manufacturer.

Alkaline batteries are suitable for normal use. FR6 lithium batteries are
more suitable for installations, where the temperature is usually lower
than 5°C in the long term (batteries then have a shorter lifeti me ).
Do not throw used batteries into ordinary household waste.
Deposit them at authorized collec ti on points.
Removal of the detector from the system
The system reports any possible loss of connection with the detector.
If you have physically removed it on purpose, you also have to erase
it from the corresponding position in the control panel, see the control
panel installation manual.
Detector reset
This device can also be reset by a user. Resetting will revert it back
to factory default settings including erasing the control panel from
the detector’s internal memory.
A reset can only performed immediately after the batteries have been
inserted into the detector. A reset is done by pressing a button 5 times,
however the first press must happen within one second of the yellow LED
lighting up. It is visible through a grill on the detector. Each press is
confirmed by a beep and a successful reset will be confirmed by 5 brief
beeps at the end of the whole cycle.
Using an external antenna
It is possible to connect an external antenna (AN-868) to the detector
in order to increase communication stability between the control panel
and the detector. Insert the antenna into the connector (6)
on the detector’s PCB. The antenna will be det ected when the detector
is closed (the tamper contact is in standby mode). W hen the external
antenna is detected, RF transmission will be directed to it and
the detector will regularly check whether it is connected to the detector.
The moment the antenna is torn off or short-circuited, the RF
transmission will be switched to the internal antenna and a tamper
signal will be sent to the control panel. If the detector has been closed
without an external antenna connected, the RF transmission will
be permanently swit ched to the internal an t enna.
