The JA-151ST Wireless combined smoke and heat detector
The JA-151ST Wireless combined smoke and heat detector 1 / 2 MLW55806
The JA-151ST 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 can be installed in
mobile homes or caravans. The product is not designed to be
installed in industrial premises. The JA-151ST detector uses
wireless communication and it is powered with three AA batteries.
The detector should be installed by a trained technician with a valid
with a valid manufacturer’s certificate.
The detector indicates a fire hazard using the built-in LED
indicator and acoustic signalling.
The JA-151ST consists of two independent detectors – an optical
smoke detector and a heat detector. The optical smoke detector
works on the principle detection 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.
Detector range and location
The smoke detector must be installed so that any smoke easily
drifts into the detector owing to natural thermal currents, e.g. on the
ceiling. It is suitable for residential buildings but not suitable for free
spaces, outdoor environments or interiors with extremely high
ceilings (above 5 m) where fire by-products can disperse over a
large area – the smoke would not reach the detector position.
The detectors should be installed by a trained technician with a
valid manufacturer’s certificate.
Detectors should be installed in the building according to the
project documentation. If such documentation is not available, their
position should comply with the effective standards for fire alarm
signalling systems.
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 m2, installation of an additional detector
in some other suitable place is required, see Fig.2.

acceptable location
In multi-storey flats and family houses the detector should be installed
above the stairs. It is recommended to place additional detectors in
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 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.
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-151ST 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 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. 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 locations:
xplaces with poor air circulation (niches, corners, apexes of A-
shaped roofs, etc.)
xplaces exposed to dust, cigarette smoke or steam
xplaces with over-intense air circulation (close to ventilators,
heat sources, air conditioning outlets, etc.)
xin kitchens and other cooking places (because steam, smoke or
oily fumes can cause false alarms or reduce detector sensitivity).
xbeside fluorescent lights or energy-saving light bulbs (electrical
interference can cause a false alarm)
xin areas with lots of small insects
Warning: Most false alarms are caused by improper detector
location.
See CEN/TS 54-14 standard for detailed installation guidelines.
Installation
When installing the detector, abide by the procedures
recommended in the previous paragraphs.

4. Proceed according to the control panel installation manual.
Basic procedure:
a. There must be the JA-110R radio module enrolled in the
system.
b. Go to the F-Link program, select the required position in the
Devices window and launch enrollment mode by clicking on
the Enroll option.
c. When you insert all batteries into the detector, an enrollment
code is sent to the system – its sending is confirmed with a
short flash of the LED indicator (3).
Note: The detector can also be enrolled into the system by
entering its serial number (5) in the F-Link program or using a bar
code scanner). All numbers stated under the bar code shall be
entered (1400-00-0000-0001).
5. 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).
Note: Detector cover closing is blocked unless all 3 batteries
are inserted!
The mounting base must not be replaced by bases meant for
detectors without the test button consisting of pressing the
body of the detector.
Detector setting
The detector properties can be set in the Devices window in the
F-Link program or with configuration terminals.
The Reaction option in the Devices window allows you to set the
type of reaction of the system to the activation of the enrolled
detector. The configuration terminals on the detector PCB
determine other reactions:
SIR enables deactivating the built-in siren.
MEM alarm memory signalling – if enabled, the detector LED
remains active for an additional 24 hours Signalling can also be
terminated by pressing the detector body against the base.
SMOKE and TEMP combination of these terminals defines
whether the detector will react to smoke and heat.
Fire alarm
A fire alarm is signalled acoustically and optically according to
the settings.
When the conditions for fire alarm triggering are met (smoke is
detected in the room, the alarm temperature is reached, or both
conditions are met), the detector signals the danger by sounding
the siren and quick flashing of the LED indicator (3). The alarm
information is concurrently sent to the system control panel.
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
then, the siren is 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 silencing the
siren. When the detector chirps, you have to release the pressure
within 1 s. The switchover to postponed siren mode is confirmed
with 5 chirps. The detector LED flashes all the time during the
postponement.
Alarm memory: If it is enabled, LED indication continues even
when the smoke clears or when the temperature decreases. The
slow-flashing indication lasts 24 hours unless it is terminated by
pressing the detector body.
Tamper alarm: When the detector cover is opened, the detector
sends a tamper signal to the control panel.
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. The LED is 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. If the battery is low, 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 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 in SERVICE mode, a fire alarm is
triggered.
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 detector test can be carried out when a fault is signalled. To test the
detector, press its whole body against the base. During the test the
detector checks whether there is still a fault. The red LED flashes during
the test. When the test is completed, the LED stops flashing and the
detector then signals the result. A persistent fault is signalled by 3 flashes
and 3 beeps. If the fault has been fixed, the detector chirps briefly.
If you have not managed to fix the fault, the detector must be sent to
a service centre.
Battery replacement
The detector checks the battery status 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.
Exchange procedure:
- If the detector is already enrolled to the system it’s
necessary to enter service mode
- open the detector
- remove the old batteries
- press and hold the test button (8) until the LED (3) goes ON
- when the LED goes OFF , it shows the capacitors inside the
detector have been discharged
- insert some new batteries
Always replace all three batteries with the same type and
manufacturer.
Use only high-quality 1.5 V AA alkaline batteries.
Do not throw used batteries into ordinary household waste.
Deposit 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
corresponding address in the control panel memory.
