The HD100 RF wireless methane gas detector is a state-of-the-art device designed and built in Romania. The HD100 RF will communicate with an HD200 RF centralizer (finder). This wireless methane gas detector will send an alert to the central controller, triggering the solenoid valve on the building’s gas main (or stairwell).

The wireless gas detector has been designed to eliminate the discomfort of drilling through walls, a necessary action for the cable route to the solenoid valve. Allows immediate installation and activation via the mounting plate and plugging the plug into the socket. The radio-frequency detector allows a large number of apartments to be connected very quickly and efficiently. The alarm signal is transmitted via radio waves over a distance of 50 to 300 m. Thanks to the carefully calibrated sensor, the risk of false alarms is reduced.



HD100 RF Strong alarm
Strong alarm You’ll hear it immediately when it triggers the alarm/electrovalve thanks to the 85 decibel piezo siren!
HD100 RF Even 300 m coverage
Even 300 m coverage The alarm signal is transmitted via radio waves over a distance of 50 to 300 m or optionally via a wire through the pre-installed control port.
HD100 RF Gas detection activated!
Gas detection activated! It only takes 60 seconds from power up to methane gas detection activation!

Frequent questions

Why is the yellow LED always on?
This indicator warns that the gas sensor is not working properly. Contact a Homplex representative to identify the cause and/or replace the methane gas detector. As long as the yellow LED is lit, the detector does not measure and does not respond if the dangerous level of methane gas in the room is exceeded!
How can I tell if the detector is working properly?
After powering up, wait 15 seconds for the self-test process to complete. When this process is complete the red and orange LEDs will go out and the green LED will light solid. Press the Test button for 5 seconds to verify. The detector will acoustically and visually signal a possible danger and send a signal to close the solenoid valve.
Simt miros de gaz, dar detectorul nu reacționează
The unpleasant and easily recognisable smell (an unpleasant sulphurous odour) of natural gas used in homes is due to odorant additives, such as tert-butylthiol, which are used for safety. Most people can detect this smell at fairly low levels of gas concentration (2% L.I.E. or less), but certain disabilities or advancing age can lead to a reduction in this smell sensitivity. The L.I.E. (Lower Explosive Limit) of the gas defines the minimum volume ratio of combustible gas or vapour in the air in which an explosive atmosphere will form. The detector is calibrated to trigger the alarm at the threshold of 10% of the L.I.E. of the detected gas. Thus, it is possible for a person to smell gas before the alarm is activated. This does not necessarily indicate a fault in the device. For humans, a gradual increase in gas concentration may also go unnoticed due to olfactory fatigue. Translated with (free version)
