JABLOTRON SD-503ST Smoke And Heat Detector
Introduction
The JA-150ST is a component of the JABLOTRON system. We recommend you buy them together with the detector. The JJABLOTRON JA-150ST Smoke And Heat Detector 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.
Detector location
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.
Do not install the detector in an environment exposed to dust, cigarette smoke, and steam. Dusty environments shorten the detector’s lifespan.
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.
Installtion
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 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 g 4. There is 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), then the detector can be installed as in g 5.
- centre of the room, best location
- acceptable location
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 reduce detector sensitivity, thus causing false alarms and detection faults).
- Within a 1m radius of fluorescent tubes or energy-saving light bulbs (electrical interference may negatively affect the detector’s radio communication)
- In areas with lots of small insects
Installation
Abide by the procedures recommended in the previous paragraphs.
Detector cover opening; 2 – detector cover closing; 3 – optical status signalling; 4 – arrow showing where to insert the detector onto the bottom part; 5 – production code; 6 – configuration jumpers; 7 – battery holders; 8 – arresting screw
Instructions
- Open the detector cover by turning it anti-clockwise (1).
- Attach the removed plastic base to the JABLOTRON JA-150ST Smoke And Heat Detector desired place with screws.
- Set the configuration jumpers (6) according to the table below.
- Proceed according to the control panel installation manual. Basic procedure:
- Go to the F-Link program, select the required position in the Devices window, and launch Enrollment mode by clicking on the Enroll option.
- Insert all batteries into the detector.
- Insert the detector into the plastic base. Close the detector cover by turning it clockwise (2).
- During this period of time, the detector doesn’t detect anything. The test ends when the LED shuts down (3), and the detector becomes fully operational.
- To be fully compliant with regulations, it is necessary to lock the cover in place with the use of an (8) arresting screw.
Detector settings
Jumper 1 MEM – Signalling the alarm memory. The JABLOTRON SD-503ST Smoke And Heat Detector signalling LED remains active for 24 hours after the reason for the alarm ceases to exist. Jumper 2 and 3 TEMP and SMOKE – The combination of these configuration jumpers defines how the detector will react to smoke and heat. It’s possible to change the system’s reaction to something other than Fire using the F-Link program. This setting is in the Reaction options in the Devices window.
Fire alarm
- Optical detector: The indication lasts until the room is ventilated (thus also ventilating the detector’s detection chamber).
- Heat detector: The indication lasts until the temperature drops (e.g., when the room is ventilated).
- Alarm memory: If enabled, the LED alarm indication continues flashing slowly (approx. 4 times per second) for a further 24 hours after the alarm stops.
Battery replacement
The system sends a report automatically when the battery is low. Optical indication then flashes briefly once every 30 seconds. It is always essential to replace all three batteries. Use the same type and the same brand for all of them. Wait for 90 seconds to let the detector’s circuitry discharge before inserting new batteries.
Fault indication
The detector checks its functionality. An operating temperature range fault will disappear the moment the temperature of the environment returns to normal. If JABLOTRON SD-503ST Smoke And Heat Detector this test results in a fault, send the detector to the repair service.

FAQs
What hazards does the SD-503ST detect?
The SD-503ST offers accurate early fire detection by detecting both smoke and sharp temperature spikes.
Is this detector wireless or wired?
Since the SD-503ST is a wireless detector, wiring is not necessary for flexible installation.
Where is the best place to install the SD-503ST?
To prevent false alarms, place the detector high on the wall or on the ceiling, away from kitchens, heating vents, and draughty places.
Can I install the detector myself?
Yes, DIY installation is made simple by the wireless design. For best results, please follow the installation instructions.
How does the SD-503ST alert me to smoke or heat?
It wirelessly alerts your Jablotron control panel when it detects smoke or a sharp increase in temperature, which sets off alarms or messages.
Does the detector have a test mode?
Indeed, a test button on the detector allows you to use the control panel to verify its performance and signal strength.
How often should I test the detector?
To make sure your detector is functioning correctly and keeping a strong connection with the control panel, test it once a month.
How do I clean the detector?
Use a gentle, dry towel to clean the detector. Steer clear of cleaning solvents and water.
