Simultaneously, the detector will beep + the red LED will flash repeatedly 3 times followed by 1.5
seconds of silence.
The duration of one beep + flash is 0.5 seconds.
The detector will beep + the red LED will flash constantly and rapidly if increased temperature (fire)
is detected.
The duration of one beep + flash in this case is 0.2 seconds.
If several detectors are wirelessly interconnected and one of the detectors enters an alarm state,
other paired detectors will also begin emitting an acoustic + optical signal in the form of 2 rapid beeps
followed by 1.2 seconds of silence.
If an alarm triggers, immediately evacuate the building and make sure all other people have left as well.
Do not stop to call help or pick up your things.
Contact the corresponding emergency service.
Manual silencing of alarm during alarm trigger
The acoustic signal of the alarm can be temporarily silenced.
Press the main button; the acoustic signal will be silenced for 10 minutes.
The silencing will be indicated by 1 flash of red LED every 8 seconds.
Only use the silence function in cases of false alarms caused, for instance, by steam, vapour from
cooking or burned food. Wait until the air clears.
If you have multiple paired detectors in alarm state, you will have to silence each detector separately.
Do not remove the batteries to stop the alarm state – this will deactivate the alarm!
Wireless connection between detectors
Smoke detectors GS558 can be wirelessly interconnected with one another. This interconnection
allows the loud acoustic alarm (85 dB) to spread among the devices if one of the detectors detects
smoke. This feature is especially useful for larger, multi-storey buildings.
Warning: Since the detector is fitted with wireless connection, do not mount the detector(s) onto a
metal base. Doing so may decrease wireless range.
To pair additional detectors, do the following:
Pairing detectors
1. Long-press the main button for 12 seconds on the first detector. The red LED will light up – the
detector is ready for pairing (this mode lasts for 30 seconds, then the detector switches to
standard mode!).
Note: If you wish to cancel pairing mode prematurely, short-press the main button; the red LED
will switch off.
2. Press and hold the main button for 1–2 seconds on the second detector. The red LED will flash
rapidly several times on both the first and second detector simultaneously – both detectors
are interconnected.
If you wish to pair additional detectors, proceed again from step 2. Using this process, you can pair
a maximum of 30 detectors. Remember that maximum wireless range is 20 m. In busy areas, the
range can decrease to up to 1/3rd.
Erasing memory of paired detectors
1. Long-press the main button for 16 seconds on the detector.
2. Wait until the red LED begins flashing rapidly – let go of the main button.
3. Then, press the main button quickly 2× – a beep will sound upon the second press and the red
LED will stop flashing – the memory of the detector is erased.
You can repeat the process for other detectors to erase their memory.
Testing paired detectors
Press and hold the main button of the detector for max. ca 45 seconds.
Gradually, all other paired detectors will start beeping.
This allows you to check that the detectors have been paired correctly.
You can cancel the alarm mode for beeping detectors by pressing the main button.
The detectors will switch to manual alarm silence for 10 minutes.
Then, they automatically switch to standard mode.
